It should be understood that the implementation of all of the illustrated components is not a necessity, and that more or fewer components can be implemented. alternatively.
    [0011] Referring now to FIG. 1A, the mobile terminal 100 is shown having a wireless communication unit 110 configured with a plurality of components currently in use. For example, the wireless communication unit 110 typically includes one or more components that allow wireless communication between the mobile terminal 100 and a wireless communication system or network within which the mobile terminal is located. The wireless communication unit 110 typically includes one or more modules that enable communications such as wireless communications between the mobile terminal 100 and a wireless communication system, communications between the mobile terminal 100 and another mobile terminal, communications between the mobile terminal 100 and an external server. In addition, the wireless communication unit 110 typically includes one or more modules that connect the mobile terminal 100 to one or more networks. To facilitate such communications, the wireless communication unit 110 includes one or more of a broadcast receiving module 111, a mobile communication module 112, a wireless Internet module 113, a short-range communication module 114, and a location information module 115. The input unit 120 includes an image capture apparatus 121 for obtaining images or a video, a microphone 122, which is a type of audio input device for inputting a video. audio signal, and a user input unit 123 (for example, a touch key, a push button, a mechanical key, a programmable key, and the like) to allow a user to enter information. Data (eg, audio, video, image, and the like) is obtained by the input unit 120 and can be analyzed and processed by the controller 180 according to device parameters, user instructions, and associations of these. The detection unit 140 is typically implemented using one or more sensors configured to detect internal information of the mobile terminal, the near-mobile environment, user information, and the like. For example, in FIG. 1A, the detection unit 140 is shown having a proximity sensor 141 and a lighting sensor 142. If desired, the detection unit 140 may alternatively or additionally include d other types of sensors or devices, such as a touch sensor, an acceleration sensor, a magnetic sensor, a gravity sensor, a gyro sensor, a motion sensor, a RGB sensor, an infrared (IR) sensor , a digital scanning sensor, an ultrasonic sensor, an optical sensor (for example, the camera 121), a microphone 122, a battery meter, an environmental sensor (for example, a barometer, a hygrometer, thermometer, radiation detection sensor, thermal sensor, and gas sensor, among others), and a chemical sensor (e.g., electronic nose, health sensor, biometric sensor, and the like) , to name a few. The mobile terminal 100 can be configured to use information obtained from the detection unit 140, and in particular, information obtained from one or more sensors of the detection unit 140, and associations of them. Output unit 150 is typically configured to output various types of information, such as audio, video, touch output, and the like. The output unit 150 is shown having a display unit 151, an audio output module 152, a haptic module 153, and an optical output module 154. The display unit 151 may have an inter-layer structure or an integrated structure with a touch sensor to facilitate a touch screen. The touch screen may provide an output interface between the mobile terminal 100 and a user, as well as serve as a user input unit 123 which provides an input interface between the mobile terminal 100 and the user. The interface unit 160 serves as an interface with various types of external devices that can be coupled to the mobile terminal 100. The interface unit 160, for example, can include any of wired or wireless ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, input / output ports (1/0 ) audio, video 1/0 ports, headset ports, and the like. In some cases, the mobile terminal 100 can perform matching control functions associated with a connected external device, in response to the device that is connected to the interface unit 160. The memory 170 is typically implemented to store data. to support various functions or features of the mobile terminal 100. For example, the memory 170 may be configured to store application programs executed in the mobile terminal 100, data or instructions for operations of the mobile terminal 100, and the like. Some of these application programs can be downloaded from an external server via wireless communication. Other application programs may be installed in the mobile terminal 100 during manufacturing or shipping, which is typically the case for basic functions of the mobile terminal 100 (for example, receiving a call). , making a call, receiving a message, sending a message, and the like). It is common for application programs to be stored in the memory 170, installed in the mobile terminal 100, and executed by the controller 180 to perform an operation (or function) for the mobile terminal 100. Control apparatus 180 typically serves to control the overall operation of the mobile terminal 100, in addition to the operations associated with the application programs. The controller 180 can provide or process information or functions appropriate for a user by processing signals, data, information and the like, which are inputted or outputted by the various components illustrated in FIG. 1A, or by activating Application programs stored in the memory 170. For example, the control apparatus 180 controls some or all of the components shown in FIGS. 1A-1C according to the execution of application programs that have been stored. in the memory 170. The electric power supply unit 190 may be configured to receive external electrical power or to provide internal electrical power to provide appropriate electrical power required to operate electrical power sources. elements and components included in the mobile terminal 100. The electrical power supply unit 190 may include a battery, and the battery may be e configured to be incorporated in the terminal body, or configured to be removable from the terminal body. Still referring to Figure 1A, various components illustrated in this figure will now be described in more detail. With respect to the wireless communication unit 110, the broadcast receiving module 111 is typically configured to receive a broadcast signal and / or broadcast related information from an external broadcast management entity 25. via a broadcast channel. The broadcast channel may include a satellite channel, a terrestrial channel, or both. In some embodiments, two or more broadcast receiving modules 111 may be used to facilitate the simultaneous reception of two or more broadcast channels, or to support switching among broadcast channels. Referring now to FIGS. 1B and 1C, the mobile terminal 100 is described with reference to a bar-type terminal body. However, the mobile terminal 100 may be implemented alternatively in any of a variety of different configurations. Examples of such configurations include a watch type, bar type, eyeglass type, or foldable type, flap type, sliding type, toggle type, and swivel type in which two and more bodies are associated with each other in a relatively mobile manner, and associations thereof. The description herein will often refer to a particular type of mobile terminal (eg, a bar type, a watch type, a goggle type, and the like). However, such teachings with respect to a particular type of mobile terminal will generally apply to other types of mobile terminals as well. The mobile terminal 100 will generally include a housing (eg, frame, housing, cover, and the like) forming the appearance of the terminal. In this embodiment, the housing is formed using a front housing 101 and a rear housing 102. Various electronic components are incorporated in a gap formed between the front housing 101 and the rear housing 102. At least one middle housing can further positioned between the front housing 101 and the rear housing 102.
    [0012] The display unit 151 is shown located on the front side of the terminal body to output information. As illustrated, a window 151a of the display unit 151 may be mounted on the front housing 101 to form the front surface of the terminal body together with the front housing 101. In some embodiments, electronic components may also be mounted on the back box 102. Examples of such electronic components include a removable battery 191, an identification module, a memory card, and the like. A rear cover 103 is shown covering the electronic components, and this cover can be detachably coupled to the rear housing 102. Thus, when the rear cover 103 is removed from the rear housing 102, the electronic components mounted on the rear housing 102 are exposed. externally. As illustrated, when the rear cover 103 is coupled to the rear housing 102, a side surface of the rear housing 102 is partially exposed. In some cases, when mating, the rear housing 102 may also be completely protected by the rear cover 103. In some embodiments, the rear cover 103 may include an opening for externally exposing a camera 121b or an audio output module 152b.
    [0013] The housings 101, 102, 103 may be formed by injection molding a synthetic resin or may be formed of a metal, for example, stainless steel (STS), aluminum (Al), titanium (Ti), or the like. Instead of the example in which the plurality of housings form an interior space for housing components, the mobile terminal 100 may be configured such that a housing forms the interior space. In the present example, a mobile terminal 100 having a uni-body is formed such that a synthetic resin or metal extends from a side surface to a back surface. If desired, the mobile terminal 100 may include a water seal unit (not shown) to prevent the introduction of water into the terminal body. For example, the water seal unit may include a water seal element that is located between the window 151a and the front housing 101, between the front housing 101 and the rear housing 102, or between the rear housing 102 and the rear cover 103, for sealing an interior space when these housings are coupled.
    [0014] FIGS. 1B and 1C illustrate certain components as they are arranged on the mobile terminal. However, it is to be understood that other arrangements are possible and within the teachings of the present disclosure. Some components may be omitted or rearranged. For example, the first handling unit 123a may be located on another surface of the terminal body, and the second audio output module 152b may be located on the side surface of the terminal body. The display unit 151 outputs information processed in the mobile terminal 100. The display unit 151 may be implemented using one or more appropriate display devices. Examples of such suitable display devices include a liquid crystal display (LCD) screen, a thin film transistor (TFT-LCD) liquid crystal display, an organic light-emitting diode (OLED), a flexible screen, a three-dimensional (3D) screen, an electronic ink screen, and associations thereof. The display unit 151 may be implemented using two display devices, which may use the same or a different display technology. For example, a plurality of display units 151 may be arranged on one side, spaced from each other, or these devices may be integrated, or these devices may be arranged on different surfaces.
    [0015] The display unit 151 may also include a touch sensor that detects a touch input received on the display unit. When a touch is input to the display unit 151, the touch sensor can be configured to detect that touch and the controller 180, for example, can generate a control command or other signal corresponding to the touch. Content that is entered in a tactile manner can be a text or numeric value, or a menu item that can be embedded or designated in various modes. The touch sensor may be configured as a film having a touch profile, disposed between the window 151a and a display screen on a rear surface of the window 151a, or a wire which is patterned directly on the back surface of the window. the window 151a. Alternatively, the touch sensor may be formed integrally with the display screen. For example, the touch sensor may be disposed on a substrate of the display screen or within the display screen.
    [0016] The display unit 151 may also form a touch screen together with the touch sensor. Here, the touch screen can serve as a user input unit 123 (see Figure 1A). Thus, the touch screen can replace at least some of the functions of the first handling unit 123a. The first audio output module 152a may be implemented as a speaker for outputting voice audio, alarm sounds, multimedia audio reproduction, and the like. The window 151a of the display unit 151 will typically include an aperture to allow audio generated by the first audio output module 152a to pass. An alternative is to allow audio to be released along an assembly gap between the structural bodies (for example, a gap between the window 151a and the front housing 101). In this case, an independently formed hole for outputting audio sounds may not be seen or otherwise disguised in appearance, further simplifying the appearance and fabrication of the mobile terminal 100. The optical output module 154 may be configured to exit light 30 to indicate event generation. Examples of such events include message reception, call waiting reception, missed call, alarm, calendar announcement, email reception, receipt of information via an application, and the like. When a user has controlled a generated event, the controller may control the optical output unit 154 to stop the light output. The first camera 121a can process image frames such as inanimate or animated images obtained by the image sensor in a capture mode or a video call mode. The processed image frames can then be displayed on the display unit 151 or stored in the memory 170. The first and second handling units 123a and 123b are examples of the user input unit 123, which can be manipulated by user to provide input to the mobile terminal 100. The first and second handling units 123a and 123b may also be commonly referred to as manipulative parts, and may utilize any tactile method that allows the user to perform a manipulation such as touching, pushing, scrolling, or the like. The first and second handling units 123a and 123b may also utilize any non-tactile method that allows the user to perform manipulation such as proximity touch, stationary float, or the like. Figure 1B illustrates the first handling unit 123a as a touch key, but other possibilities include a mechanical key, a push button, a touch key, and combinations thereof. An input received in the first and second handling units 123a and 123b can be used in a variety of ways. For example, the first handling unit 123a can be used by the user to provide menu entry, a home key, a cancel, a search, or the like, and the second handling unit 123b can be used by the user for providing an input for controlling a volume level produced from the first or second audio output module 152a or 152b, to switch to a touch recognition mode of the display unit 151, or the like. As another example of the user input unit 123, a rear input unit (not shown) may be located on the rear surface of the terminal body. The rear input unit may be manipulated by a user to provide input to the mobile terminal 100. The input may be used in a variety of different ways. For example, the rear input unit may be used by the user to provide an input for turning on, off, starting, terminating, scrolling, controlling the volume level produced from the first or second audio output module 152a or 152b, switch to a touch recognition mode of the display unit 151, and the like. The rear input unit may be configured to allow touch input, push input, or combinations thereof.
    [0017] The rear input unit may be located to overlap the display unit 151 on the front side in a thickness direction of the terminal body. For example, the rear input unit may be located on a rear end portion of the rear side of the terminal body so that a user can easily manipulate it using the index when the user grasps the terminal body with a hand. Alternatively, the rear input unit may be positioned at virtually any location on the rear side of the terminal body. Embodiments that include the rear input unit may implement some or all of the functionality of the first handling unit 123a in the rear input unit. As such, in situations where the first handling unit 123a is omitted from the front side, the display unit 151 may have a larger screen. As an additional possibility, the mobile terminal 100 may include a digital scanning sensor that scans a user's fingerprint. The controller 180 can then use fingerprint information detected by the digital scan sensor as part of an authentication procedure. The digital scanning sensor may also be installed in the display unit 151 or implemented in the user input unit 123. The microphone 122 is shown located at one end of the mobile terminal 100, but other locations are possible. If desired, multiple microphones can be implemented with such an arrangement for receiving stereo sounds. The interface unit 160 may serve as a path for the mobile terminal 100 to interface with external devices. For example, the interface unit 160 may include one or more of a connection terminal 30 for connection to another device (e.g., a headset, an external speaker, or the like), a communication port a near field (e.g., an IrDA port, a Bluetooth port, a wireless LAN port, and the like), or an electrical power supply terminal for supplying power to the mobile terminal 100. The interface 160 may be implemented in the form of a connector for housing an external card, such as a subscriber identification module (SIM), a user identification module (UIIVI), or a memory card for information storage.
    [0018] The second camera 121b is shown located on the rear side of the terminal body and includes an image capture direction which is substantially opposite to the image capture direction of the first camera capture unit. 121a views. If desired, the second camera 121a may alternatively be located at other locations, or made to be movable, to have an image capture direction different from that shown. The second camera 121b may include a plurality of lenses arranged along at least one line. The plurality of lenses may also be arranged in a matrix configuration. Cameras may be referred to as "networked cameras". When the second camera 121b is implemented as a networked camera, images can be captured in a variety of ways using the plurality of lenses and images with better qualities. As shown in FIG. 1C, a flash 124 is shown adjacent to the second 12 lb camera. When an image of a subject is captured with the camera 121b, the flash 124 may illuminate the subject. As shown in FIG. 1B, the second audio output module 152b may be located on the terminal body. The second audio output module 152b may implement stereophonic sound functions together with the first audio output module 152a, and may also be used to implement a speakerphone mode for call communication. At least one antenna for wireless communication may be located on the terminal body. The antenna may be installed in the terminal body or formed by the housing. For example, an antenna that configures a portion of the broadcast receiving module 111 may be retractable into the terminal body. Alternatively, an antenna may be formed using a film attached to an inner surface of the back cover 103, or a housing that includes a conductive material.
    [0019] An electrical power supply unit 190 for providing power to the mobile terminal 100 may include a battery 191, which is mounted in the terminal body or releasably coupled to an outside of the terminal body. The battery 191 can receive electrical energy via an electrical power source cable connected to the interface unit 160. Also, the battery 191 can be wirelessly recharged using a wireless charger. . The wireless charge can be implemented by magnetic induction or electromagnetic resonance. The rear cover 103 is shown coupled to the rear housing 102 to protect the battery 191, to prevent separation of the battery 191, and to protect the battery 191 from external impact or foreign matter. When the battery 191 is removable from the terminal body, the rear housing 103 can be detachably coupled to the rear housing 102. An accessory to protect line appearance or assist or increase the functions of the mobile terminal 100 can also be provided on the mobile terminal. As an example of an accessory, a cover or cover for covering or housing at least one surface of the mobile terminal 100 may be provided. The cover or the pocket can cooperate with the display unit 151 to increase the function of the mobile terminal 100. Another example of the accessory is a touch pen to assist or increase a touch input on a touch screen. More preferred embodiments will be described in more detail with reference to additional drawing figures. Those skilled in the art will understand that the present features can be realized in several forms without departing from their characteristics.
    [0020] Fig. 2 is a flowchart illustrating a method for controlling the mobile terminal according to an embodiment of the present invention. The mobile terminal 100 can detect a touch input via the touch screen 151 (S100). The touch input may include a touch input by a user's finger, a touch input by a touch pen and the like. The touch screen 151 may recognize a touch of a user's body part other than a user's finger as a predetermined touch input.
    [0021] According to one embodiment of the present invention, a touch input by a finger of a user can be distinguished from various touch input inputs via the touch screen 151. It is necessary to ignore an unintended touch input. and normally process only a desired touch input, since the touch sensitivity of the touch screen 151 increases. Meanwhile, when a fingerprint sensor is integrated with the display unit 151, the processing efficiency decreases if all the touch sensors uniformly arranged in the touch screen for the fingerprint recognition are used to obtain a fingerprint image.
    [0022] According to one embodiment of the present invention, it is determined whether a touch input applied through the touch screen 151 is a touch input by a human finger and then a fingerprint image is acquired only when a function corresponding to the touch input requires fingerprint authentication.
    [0023] The controller 180 can determine whether the touch input is a touch input by a user's finger (S110). When the controller 180 determines that the touch input is not an input using a user's finger, the controller 180 can switch to touch input processing based on the touch input. received. For example, when touch input is performed using a stylus and authentication is required, a window may be displayed to enter a signature, password, passcode, or the like. If the touch input does not require authentication, the received touch input can be processed as a normal touch input. When it is determined that the touch input is an input using a user's finger, in step 5110, the controller 180 can determine whether user authentication is required for touch input. received. If authentication is not required, the touch input can be processed as a normal input using the user's finger (S121). Otherwise, if authentication is required, a user interface to authenticate the user can be provided (S130). The user interface for authentication when the input is a digital input may be different from a displayed interface for touch inputs using other means, for example, to authenticate using fingerprint authentication rather than a password or other means. A description will be provided of a method for determining whether a touch input applied to the touch screen 151 is a touch input by a user's finger according to a predetermined touch algorithm. FIG. 3 illustrates a tactile detection system of the mobile terminal according to an embodiment of the present invention and FIG. 4 is an equivalent circuit diagram of the touch screen shown in FIG. 3. Referring to FIGS. the touch screen sensing system 151 may be implemented as a capacitive touch sensing system which detects touch input through a plurality of capacitance sensors. The touch sensor system may include the touch screen (TSP) 151, a touch screen exciter circuit, and the like. The touch screen TSP includes Tx channels Tx 1 to TxN (N being a positive integer), channels Rx Rx 1 to RxM (M is a positive integer) intersecting Tx channels Tx1 to TxN and MxN touch sensors Cm formed at intersections of Tx channels Tx1 to TxN and Rx channels Rx 1 to RxM. Each touch sensor Cm has a mutual capacitance. The touch screen exciter circuit may include a touch sensing circuit 10 and a coordinate calculator 16. The touch screen exciter circuit may provide an excitation signal to the touch screen TSP in order to detect voltage variations in touch sensors and transmit coordinate information to a touch input point to a module that requires the coordinate information.
    [0024] The touch sensor circuit 10 may include a Tx excitation circuit 12, an Rx excitation circuit 14 and a Tx / Rx control apparatus 18, etc. The touch sensor circuit 10 applies an excitation signal to the touch sensors via the Tx channels Tx1 to TxN using the excitation circuit Tx 12 in a normal operating mode and detects voltages of the touch sensors Cm by via the channels Rx Rx 1 to RxM and the excitation circuit Rx 14 in synchronization with the excitation signal in order to output digital tactile raw data.
    [0025] The touch detection circuit 10 and the coordinate calculator 16 can be integrated into a touch-sensitive IC. The excitation circuit Tx 12 selects a channel Tx which outputs an excitation signal in response to a control signal Tx from the control unit Tx / Rx 18 in the normal operating mode and applies the signal of excitation on Tx channels Tx 1 to TxN connected to the selected Tx channel. The Tx channels Tx 1 to TxN are charged during a high voltage period of the excitation signal to provide charges to the touch sensors Cm and discharged during a low voltage period of the excitation signal.
    [0026] The Rx excitation circuit 14 accumulates a touch sensor voltage in a capacitor Cs of a predetermined integrator in synchronization with the excitation signal and converts the accumulated voltage into digital data via an analog-digital converter ( called "ADC" below) to output tactile raw data. A change in voltage in a touch sensor before the touch is applied and after the touch is applied is described. When a touch sensor is touched, a capacitance C of the touch sensor is reduced according to Q (load) = C (capacitance) XV (voltage) and thus a voltage variation in the touch sensor before the touch is applied and after the touch is applied on it is larger than those in other touch sensors on which a touch input is not applied. Therefore, it is possible to determine whether a touch input is present according to a touch sensor voltage variation before and after touch. The Rx excitation circuit 14 converts a tactile sensor voltage variation before and after touch into tactile raw data which is digital data and provides the tactile raw data to the coordinate calculator 16. The coordinate calculator 16 executes an algorithm of predetermined tactile recognition to compare the raw touch data received from the Rx excitation circuit 14 to a predetermined threshold in the normal operating mode. Any known algorithm can be used as a tactile recognition algorithm. The tactile recognition algorithm detects tactile raw data that exceeds the threshold. Tactile raw data that exceeds the threshold is determined to be tactile data obtained from touch sensors on which a touch input is applied. The coordinate calculator 16 executes the tactile recognition algorithm to calculate touch data coordinates that exceed the threshold. In addition, the coordinate calculator 16 may transmit coordinate information about touch data that exceeds the threshold to a host system that requires the coordinate information. The coordinate calculator 16 may be implemented as a microcontroller unit (MCU). Figs. 5A and 5B illustrate a procedure for determining whether or not a touch input is applied by a user's finger in the display unit of the mobile terminal according to an embodiment of the present invention.
    [0027] Referring to FIGS. 5A and 5B, the mobile terminal 100 according to one embodiment of the present invention can be implemented so that the mobile terminal detects a touch input only via TxA, TxB, TxC channels, TxD, RxA, RxB, RxC and RxD arranged in a specific one of a plurality of Tx channels and a plurality of Rx channels, which are arranged in crossing at predetermined intervals. For example, when the mobile terminal enters a sleep mode to reduce power consumption, only Tx channels in a specific interval are enabled and other Tx channels are in a pending state. When a capacitance change is detected due to a touch input, capacitance variations with respect to all channels (e.g., all Rx channels present between RxB and RxD channels) present between channels (e.g. RxC channel) from which a capacitance change is detected are detected and binarization for a unidimensional straight line is performed (refer to Figure 5B). When capacitances detected through the channels exceed the threshold, the capacitances are treated as "1". When capacitances detected through the channels are below the threshold, the capacitances are treated as "0". When the sensed capacitances alternate between 1 and 0, the controller 180 can determine that the corresponding touch input 30 is a touch input by a user's finger (refer to Fig. 5B). A user's fingerprint has ridges protruding from the outer skin and hollows between ridges and people have different ridges and troughs. Touch sensor channels can detect different capacitance variations with respect to peaks and troughs of the user's fingerprint. Therefore, when capacitance variations generated in the channels of the touch sensors according to the fingerprint of the user are digitized, 1 and 0 are generated alternately. The controller 180 of the mobile terminal 100 can receive this information from the touch-sensitive IC and determine whether the corresponding touch input is applied by a user's finger or a touch pen. When touch input by the touch pen is received, the touch IC can not detect a pattern of capacitance variation (pattern in which 1 and 0 are generated alternately) as described above, and thus the apparatus 180 determines that the corresponding touch input is not the touch input by the finger of the user (S110: NO). The touch input can then be processed as a non-digital touch input or a normal touch input (S111, S121). When determining that the touch input is not the touch input by the user's finger (S110: NO), the controller 180 may recognize the touch input as, for example, an input touch by the touch pen. In this case, the controller 180 can process the touch input by the touch pen. When the controller 180 determines that the touch input is not the touch input by the user's finger (5110: NO), the controller 180 can recognize the touch input as a contact of a body part (for example the back of a hand, a palm, a face or the like) of the user other than the fingers and ignore the touch input. Namely, the controller 180 does not need to perform operation to acquire a fingerprint image for fingerprint authentication when determining that the touch input is not the same. touch input by the user's finger, and thus the efficiency of the processor can be improved. A description will be provided of mobile terminal operations when determining that a touch input by the user's finger is received. Fig. 6 illustrates a procedure for acquiring fingerprint information in the mobile terminal according to an embodiment of the present invention. Referring to Fig. 6, the mobile terminal 100 according to one embodiment of the present invention may include a 15 lb touch-sensitive IC and an application processor (AP) 181a integrated with the touch-screen 151.
    [0028] The 15 lb touchchart can be implemented such that a touchscreen excitation circuit (TSP) and a coordinate calculator for calculating coordinates of a touch point are integrated in a chip, as is described with reference to FIG. 3. The application processor 181a may be provided as a separate module or the controller 180 may perform all the functions of the application processor 181a. The touch-sensitive IC 151b processes a received touch input and transmits a touch report to the application processor 181a (S201). The touch report may include information (human finger) indicating that the received touch input is a touch input by the user's finger and coordinate information about the touch point to which the touch input is applied. The application processor 181a can control whether additional authentication is required to perform a function corresponding to the touch coordinates (S203).
    [0029] That is, when the touch point to which the touch input is applied corresponds to a predetermined application, the application processor 181a can control whether the application is an application executed through additional authentication. When the application is an executable application without additional authentication (S203: NO), the application processor 181a may finish processing the touch input while executing the application in response to the touch input (S213). When the additional authentication is required (S203: YES), the application processor 181a may request the 15 lb touchchart to provide the user's fingerprint information (S205). The fingerprint information can be a fingerprint image. The touch-sensitive IC 151a can acquire a fingerprint image of a region with which the user's finger makes contact on the touch screen 151 (S207). The touch-sensitive IC 151a can obtain a fingerprint image of the user 30 through a scanning operation of a single region of the touch screen 151, which contacts the user's finger only at the request of the application processor 181a, as described above, rather than acquiring the fingerprint image each time a touch input by the user's finger is received . Therefore, processor resources, such as touch-sensitive IC, application processor, and the like, can be effectively utilized.
    [0030] The touch-sensitive IC 151b transmits the acquired fingerprint image to the application processor 181a (S209, fingerprint image report). The application processor 181a can perform fingerprint authentication by comparing the fingerprint image received from the touchpad 15b1 to pre-stored fingerprint information of the user (S211). The procedure for processing the touch input between the display unit 151 and the control apparatus 180 to more effectively perform fingerprint authentication via the fingerprint sensor has been described. A description will be given of examples of providing a user interface required for authentication differently depending on whether the touch input applied is the touch input by the user's finger according to one embodiment of the invention. the present invention. Fig. 7 illustrates an example of the registration of authentication information according to an embodiment of the present invention. A method for controlling the mobile terminal according to an embodiment of the present invention can be implemented in the mobile terminal 100 described above with reference to Figs. 1A to 5B. Referring to FIG. 7, the user can register his fingerprint information in the mobile terminal 100. The fingerprint record can be made by storing a fingerprint image (FIG. 7 (a)). ). A signature (Figure 7 (b)) or a password (Figure 7 (c)) can be associated with the stored fingerprint image and prerecorded. The user's fingerprint is recorded for a specific item so that fingerprint authentication is required when the item is executed. Figs. 8A-8D illustrate another example of the registration of authentication information according to an embodiment of the present invention.
    [0031] Referring to Fig. 8A, the controller 180 may receive a predetermined touch input for an Al application from one or more applications displayed on the touch screen 151 to enter a mode in which the fingerprint lock is set for the Al application.
    [0032] The predetermined touch input may include a long touch input applied to the Al application. With reference to Fig. 8B, the controller 180 may display a guide G 1, which indicates that the fingerprint lock is currently set for the application Al, on the touch screen 151 when receiving the long touch input applied to the application Al. When the guide G1 is provided, the user can intuitively know that the image fingerprint is being scanned and stored. Referring to Fig. 8C, a window Ni for entering a password corresponding to a fingerprint lock function setting for the application A1 may be provided. Therefore, the user can access the Al application via fingerprint authentication or password entry. Referring to Fig. 8D, the controller 180 displays a predetermined indicator I together with the application for which the fingerprint lock is set so that the user can easily recognize the application for which the lock according to the fingerprint has been set. Figs. 9A to 12B illustrate examples of providing a user interface for authentication differently depending on whether the touch input applied is the finger touch input of a user according to an embodiment of the present invention. invention. FIGS. 9A and 9B illustrate an example of the application of the method for controlling the mobile terminal according to one embodiment of the present invention for each application.
    [0033] Figs. 9A and 9B are views for explaining a lock setting authentication procedure for a specific application according to touch input means.
    [0034] Referring to Fig. 9A, when an input for selecting an Al application for which a lock is set is received, the controller 180 controls whether the input is a touch input by the user's finger according to the the aforementioned method and requests the tactile IC to provide the user's fingerprint information when determining that the application corresponding to the touch point must be authenticated. The controller 180 may provide a guide G2 indicating that fingerprint recognition is in progress on the touch screen 151 so that the user does not remove the finger from the touch screen 151.
    [0035] Referring to Fig. 9B, upon receiving an input to select the latched application A1, the controller 180 controls whether the input is a touch input by the user's finger via of the aforementioned process. When the controller 180 determines that the input is a touch input by a touch pen P and the application corresponding to the touch point must be authenticated, the control device 180 can display a window N2 to enter a predetermined graph. on the touch screen 151. Figures 10A and 10B illustrate an example of the application of the method for controlling the mobile terminal according to an embodiment of the present invention to a lock screen.
    [0036] Referring to Fig. 10A, the controller 180 may display an LS lock screen on the touch screen 151. When a touch input applied to the touch screen 151 is received while the lock screen LS is displayed, the controller 180 can control whether the touch input is a touch input by the user F's finger via the aforementioned method and determine whether authentication is required to perform a function corresponding to the to touch. Since the touch input is applied to the lock screen LS, the controller 180 may determine that authentication is required to cancel the lock mode. Therefore, the controller 180 can request the touch-sensitive IC to provide the user's fingerprint information and the touch-sensitive IC can acquire a fingerprint image. In this case, a guide G3 indicating that fingerprint image acquisition is in progress can be displayed on the touch screen 151 so that the user does not remove the finger. When the acquired fingerprint image is valid, the lock mode can be canceled and an HS home screen can be displayed on the touch screen 151. Referring to Fig. 10B, when a touch input applied on the touch screen 151 is received while the lock screen LS is displayed on the touch screen 151, the control device 180 can determine that the touch input is a touch input by the touch pen P during the control touching means via the aforementioned method. In this case, when a signature by the touch pen P is entered, a guide G4 indicating that an input signature recognition is in progress can be displayed on the touch screen 151. When the signature is valid, the mode lock can be canceled and the HS home screen can be displayed on the touch screen 151. While the examples of the touch input recognition by the finger of the user according to the touch algorithm when receiving of the touch input by the finger of the user, the control if authentication is necessary and the automatic scanning of the fingerprint image almost simultaneously with the reception of the touch input have been described, the present invention is not limited to this. For example, when a fingerprint input window is provided, the controller 180 may request the touch-sensitive IC to acquire a fingerprint image.
    [0037] Figs. 11A and 11B illustrate another example of fingerprint authentication via the method for controlling the mobile terminal according to an embodiment of the present invention. Referring to Fig. 11A, upon receiving a touch input to select the locked application A1, the controller 180 can control whether the touch input is a touch input by the user's finger. through the aforementioned method. The controller 180 may request the touch-sensitive IC to provide the user's fingerprint information and, at the same time, provide a fingerprint input window 30 on the touch screen 151 when determining that the application corresponding to the touch point must be authenticated. When the finger of a user further touches the fingerprint input window 30, the touch-sensitive IC can recognize the fingerprint of the user inputted through the fingerprint input window. digital 30.
    [0038] Therefore, a fingerprint recognition is not performed on the finger of the user coming into contact with the touch screen 151 before the fingerprint input window 30 is displayed, thus improving the performance of the fingerprint. use of resources.
    [0039] When it is determined that the fingerprint is valid as a result of the fingerprint authentication, an application execution screen may be displayed on the touch screen 151. When the valid fingerprint is associated to a predetermined password, the controller 180 may control the predetermined password to be automatically entered so that the application can be automatically executed without password entry during authentication. valid fingerprint. Referring to Fig. 11B, the controller 180 can determine that the touch input to select the locked application A1 is a touch input by the touch pen P. In this case, the control apparatus 180 can provide a screen B3 through which a predetermined password is entered in order to execute the application, on the touch screen 151. Although examples of providing a user interface for authentication differently depending on the fact the received touch input is a touch input by the user's finger and the fact that the authentication (eg fingerprint authentication, personal identification number entry, signature entry, and the like) is necessary to perform a predetermined function corresponding to a touch point have been described in the aforementioned embodiments, the present invention is not limited thereto. For example, when a fingerprint authentication is performed by a touch input by the user's finger, an item set as a secret item by the user can be opened. Figs. 12A and 12B illustrate an example of different setting of an article opening degree by the method for controlling the mobile terminal according to one embodiment of the present invention. Referring to Fig. 12A, upon receiving an input to select a locked application A2 (music player application), the controller 180 controls whether the input is a finger-touch input. a user Fi via the aforementioned method. In addition, the controller 180 may request the touch-sensitive IC to provide the fingerprint information of the user when determining that the application A2 corresponding to the touch-point must be authenticated. Referring to Fig. 12A, the controller 180 may provide the fingerprint input window 30 on the touch screen 151 and provide an option to acquire a fingerprint image when a F2 is received via the fingerprint input window 30. When determining that the acquired fingerprint image is valid, the controller 180 may display a first group of 41 music files and a second group of music files 42 on the touch screen 151. Here, the first group of music files 41 can be files that are opened independently of the fingerprint authentication while the second music file group 42 may be files that are opened when valid fingerprint authentication is performed. Referring to Fig. 12B, the controller 180 can determine that the touch input to select the locked application A2 is a touch input by the touch pen P. In this case, the control device 180 can display only the first group of music files 41 on the touch screen 151 20 and hide the second group of music files 42. Figures 13A-13D illustrate a mobile terminal operation for processing a touch input received when the touch input It is not the finger-touch input of a user according to the embodiment shown in Fig. 2 (eg, S111). Referring to Figs. 13A and 13B, the mobile terminal 100 according to one embodiment of the present invention can process only one touch input by the user's finger as a normal touch input when a touch input by the user's finger and tactile inputs according to the body parts of the user other than the finger are recognized. For example, a handwritten input 50 may be applied by the user's finger Fi to the touch screen 151, as shown in FIG. 13A. In this case, only the touch input by the user's finger Fi can be recognized as a normal touch input and a touch input by the other part of the user's hand (for example the palm 51a and at least one portion 51b touching the touch screen 151 when the user is tightening the fingers) can be ignored without being treated as a normal touch input. Referring to Fig. 13B, when the user enters the mobile terminal 100 with one hand, whereas a touch input by a finger F2 of the hand can be applied to select a predetermined item displayed on the touch screen 151, the hand of the user entering the mobile terminal 100 can touch an edge 61 of the touch screen 151. The control unit 180 can ignore the touch input applied to the edge 62.
    [0040] Referring to Fig. 13C, when a touch input by a user's body part other than a finger is recognized, the touch input may be ignored. For example, the controller 180 may ignore a touch input applied to a region 62 that contacts the user's face F3 when the mobile terminal 100 connects a call.
    [0041] As a result, termination of an unnecessary touch call is prevented while the call is connected. Referring to Fig. 13D, when the mobile terminal 100 receives a predetermined form of tape on the touch screen 151 with the finger of a user while the display unit 151 is turned off, the display unit 151 can be turned on and the lock mode can be canceled. In this case, the tape in the predetermined form can be recognized via the input 71 by the finger of a user F4 and a touch input by means other than the finger of a user can be ignored without being treated as a normal touch input. The mobile terminal and the method for controlling said terminal according to the present invention have the following advantages. According to at least one embodiment of the present invention, it is possible to process a touch input according to the purpose of touching the user by processing the touch input more precisely. Furthermore, according to at least one embodiment of the present invention, it is possible to acquire a fingerprint image of the user only when determining that a fingerprint authentication is required when a Touch input is received, effectively managing terminal resources.

As generally described and embodied herein, a mobile terminal may include a touch screen configured to detect touch inputs, and a control apparatus configured to determine whether a touch input is an input using a user's finger. . When it is determined that the touch input is a touch input using a user's finger and a function associated with the touch input requires authentication, a prescribed user interface for authentication is provided. The prescribed user interface for authentication when touch input is an input using a user's finger may be different from a user interface for authentication when the touch input is not an input using the finger of a user. The mobile terminal may include a fingerprint sensor integrated with the touch screen and configured to recognize a fingerprint. User fingerprint information can be acquired via the fingerprint sensor when the touch input is a touch input using the user's finger and authentication is required, and the intended function The touch input is executed when the acquired fingerprint information matches prerecorded fingerprint information. The touch screen may include a touch IC including a plurality of Tx lines, a plurality of Rx lines crossing the Tx lines, and touch sensors formed at intersections of the Tx lines and Rx lines. The touch IC can be configured to acquire a fingerprint image corresponding to touch sensors touched by the user's finger among the touch sensors. The controller may be configured to recognize coordinates of a touch point corresponding to the touch input and to acquire the fingerprint image via the touch-sensitive IC when fingerprint authentication is required to execute an application corresponding to the recognized coordinates. The controller may also be configured to provide on the touch screen an announcement indicating that acquisition of the user's fingerprint information via the fingerprint sensor is in progress.
    [0043] The controller may be configured to display a fingerprint input window on the touch screen and to acquire the fingerprint information of the user via the fingerprint sensor when user's finger touches the fingerprint input window.
    [0044] The fingerprint sensor can be activated when the fingerprint input window is displayed. The fingerprint sensor can be activated When it is determined that the touch input is a touch input using the finger of a user. In addition, the fingerprint sensor may be activated when it is determined that the touch input is a touch input using a user's finger and the function associated with the touch input requires authentication. The user interface for authentication when the touch input is not an input using the user's finger can be a window for entering a predetermined graph for authentication on the touch screen. The touch input can be an input using a stylus. The user interface for authentication when the touch input is not an input using the user's finger can also be a window to enter a password or passcode. Furthermore, when it is recognized that the touch input includes a touch by the user's finger and a user's body part other than the finger, the control device is configured to handle only the touch by the user's finger as a normal touch input. Functions requiring authentication may include at least one of a function to unlock a locked screen, a function to unlock a locked application, or a function to unlock a latched touch screen while turning on the touch screen from a locked state. stop.

The user interface for authentication when touch input is an input using the user's finger may be different from a user interface required for authentication when the touch input is not an input using the finger of a user.
    [0046] The method may further include acquiring fingerprint information from the user via a fingerprint sensor integrated with the touch screen when the touch input is an input using the finger of the user and authentication is required, and performing the function desired by the touch input when the acquired fingerprint information matches prerecorded fingerprint information. In addition, the fingerprint sensor may be activated when it is determined that the touch input is a touch input using the finger of a user and the function associated with the touch input requires authentication.
