Description

Technical Field

[0001] The utility model relates to the technical field of displays, in particular to a CTP cover plate assembly, a display screen and a display module. Background Art

[0002] CTP refers to a capacitive touch screen. At present, the cover plates of capacitive touch screens with cover plates are often transparent. In order to reduce ambient light interference and improve the visibility of the picture, an AG (Anti-Graffiti) coating is sprayed on the viewing area of the cover plate surface. The AG coating can make the glass surface rough, forming a matte non-reflective surface, thereby reducing the amount of specular reflected light entering the human eye and achieving an anti-glare effect. Since the AG coating is exposed on the surface layer of the cover plate, during the use of the display product, the AG coating is likely to fall off due to factors such as sunlight, rain, and scratching, resulting in the failure of the AG function. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the utility model provides a CTP cover plate assembly, a display screen and a display module, aiming to neither affect the TP touch function nor avoid the AG coating on the top layer of the cover plate from being worn and falling off.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A CTP cover plate assembly includes a cover plate, an ink layer, a conductive layer, and an AG coating, which are arranged in sequence from top to bottom;

[0006] The ink layer is attached to the four peripheral edges of the back of the cover plate for surrounding the viewing area;

[0007] The upper side of the conductive layer is connected to the cover plate through a first OCA layer, and the AG coating is provided on the lower side of the conductive layer.

[0008] A further technical solution is:

[0009] The conductive layer includes colorless transparent glass and an ITO thin film or nano silver wire provided on the colorless transparent glass.

[0010] A display screen includes the CTP cover plate assembly and a backlight assembly, and the AG coating is connected to the backlight assembly through a second OCA layer.

[0011] A further technical solution is:

[0012] The backlight assembly includes a backlight, a first polarizer, a TFT glass, and a second polarizer, which are arranged in sequence from bottom to top, and the second polarizer is connected to the AG coating through the second OCA layer.

[0013] The second polarizer, the TFT glass, and the first polarizer are stacked in the backlight. Bending portions are formed at both ends of the backlight, and part of the bending portions cover the edges of the second polarizer.

[0014] The top surface of the bending portion is connected to the AG coating through the second OCA layer.

[0015] The conductive layer, the AG coating, and the backlight assembly have the same width, and are smaller than the width of the cover plate.

[0016] The widths of the first OCA layer and the second OCA layer are the same as the width of the conductive layer.

[0017] The cover plate is transparent colorless tempered glass; the ink layer is black ink.

[0018] A display module includes the display screen described above.

[0019] The beneficial effects of the present utility model are as follows:

[0020] In the present utility model, the AG coating is sprayed on the bottom of the ITO glass of the CTP cover plate assembly, which neither affects the use of the TP touch function nor causes the AG coating to be worn and peeled off on the outermost layer of the cover plate. Those skilled in the art can understand that the function of the AG coating is to improve the visibility of the display screen image, so as long as it is in the upper area of the display TFT, therefore, the technical solution of the present utility model is feasible. It does not affect the functions of the display screen and the display module, and at the same time can prevent the AG coating from being worn and peeled off, ensuring the anti-glare effect of the display screen.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following describes the specific embodiments of the present utility model with reference to the drawings.

[0025] As Figure 1 shown, this embodiment provides a CTP cover plate assembly, including a cover plate 1, an ink layer 2, a conductive layer, and an AG coating 6 arranged in sequence from top to bottom;

[0026] The ink layer 2 is attached to the four peripheral edges on the back of the cover plate 1 for enclosing the viewing area;

[0027] The upper side of the conductive layer is connected to the cover plate 1 through a first OCA layer 3 (Optically Clear Adhesive), and an AG coating 6 is provided on the lower side of the conductive layer.

[0028] The conductive layer includes a colorless transparent glass 5 and an ITO thin film (indium tin oxide thin film) or nano silver wire 4 provided on the colorless transparent glass 5.

[0029] This embodiment also provides a display screen, including the CTP cover plate assembly and a backlight assembly, and the AG coating 6 is connected to the backlight assembly through a second OCA layer 7.

[0030] The backlight assembly includes a backlight 8, a first polarizer 11, a TFT glass 10 (Thin - Film Transistor), and a second polarizer 9 arranged in sequence from bottom to top. The second polarizer 9 is connected to the AG coating 6 through a second OCA layer 7.

[0031] The second polarizer 9, the TFT glass 10, and the first polarizer 11 are stacked in the backlight 8. Bending portions 81 are formed at both ends of the backlight 8, and part of the bending portions 81 covers the edge of the second polarizer 9. The bending portions 81 strengthen the firmness of the display screen structure and are also more dust - proof.

[0032] The top surface of the bending portion 81 is connected to the AG coating 6 through a second OCA layer 7.

[0033] The main function of the second polarizer 9 is to convert the light emitted by the backlight source into polarized light in a specific direction. Through its special filtering effect, the first polarizer 11 allows only the light with the polarization direction perpendicular to the plane to pass through, thus providing a basis for subsequent liquid crystal modulation and imaging.

[0034] Specifically, the widths of the conductive layer, the AG coating 6, and the backlight assembly are the same and smaller than the width of the cover plate 1.

[0035] Specifically, the widths of the first OCA layer 3 and the second OCA layer 7 are the same as the width of the conductive layer.

[0036] Specifically, both the first OCA layer 3 and the second OCA layer 7 are transparent colorless optical adhesives.

[0037] Specifically, the cover plate 1 is a transparent colorless tempered glass;

[0038] Specifically, the ink layer 2 is a black ink.

[0039] For the display screen of this embodiment, the AG coating is sprayed on the bottom of the ITO glass of the CTP cover plate assembly, which neither affects the use of the TP touch function nor causes the AG coating to wear and fall off on the outermost layer of the cover plate. Those skilled in the art can understand that the function of the AG coating is to improve the visibility of the display screen of the display, so it can be in the upper area above the display TFT. Therefore, the technical solution of the present invention is feasible.

[0040] This embodiment also provides a display module, including the above-mentioned display screen.

[0041] Those of ordinary skill in the art can understand that the above description is only the preferred embodiment of the present invention and is not intended to limit the present invention.
