[0002] At present, the ink layer on the existing display module cover is very easy to be scratched off, or the high temperature in the display module will also cause the ink layer to be melted by the high temperature, which will cause the ink area on the glass substrate to gradually disappear after years of use, thereby affecting the display of the display area of ​​the display module. Therefore, a display module glass cover structure is designed, which can form a hard, heat-resistant, weather-resistant, and chemical-resistant ink layer on the glass, thereby preventing the ink layer from being scratched off or corroded by high temperature or other conditions.

[0025] like Figure 1-2As shown, a display module glass cover structure includes: AF coating 1, AG coating 2, AR coating 3, glass substrate 4, first light-shielding ink 5 and second light-shielding ink 6; the back of the glass substrate 4 is screen-printed with the first light-shielding ink 5, and the back of the first light-shielding ink 5 is screen-printed with the second light-shielding ink 6; the surface of the glass substrate 4 is provided with AR coating 3, AG coating 2 and AF coating 1. It should be noted that the glass substrate 4 needs to be softened in production. Since the cooling speed of the glass surface is inconsistent with the cooling speed of the inside of the glass, the glass is in a state of internal tension and external compression, and compressive stress is formed on the surface to improve its strength, thereby forming tempered glass.

[0026] like Figure 1-2 As shown, in one embodiment, the first light-shielding ink layer 5 and the second light-shielding ink layer 6 are both screen-printed on the glass substrate 4 by physical tempering. It should be noted that the first light-shielding ink layer 5 and the second light-shielding ink layer 6 are sintered at high temperature together with the plain glass of the glass substrate 4 to be firmly fused together.

[0027] like Figure 1-2 As shown, in one embodiment, a visible area and an ink area are provided on the glass substrate 4, wherein the center of the glass substrate 4 is the visible area and occupies 80% to 85% of its total area, and the ink area surrounds the visible area in the center of the glass substrate 4 and occupies 15% to 20% of the total area. It should be noted that the shape of the front side of the visible area is generally the same as the shape of the front side of the glass substrate 4.

[0028] like Figure 1-2 As shown, in one embodiment, the AR coating 3, the AG coating 2 and the AF coating 1 are coated on the surface of the glass substrate 4 layer by layer in this order. The shape and size of the front of the AF coating 1 are the same as the shape and size of the surface of the glass substrate 4, and the AF coating 1 is an anti-fingerprint coating. The shape and size of the front of the AG coating 2 are the same as the shape and size of the surface of the glass substrate 4, and the AG coating 2 is an anti-glare coating. The shape of the front of the glass substrate 4 is square, and the glass substrate 4 is tempered glass. It should be noted that the AR coating 3 can reduce the reflection efficiency of the cover plate, and the shape and size of the front of the AR coating 3 are the same as the shape and size of the surface of the glass substrate 4.

[0029] like Figure 1-2 As shown, in one embodiment, the first layer of light-shielding ink 5 is screen-printed on the back of the ink layer of the glass substrate 4, and the first layer of light-shielding ink 5 is 0.2 mm to 0.5 mm inward relative to the outer shape of the glass substrate 4, and the first layer of light-shielding ink 5 is high-temperature ceramic ink. It should be noted that this design allows the ink to be firmly fused with the glass, and the ink layer surrounds the entire display module to surround it.

It should be noted that this design allows the ink layer to not affect the normal display of the visible area.

[0031] like Figure 1-2 As shown, in one embodiment, the colors of the first light-shielding ink layer 5 and the second light-shielding ink layer 6 are black. It should be noted that the colors of the first light-shielding ink layer 5 and the second light-shielding ink layer 6 can be not only black but also darker colors such as yellow or green.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
