    Field of the Invention
    [0001] The present invention relates to a graphical user interface (GUI) of a display device. More particularly, the present invention relates to a method and apparatus for providing a graphical user interface on an Active Matrix Organic LightEmitting Diode (AMOLED) LED screen of a device to reduce an effect pasted image. Background of the Invention
    [0002] When an still image is displayed on a liquid crystal display (LCD) for an undesirably prolonged period of time, the so-called pasted image effect may occur. In a case of a liquid crystal screen with a thin film transistor (Thin Film Transistor-LCD or TFT-LCD), the bonding of the liquid crystal to a static image causes a temporary ghost image, while it is caused, on the screen of active matrix organic light emitting diode (Active Matrix Organic Light-Emitting Diode - AMOLED), by reducing the emission efficiency of one of the pixels that emit lights to present a specific image as time progresses.
    [0003] More specifically, AMOLED is its own light-emitting device including red, green and blue pixels, and its brightness decreases as the accumulated display time is extended.
    [0004] Figure 1A is a graph that illustrates the decrease in brightness of the red, green and blue pixels as the accumulated display time is extended according to the related technique.
    [0005] Referring to Figure 1A, the brightness of all red, green and blue pixels decreases as time progresses, and the brightness of the blue pixel decreases relatively quickly, compared to the red and green pixels.
    [0006] More particularly, in the case of a highly gray image, all red, green and blue pixels are light emitters and, as the light emission time is prolonged, the brightness of all red, green and blue decreases in such a way that when the image is changed, the glued image effect occurs.
    [0007] Figure 1B illustrates an example of a pasted image effect according to the related technique.
    [0008] Referring to part [a] of figure 1B, in a state where a highly gray image is displayed in a first region 11, while a relatively little gray image is displayed in a second region 12, if the gray image is identical to that of first region 11 is displayed in the second region 12, a temporary ghost image appears in the first region 11, as shown in part [b] of figure 1B. This is because the brightness decreases more quickly in the first region 11 than in the second region 12.
    [0009] The pasted image bothers a user, even when a particular application is run.
    [0010] Therefore, there is a need for a method and a display device that are able to reduce the effect of pasted image caused by the display of a static image, for an undesirable extended period of time. Description of the Invention Technical problem

    [0037] Figure 2 is a block diagram illustrating a configuration of a display device in accordance with an exemplary embodiment of the present invention.
    [0038] With reference to figure 2, a display device 100 includes a storage unit 110, an input unit 120, a display unit 130, and a control unit 140.
    [0039] The storage unit 110 is a component for storing programs and data necessary for the functioning of the display device 100 and can store the operating system (OS) for the initialization of the device 100 and applications and data, as a display image , an audio, a video, and the like. The storage unit of 110 stores an algorithm to move items on the screen.
    [0040] Input unit 120 receives a key manipulation signal, introduced by the user, to control the display device and provides the signal to control unit 140. Input unit 120 can be implemented with a keyboard with keys, such as a 3x4 keyboard, a QWERTY keyboard, and a touch panel. Input unit 120 may include a predefined number of button keys, a selection key, a steering wheel key, and the like. The input unit generates a signal for running an application stored in the storage unit 110 to the control unit 140 according to a user input. Input unit 120 can generate a signal to shut down or on display unit 130 to control unit 140.
    [0041] The display unit 130 can be implemented with organic light emitting diodes (OLED), and preferably active matrix organic light emitting diode (AMOLED) screen. Display unit 130 generates a boot progress screen, a standby screen, a menu screen, and an application run screen. Display unit 130 is switched on / off under the control of an on / off control unit 141 and moves an item under the control of an item shift unit 142.
    [0042] The control unit 140 is a component for controlling the global operations of the display device 100 and includes the display on / off control unit 141 and the item displacement unit 142.
    [0043] The display on / off control unit 141 is responsible for the on / off control of display unit 130. The display on / off control unit 141 controls the on or off of display unit 130, in response to display shutdown or input signal via input unit 120. Display on / off control unit 141 starts a timer by turning on display unit 130 to count the elapsed time and turns off the display unit 130, when the elapsed time reaches a predefined value.
    [0044] The item displacement unit 142 is responsible for controlling the change of an item in position on the display unit 130.
    [0045] In accordance with an exemplary embodiment of the present invention, the item can be an image object providing information on the current state of the display device 100 and can be an application execution icon. In a case where the display device 100 is a mobile communication terminal, the image object providing information about the current state of the display device 100 can be an indicator of cellular radio reception intensity, a Wi radio reception intensity. -Fi, a current time, battery information, an alarm setting, a Bluetooth on / off state, or a GPS on / off state. According to an exemplary embodiment of the present invention, a plurality of image objects providing information on the current status of the display device 100 can be arranged on a line in each specific region of the display unit 130. For example, the image objects can be arranged in a horizontal direction in the upper region of the display unit 130.
    [0046] The item shift unit 142 can control the display unit 130 to display items in positions at a predefined distance from their previous positions, in response to an input command to turn the display on in the off state of the display unit 130.
    [0047] The item displacement unit 142 can also determine whether a timer started when items are arranged in their positions reaches a predefined T period, determines, if so, whether the display unit is in a connected state and, in if so, it controls display unit 130 to move items to positions at a predefined distance from their previous position. If it is determined that display unit 130 is in the off state when the counter reaches the T period, item shift unit 142 determines whether a display on command is entered via input unit 120 and, if so, controls display unit 130 to display items in positions at a predefined distance from their previous positions.
    [0048] If a display power command is entered in the display unit's off state, the item displacement unit 142 can control the display of some of the items in the positions at a predefined range from their previous positions in the display unit 130. The item displacement unit 142 can also control the display unit 130 in such a way that the items are moved one by one or group by groups, each including two items, in a predefined order.
    [0049] Items are classified in the first and second regions, and if a display on command is entered in the off state of display unit 130, item shift unit 142 controls the display of items from the first region in positions in one predefined interval from its previous positions and determines a cumulative number of on / off operations of the display unit 130. If it is determined that the cumulative number of on / off operations reaches a predefined K value, the item displacement unit 142 controls display unit 130 such that items in the second region are displayed in positions at a predefined range from their previous positions to the right before the display unit 130's off state and initializes the on / off operations counter to 0 .
    [0050] With the previous knowledge about the configuration of the display device described above, it is graphical user interface (GUI) to reduce the effect of image pasted on the display device below.
    [0051] Figure 3 is a flow chart illustrating a method for providing an interface for reducing an image effect pasted on a display device according to an exemplary embodiment of the present invention.
    [0052] With reference to figure 3, a control unit 140 monitors to detect a display on command introduced by input unit 120 in step 301. The user can enter the display on command by selecting an on / off key on the display device. display 100 or, in the case of using a touchscreen, by tapping an on / off key displayed on the touchscreen.
    [0053] If it is determined in step 301 that the display on command is entered via input unit 120, control unit 140 controls display unit 130 to display at least one item in a predefined position in step 302. The item is an image object that is changed at a relatively low frequency and can be the image object indicating information about the current state of the display device 100. The information about the current state of the display device 100 can be any of the intensity cell radio reception strength, Wi-Fi radio reception strength, current time, battery status, alarm setting, Bluetooth radio on / off status, and GPS on / off status.
    [0054] When display unit 130 displays at least one item, the control unit controls display unit 130 such that at least one item is arranged on a line in each predefined region of the screen. For example, control unit 140 can control display unit 130 to display items on a horizontal line in a region that has a predefined width.
    [0055] The display device 100 is configured with information about the positions of the items when the items are initially presented, and the control unit 140 controls the display unit 130 to display the items according to the information about the positions of the items in step 302.
    [0056] In step 303, the display on / off control unit 141 determines whether a display off command is entered via input unit 120. The user can enter the display off command by selecting the on key. on / off the display, provided on display device 100.
    [0057] If it is determined in step 303 that the display off command is entered via input unit 120, the display on / off control unit 141 is disconnected from display unit 130 in step 304.
    [0058] Thereafter, the display on / off control unit 141 monitors the display on command input in step 305, and if the display on command is entered, the display unit is turned on 130 and sends to the item displacement unit 142 a signal notifying the display unit 130 of power. If the ligation notification signal is received from the display on / off control unit 141, the item displacement unit 142 controls display unit 130 to display at least one item in positions at a predefined distance from previous positions prior to shutting down display unit 130 in step 306.
    [0059] The item displacement unit 142 exchanges all items as arranged. For example, when a plurality of items are arranged on a horizontal line, the item displacement unit 142 can move the items, as agreed, in a left or right direction by as much as a predefined distance. In addition, when a plurality of articles are arranged in a vertical line, the item displacement unit 142 can move the items as arranged upwardly or in a direction of unloading by as much as a predefined distance.
    [0060] The predefined distance can be one or two pixels. The item shifting unit 142 shifts items by as much as one or two pixels, and therefore it is difficult for the user to notice the shifting of items.
    [0061] The item shift unit 142 moves items along a predefined path. In an exemplary implementation, where items are arranged in a horizontal direction, item shifting unit 142 can shift items by one pixel in the two-pixel range to the left and right directions, whenever display unit 130 transitions from the off state to the on state. Assuming that the reference point is (0, 0) in the initial presentation of the items, the item displacement unit 142 can move the item to positions (-1, 0), (-2, 0), (0, 0 ), (1, 0), (2, 0), (1 0,), and (0, 0), in sequence.
    [0062] Whenever the display unit 130 transitions from the off state to the on state, the item shift unit 142 can shift items per pixel to the left, right, up, down directions in the range of 1 pixel. That is, assuming that the reference point is (0, 0) in the initial presentation of the items, the item displacement unit 142 can move the items to positions (-1, 0), (-1, -1), (0, -1), and (0, 0), in sequence.
    [0063] If the display off command is not detected in step 303, the display on / off control unit 141 determines whether a predetermined time has elapsed after the display of the items in step 307. If it is determined that the predetermined time took place in step 307, the display on / off control unit 141 turns display unit 130 off in step 304, and the display on / off control unit 131 and item shift unit 142 perform steps 305 and 306.
    [0064] Figure 4 illustrates the screen images to explain how to move items on a display device screen according to an exemplary embodiment of the present invention.
    [0065] Referring to part [a] of figure 4, it shows the screen with an indicator region 41 arranged at the top and which presents a plurality of items 42, 43, 44 and 45, indicating information about the current state of the display device 100. Indicator region 41 includes a cellular radio reception intensity indicator item 42, Wi-Fi radio reception intensity indicator item 43, current time indicator item 44, and a battery 45.
    [0066] Referring to part [b] of figure 4, it shows the screen presented when the display unit 130 transitions from the off state, as shown on the screen of part [a] of figure 4, to the on state. As shown in part [b] of figure 4, items 42, 43, 44, and 45 are shifted to the left by as much as a predefined distance 46 from the screen in part [a] of figure 4. In part [ b] of figure 4, the predefined distance can be one or two pixels.
    [0067] Figure 5 illustrates a pattern of displacement of items in an indicator region of a display device screen according to an exemplary embodiment of the present invention.
    [0068] With reference to figure 5, items 42, 43, 44 and 45 are shifted as far as a predefined distance whenever the display unit 130 transitions from the off state to the on state, for example, it shifts to the left twice , four times to the right, and twice to the left. Assuming that the predefined distance 46 is one pixel, items 42, 43, 44 and 45 are shifted 2 pixels to the left, 4 pixels to the right, and 2 pixels to the left in the 1 pixel unit. That is, assuming that the lower left point of the cell radio reception intensity indicator item 42 is (0, 0), this point moves to the points (-1, 0), (-2, 0), (0 , 0), (1, 0), (2, 0), (1, 0) and (0, 0) in sequence whenever the display unit 130 transitions from the off state to the on state.
    [0069] According to the exemplary embodiments shown in figures 3 to 5, when the display unit 130 transitions from the off state to the on state, the display device 100 shifts items exchanged at a relatively low frequency, as far as a predefined distance in order to prevent these items from being displayed in the same positions for an undesirable extended period of time, thus reducing the pasted image effect created. More particularly, the display device 100 moves the items in the minimum distance unit, i.e., one pixel, it is possible to maximize the efficiency of reducing the pasted image effect without the user's awareness of the displacements of the items.
    [0070] Figure 6 is a flow chart illustrating a method for providing an interface to reduce an image effect pasted on a display device according to an exemplary embodiment of the present invention.
    [0071] With reference to figure 6, a display device 100 displaces the positions of at least one item periodically. The control unit 140 controls the display unit 130 to display at least one item at a predefined position on the screen in step 601. The display device 100 has information about the initial positions of the items, and the control unit 140 controls the display unit 130 for displaying items in the initial positions in step 601. After displaying the items, item displacement unit 142 starts a timer to count the elapsed time.
    [0072] The item offset unit 142 determines whether the count reaches the T period predefined in step 602. If the count reaches the current T period, the item offset unit 142 determines whether the display unit 130 is, in the state connected in step 603 and, if so, controls display unit 130 to move at least one item on the screen, as far as a predefined distance, in step 604.
    [0073] If it is determined that display unit 130 is in the off state in step 603, item shift unit 142 determines whether a display on command is entered in step 605. If the user enters the display on command by through the input unit 120, the display on / off control unit 141 notifies the item shift unit 142 of the input of the display on command. Thereafter, the item displacement unit 142 controls the display unit 130 to move at least one item as much as the distance predefined in step 604. At this time, the item displacement unit 142 controls the display unit 130 to show the items in the far position from the previous right position before the off state, as far as the predefined distance. The item shifting operations described with reference to figures 4 and 5 can be applied to the exemplary embodiment of figure 6 in the same way.
    [0074] Figure 7 is a flow chart illustrating a method for providing an interface for reducing an image effect glued to a display device in accordance with an exemplary embodiment of the present invention.
    [0075] With reference to figure 7, the control unit 140 determines whether a display on command is entered via input unit 120 in step 701 and, if the display on command is entered, controls display unit 130 to display N items on the screen in step 702. The N items are sequence numbers assigned from 1 to N.
    [0076] The item displacement unit 142 defines the variables in 1 in step 703. Here, n indicates the sequence number of the item to be displaced, and the item displacement unit 142 selects the first item among the first to N -th item in step 703.
    [0077] The display on / off control unit 141 determines whether a display off command is entered via input unit 120 in step 704. If it is determined that the display off command is entered in step 704, the unit display on / off control unit 141 turns display unit 130 off in step 705.
    [0078] The display on / off control unit 141 then determines whether a display on command is received via input unit 120 in step 706. If it is determined that the display on command is entered in step 706, the display on / off control unit 141 turns on the display unit 130 and sends to the item displacement unit 142 a signal notifying you of the insertion of the display on command. Thereafter, if the signal is received from the display on / off control unit 141, the item shift unit 142 controls the display unit 130 to move the nth item to a position far from the previous right position before the off state of display unit 130, as much as the distance predefined in step 707. In a case that n is set to 1, item shift unit 142 controls display unit 130 to shift the first item on the screen.
    [0079] The item displacement unit 142 moves the items one by one. In an exemplary implementation, where the items are arranged in a horizontal line, the item shifting unit 142 shifts the items in sequence from the most left, to the left.
    [0080] The item displacement unit 142 can move items according to a predefined path. In an exemplary implementation where items are arranged in a horizontal direction, item shift unit 142 shifts items in sequence from the left most to the right towards the left and from the most right to the most left in one direction to the right, whenever the display unit 130 transitions from the off state to the on state. At this point, the distance between two points is maintained without overlapping with each other, after the items are moved.
    [0081] Thereafter, the item displacement unit 142 determines whether n is equal to N in step 708. If n is equal to N, the item displacement unit 142 initializes n to 1, in step 703 so that the display on / off control unit 141 and item shift unit 142 perform steps 704-707.
    [0082] If n is not equal to N in step 708, the displacement unit of item 142 sets n to n + 1 in step 709 so that the display on / off control unit 141 and the displacement unit of item 142 perform steps 704-707.
    [0083] If it is determined that the display off command is not entered in step 704, the display on / off control unit 141 determines whether a predefined time has elapsed after the items have been displayed in step 710. If the predefined time has elapsed, the display on / off control unit 141 turns display unit 130 off at step 705 so that the display on / off control unit 141 and item shift unit 142 perform the steps 706 and 707.
    [0084] Although the display device 100 shifts the items, in order from the first item to the N-shift and shifts the items in the same order for the next shift cycle in the embodiment of figure 7, the present invention is not limited to same, but items can be moved in order from the first to the Nth item for the first travel cycle and in reverse order for the next travel cycle.
    [0085] Although the display device 100 moves items one by one in the exemplary embodiment of figure 7, the present invention is not limited to this, the display device 100 can be configured to move items in the unit of a group that includes two or more items.
    [0086] Figure 8 illustrates screen images to explain how to move items on a display device screen according to an exemplary embodiment of the present invention.
    [0087] With reference to figure 8, as part [a] of figure 4, part [a] of figure 8 shows a screen with an indicator region 41 arranged at the top and which presents a plurality of items 42, 43, 44 and 45, indicating information about the current state of the display device 100. The indicator region 41 includes the cell radio reception intensity indicator item 42, the Wi-Fi radio reception intensity indicator item 43, the indicator item current time 44, and a battery indicator item 45.
    [0088] Part [b] of figure 8 shows the screen presented when the display unit 130 transitions from the off state, as shown on the screen of part [a] of figure 8, to the on state. In part [b] of figure 8, the cell radio reception intensity indicator item 42 is shifted to the left as far as a predefined distance 46 in the indicator region 41 from the screen in part [a] of figure 8 while other items 43, 44, 45 and maintain their positions as in part [a] of figure 8.
    [0089] Part [c] of figure 8 shows the screen shown when the display unit 130 transitions from the on state, as shown on the screen of part [b] of figure 8, to the off state. In part [c] of figure 8, the Wi-Fi radio intensity indicator item 43 is shifted to the left as far as the preset distance 46 as compared to the screen in part [b] of figure 8, while other items 42, 44, and 45 maintain their positions as in part [b] of figure 8.
    [0090] In the exemplary embodiments of figures 7 and 8, once one or some of the items, instead of all, are moved, it is possible to reduce the effect of pasted image efficiently, minimizing the variation of the presentation on the screen.
    [0091] Figure 9 is a flow chart illustrating a method for providing an interface for reducing an image effect pasted on a display device according to an exemplary embodiment of the present invention.
    [0092] With reference to figure 9, the items are distributed to a plurality of regions, in order to be moved by region.
    [0093] Control unit 140 determines whether a connected screen command is entered via input unit 120 in step 901 and, if the display on command is entered, controls display unit 130 to display at least one item of a predefined position in the respective first and second regions in step 902.
    [0094] The items displayed in the first region are the image objects that are changed at a relatively low frequency among all the image objects presented in the display unit 130 and can be an image object that provide information about the current state of the display device display 100. Information about the current status of the display device 100 can be any of the intensity of cellular radio reception, the intensity of Wi-Fi radio reception, the current time, the battery status, the alarm setting , the on / off state of the Bluetooth radio, and the on / off state of the GPS.
    [0095] The items displayed in the second region are the objects in the image that change at a relatively high frequency compared to those shown in the first region, but at a low frequency, compared to normal application icons, and can be a little icons of frequently used applications, such as a phone icon, a message icon, an Internet browser icon, and so on.
    [0096] The display on / off control unit 141 determines whether a display off command is entered via input unit 120 at step 903. If it is determined that the display off command is entered at step 903, the display on / off control unit 141 turns display unit 130 off in step 904.
    [0097] The display on / off control unit 141 then determines whether a display on / off command is entered in step 905 and, if the display on / off command is entered, the display unit is turned on 130 and sends the signal displacement unit 142 the signal notifying the input of the command to turn on the display. If the display on command is received from display on / off control unit 141, item shift unit 142 controls display unit 130 to show at least one item, in the first region, in positions as far as a predefined distance from the original positions in step 906. The item shift operations described with reference to figure 3 can also be applied to the exemplary embodiment of figure 9 in the same way.
    [0098] Thereafter, item displacement unit 142 determines whether the cumulative number of on / off operations of display unit 130 reaches a predefined K value in step 907, where K is a period for moving items in the second region.
    [0099] If it is determined that the cumulative number of on / off operations of the display unit 130 reaches the value of K, in step 907, the item displacement unit 142 displaces at least one item in the second region, as much as the predefined distance from its home position to the right before display unit 130 turns off, on display screen 130 in step 908. Item shift unit 142 then starts the on operation counter / off to 0 in step 909.
    [0100] If it is determined that the display off command is not entered in step 903, the display on / off control unit 141 determines whether a predetermined time has elapsed after the items have been displayed in step 910. If the predetermined time has elapsed, the display on / off control unit 141 turns display unit 130 off at step 904 so that the display on / off control unit 141 and item shift unit 142 perform steps 905 and 909.
    [0101] Although the description in figure 9 was directed to the case where the items are shown in two regions, the present invention is not limited to this and can be applied to the case where the items can be displayed in three or more regions .
    [0102] Figure 10 illustrates screen images to explain how to move items on a display device screen according to an exemplary embodiment of the present invention.
    [0103] With reference to figure 10, which shows the screens displayed on a mobile communication terminal. The part [a] of figure 10 shows a screen with the first region 41 positioned at the top and which presents a plurality of items 42, 43, 44, and 45 and the second region 51 positioned at the bottom and which presents an item of telephone 52, a contact item 53, a message item 54, and a menu item 55. The first region 41 includes a cell radio reception strength indicator item 42, a Wi-Fi radio reception strength indicator item 43, the current time indicator item 44, and a battery indicator item 45.
    [0104] Part [b] of figure 10 shows the screen shown when the display unit 130 transitions from the off state, as shown on the screen of part [a] of figure 19, to the on state. In part [b] of figure 10, items 42, 43, 44 and 45 of the first region 41 are shifted to the left, as far as a predefined distance from their original positions in part [a] of figure 10, and the items 52, 53, 54 and 55 of the second region 51 maintain their original positions.
    [0105] Part [c] of figure 10 shows the screen displayed when the display unit 130 transitions from the off state, as shown on the screen of part [b] of figure 10, to the on state. In part [c] of figure 10, items 42, 43, 44, and 45 of the first region 41 are shifted to the left, as far as the predefined distance 46 as compared to part [b] of figure 10, and items 52 , 53, 54, and 55 of the second region 51 are shifted to the left as far as a predefined distance 56 as compared to part [b] of figure 10.
    [0106] In figure 10, the items that belonged to the first region 41 are shifted in each on / off operation of the screen, and the items that belonged to the second region 51 are shifted every two on / off operations on the display.
    [0107] In the exemplary embodiments of figures 9 and 10, the items are moved at different times according to the frequency of alteration of the presentation of the items, in order to improve the efficiency of reducing the effect of pasted image with minimum displacement operations of the items. items displayed on the screen.
    [0108] In the exemplary embodiments of figures 9 and 10, the term "sub-region" indicates a region on the display device that has a width that is less than twice the width of one of the items. The first region and the second region are examples of the sub-region.
    [0109] As described above, the display device of the present invention shifts the position of a specific image whenever the viewfinder is turned on in order to reduce the glued image effect caused when displaying a still image, for an extended period of time undesirable. That is, the display device blurs the outline of the phantom image by adjusting the position of a specific image, thus prolonging the time required for the user to perceive the phantom image.
    [0110] In exemplary embodiments of the present invention, since the position shift is done finely in units of one or two pixels, it is difficult for the user to perceive the position shift of the image with the naked eye, which results in the improvement of efficiency of reducing the effect of pasted image.
    [0111] Although the invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in shape and details can be made therein without departing from the spirit and scope of the invention as defined by the attached claims and their equivalents.
