Description of the Prior Art The advancement of semiconductor manufacturing technology has rapidly evolved display devices from the early-day display screens to touch-enabled devices and small touch-sensitive devices. to existing personal mobile devices, enabling mobile devices to support people in all moments of life and to be used around the world to enhance convenience and entertainment in everyday life.
    Conventional touch devices have been widely applied to all areas, including public equipment and transportation tools. Usually, public equipment has more stringent weather requirements than private equipment, especially for outdoor use, because touch devices sometimes become impossible to control due to temperature variation. A countermeasure against weather is to fix a film forming a window on a touch assembly. The touch assembly is constituted by a display and a tactile detection layer. Despite the protection afforded by the window film, after a period of operation, the touch assembly tends to be sensitive to environmental conditions, such as ultraviolet light. Environmental conditions accelerate aging of the film forming a window and the touch assembly. After long exposure to sunlight and wind and various types of users' operating habits, the window film is subject to damage and peeling, and the original protection function is diminished or even disappeared totally.
    An object of the present invention is to provide a tactile device with a reinforced protective effect on it able to improve the durability and the operating cycle of the touch device.
    To achieve the above objective, the tactile device with enhanced protection effect on it comprises a touch assembly, at least one protective layer, and a transparent layer.

Said at least one protective layer consists of a transparent and anti-ultraviolet material. The transparent layer has a high hardness. Since the protective layer is sandwiched between the transparent layer and the touch assembly, and is not sensitive to an aging effect resulting from environmental factors, the durability and productivity of the touch device can be effectively improved.
    According to another aspect of the invention, the tactile assembly comprises a display and a tactile detection layer.
    According to another aspect of the invention, the tactile device further comprises a transparent substrate arranged between the display and the tactile detection layer.
    According to another aspect of the invention, the tactile device further comprises a thermal shielding layer which is vacuum-fitted and thermally insulating, arranged between the transparent substrate and the tactile sensing layer, and having a clearance space. insulation defined within the heat shield layer, the insulation adhesive being applied around a perimeter of the heat shield layer.
    According to another aspect of the invention, the heat shield layer further comprises a plurality of point spacers arranged inside the insulation space, regularly spaced from each other, and made of a transparent material; and the isolation space is depressurized by a vacuum depressing process through an opening formed through a portion of the insulating adhesive and communicating with the insulation space, and the insulating adhesive is filled in the vacuum insulation space so that the heat shield layer is aspirated and thermally insulated.
    According to another aspect of the invention, a thickness of each one protective layer is greater than or equal to 300 μτη.
    According to another aspect of the invention, the transparent layer is formed by a reinforced glass capable of transmitting light.
    According to another aspect of the invention, the transparent substrate is formed by a glass substrate or a transparent and resilient material.

    DESCRIPTION OF THE DRAWINGS
    FIG. 1 is a schematic view, from the side and in section, of a first embodiment of a tactile device with a reinforced protective effect on it, according to the present invention; Figure 2 is a schematic side view in section of a second embodiment of a touch device with a reinforced protective effect on it, according to the present invention; Figure 3 is a schematic side view in section of the tactile device of Figure 2 when a transparent layer and a tactile detection layer are not implemented on the touch device; and FIG. 4 is a diagrammatic, side and sectional view of the tactile device of FIG. 2 when a transparent layer and a tactile detection layer are set up on the touch device.
    As can be seen in FIG. 1, a first embodiment of a tactile device with a reinforced protective effect on it in accordance with the present invention comprises a touch assembly, at least one protective layer 10, and a transparent layer 20. Said device at least one protective layer 10 is provided on the touch assembly. The transparent layer 20 is arranged on said at least one protective layer 10. In the present embodiment, the tactile assembly comprises a display 30 and a tactile detection layer 40. The layer 40 of tactile detection is arranged on the display 30, the said at least one protective layer 10 is arranged on the layer 40 of tactile detection and the transparent layer 20 is stuck on the protective layer 10, so that the Touch device can be built accordingly. The transparent layer 20 may be made of reinforced glass capable of transmitting light. The protective layer 10 may be arranged by uniformly applying a binding agent mixed with titanium dioxide nanoparticles (TiCL), or zinc oxide nanoparticles (ZnO), on the tactile detection layer 40. Since titanium dioxide nanoparticles or zinc oxide nanoparticles can absorb ultraviolet light, an aging effect caused by ultraviolet radiation on the touch device can be effectively reduced. The binding agent is transparent to light.
    The protective layer 10 is a laminated structure arranged on the layer 40 of tactile detection. In order to improve a protective effect of the protective layer 10, multiple protective layers 10 may be provided on the tactile detection layer 40. In the present embodiment, the thickness of each protective layer 10 is greater than or equal to 300 μτη. Since the protective layer 10 is provided by the bonding agent, an elongation rate of each protective layer 10 is in the range of 200% to 300%. The protective layer 10 is used for protection purposes. When the protective layer 10 is actuated at an ambient temperature of 25 ° C, a tensile strength of the protective layer 10 at the yield strength of 200 mm / min can reach a range from 200 kg / cm 2 to 300 kg / cm2.
    As can be seen in FIG. 2, a second embodiment of a tactile device with a reinforced protection effect on it according to the present invention differs from the first embodiment by a transparent substrate 50 arranged between the display 30 and the layer 40 of tactile detection, and a layer 60 forming a heat shield arranged between the transparent substrate 50 and the layer 40 of tactile detection. In the present embodiment, the transparent substrate 50 is provided by a glass substrate or a resilient material capable of transmitting light.
    With regard to the manner in which the heat shield layer 60 is prepared, with reference to FIGS. 3 and 4, the transparent substrate 50 is arranged on the display 30, a layer of polymer film is painted on the transparent substrate 50 and the layer 60 forming a heat shield comprises a plurality of point spacers 61 arranged on the transparent substrate 50, regularly spaced apart from each other by interstices, and manufactured by forming the multiple point spacers 61 inside the polymer film by a screen printing process or a photolithography process. The multiple point spacers 61 serve to improve the support capacity of the touch device. A portion of the polymer film not occupied by the multiple point spacers 61 is etched to form an insulating gap 64. An insulating adhesive 62 is applied to a perimeter of the heat shield layer 60. An opening 63 is formed through the insulating adhesive at a portion of the perimeter of the heat shield layer 60 to communicate with the insulating space 64 in the heat shield layer 60, so that insulating space 64 may be The insulating adhesive 62 is further filled in the insulating space 64 so that the layer 60 forming the heat shield is depressurized and thermally insulated. In the present embodiment, the multiple point spacers 61 are made of a transparent material. The manner of preparing point spacers 61 in the present embodiment is applicable to large touch devices. In the case of small tactile devices, the multiple point spacers 61 of the layer 60 forming a heat shield are not necessarily prepared.
    As furthermore visible in FIGS. 2 and 4, an insulating space 64 in the layer 60 forming a heat shield not occupied by the multiple point spacers 61 is depressed by the depressurization process, so that the insulating space Vacuum is filled with the insulating adhesive 62 through the opening 63 to form the vacuum heat shield layer 60. The protective layer 10 is arranged on the layer 40 of tactile detection and the transparent layer 20 is arranged on the protective layer 10.
