Abstract
Description
Technical Field
[0001] This utility model relates to the field of display technology, and more specifically, to a touch screen that improves display brightness. Background Technology
[0002] To improve the brightness of traditional LCD screens, the design of the backlight module is usually carried out, such as increasing the number or power of LEDs, or adding a brightness enhancement film in the optical film module. However, increasing the number or power of LEDs will inevitably lead to increased costs, increased power consumption, and a large amount of heat dissipation. If a brightness enhancement film is added to the optical film module, there is a limit to the brightness improvement. It is difficult to further increase the brightness in an optical film module that already has a brightness enhancement film. Utility Model Content
[0003] The technical problem this invention aims to solve is how to improve the display brightness of a touchscreen without increasing power consumption or significantly raising product costs.
[0004] The technical problem to be solved by this utility model is achieved through the following technical solution:
[0005] To address the aforementioned technical problems, this utility model provides a touchscreen for enhancing display brightness, comprising a cover plate. A background pattern ink layer is disposed on the lower surface of the cover plate in the non-visible area. An acrylic resin gloss-enhancing coating is disposed on the lower surface of the cover plate in the visible area. The acrylic resin gloss-enhancing coating has prism-patterned sawtooth or wavy acrylic resin microstructures. A high-thickness OCA coating is disposed on the lower surface of the acrylic resin gloss-enhancing coating, completely covering the acrylic resin gloss-enhancing coating and extending to the lower surface of the background pattern ink layer. A touch film is adhered below the high-thickness OCA coating, and an FPC is led out from one end of the touch film. The thickness of the high-thickness OCA coating is 4 to 6 times the thickness of the acrylic resin gloss-enhancing coating.
[0006] As a preferred embodiment of the touch screen with improved display brightness provided by this utility model, the thickness of the high-thickness OCA coating is 0.1mm-0.25mm, and the thickness of the acrylic resin gloss-enhancing coating is 0.02mm-0.06mm.
[0007] In a preferred embodiment of the touch screen with enhanced display brightness provided by this utility model, the thickness of the high-thickness OCA coating is 5 times the thickness of the acrylic resin gloss-enhancing coating.
[0008] As a preferred embodiment of the touch screen that enhances display brightness provided by this utility model, the cover plate is provided with an anti-fingerprint film.
[0009] As a preferred embodiment of the touch screen that enhances display brightness provided by this utility model, the thickness of the anti-fingerprint film is 1μm to 10μm.
[0010] As a preferred embodiment of the touch screen that enhances display brightness provided by this utility model, the upper surface of the cover plate located in the non-visible area is provided with a surface treatment layer that enhances surface roughness.
[0011] In a preferred embodiment of the touch screen that enhances display brightness provided by this utility model, the surface treatment layer is a frosted layer.
[0012] In a preferred embodiment of the touch screen with improved display brightness provided by this utility model, the surface treatment layer is an etched layer.
[0013] As a preferred embodiment of the touch screen that enhances display brightness provided by this utility model, an adhesive layer is provided on the lower surface of the anti-fingerprint film located in the non-visible area.
[0014] In a preferred embodiment of the touch screen that enhances display brightness provided by this utility model, the thickness of the adhesive layer is 0.5 μm.
[0015] This utility model has the following beneficial effects:
[0016] Because the lower surface of the cover plate in the visible area is provided with an acrylic resin brightness enhancement coating, which has a prism-patterned sawtooth or wavy acrylic resin microstructure, the function of the acrylic resin brightness enhancement coating is to change the direction of light to achieve a light-gathering effect, thereby increasing brightness. Theoretically, it can increase brightness by about 60% in a single direction. The thickness of the high-thickness OCA coating between the touch film and the cover plate is 4 to 6 times that of the acrylic resin brightness enhancement coating, so as to absorb the coating step difference and reduce the risk of bubble formation. This structure flexibly integrates the brightness enhancement film application on the display screen into the touch screen cover plate, and covers it with a high-thickness OCA coating. The acrylic resin brightness enhancement coating wrapped between the cover plate and the high-thickness OCA coating is well protected from wear, and the display effect of the touch screen is greatly enhanced. This greatly improves the screen brightness and clarity of the display module with this structure, optimizes the optical performance of the display module, and thus improves the display brightness of the touch screen without increasing power consumption or significantly increasing product cost.

[0027] Because the lower surface of the cover plate in the visible area is provided with an acrylic resin brightness enhancement coating, which has a prism-patterned sawtooth or wavy acrylic resin microstructure, the function of the acrylic resin brightness enhancement coating is to change the direction of light to achieve a light-gathering effect, thereby increasing brightness. Theoretically, it can increase brightness by about 60% in a single direction. The thickness of the high-thickness OCA coating between the touch film and the cover plate is 4 to 6 times that of the acrylic resin brightness enhancement coating, so as to absorb the coating step difference and reduce the risk of bubble formation. This structure flexibly integrates the brightness enhancement film application on the display screen into the touch screen cover plate, and covers it with a high-thickness OCA coating.
