[0029] The specific embodiment of the utility model is described below in combination with the drawings.

[0030] Referring to Figure 1 and Figure 2 , the combined double-layer structure glass cover plate of the embodiment includes a cover plate body and a fixing member 6, the cover plate body includes a composite coating layer, an upper glass substrate 4 and a lower glass substrate 5 which are sequentially stacked, and the fixing member 6 is arranged on the outer side of the cover plate body to tightly fix the upper glass substrate 4 and the lower glass substrate 5.

[0031] The surface of the lower glass substrate 5 is provided with a microstructure 501 which is used to reduce reflectivity; the composite coating layer includes an adhesive layer 3, an anti-reflection film layer 2 and a wear-resistant layer 1 which are sequentially stacked, and the adhesive layer 3 is located on the surface of the upper glass substrate 4.

[0032] As a specific embodiment, the fixing member 6 is a plastic frame which is sleeved on the outer periphery of the cover plate body. Referring to Figure 3 , the plastic frame is similar to a rubber band and binds the upper and lower glass substrates tightly. Therefore, it is not necessary to set an adhesive layer between the two, which ensures the penetration effect of light on the interface between the two and is convenient for disassembly, maintenance and replacement. The elastic coefficient and specific material of the plastic frame are set according to actual requirements. The size of the plastic frame is preferably the side surface of the upper and lower glass substrates which is completely wrapped.

[0033] As a preferred embodiment, the upper and lower side edges of the plastic frame are respectively provided with frames 601 which extend inward and are respectively used to wrap the front edge of the upper glass substrate 4 and the back edge of the lower glass substrate 5.

[0034] As a specific embodiment, the adhesive layer 3 is a samarium oxide film layer with a thickness of 50-100 nanometers. Samarium oxide (Sm2O3) as a bottom layer provides good adhesion and thermal stability, which helps to enhance the bonding force between the coating layer and the glass substrate and prevent the coating layer from falling off during use. It can also improve the overall durability of the coating layer to a certain extent and make it more resistant to external environmental erosion.

[0035] As a specific embodiment, the anti-reflection film layer 2 is a titanium oxide film layer, and the thickness is 150-200 nanometers. Titanium oxide (TiO2) is a key material for achieving high-efficiency anti-reflection effect. By precisely controlling the thickness, the embodiment significantly reduces the reflection loss of light on the glass surface and improves the light transmittance.

[0036] As a specific embodiment, the wear-resistant layer 1 is a samarium fluoride film layer, and the thickness is 50-100 nanometers. Samarium fluoride (SmF3) has a positive effect on the mechanical properties such as hardness and wear resistance of the film layer, and improves the scratch resistance and wear resistance of the cover plate.

[0037] Specifically, each film layer can be formed by using existing film forming processes, such as sputtering film forming, evaporation film forming, etc.

[0038] The layered structure design of the composite film layer of the embodiment not only maximizes the use of the functions of each layer of material, but also further optimizes the overall performance of the film layer by precisely controlling the thickness of each layer, so as to meet the high-performance and multi-functional requirements of the glass cover plate in different modern industrial application scenarios.

[0039] Specifically, the microstructure 501 is formed on the surface of the lower glass substrate 5 by etching. The thickness of the microstructure 501 is 1-2 micrometers.

[0040] The microstructure 501 formed by etching has the characteristics of unevenness, which can reduce the reflectivity of the glass surface and thus reduce glare. Since the microstructure is on the surface of the lower glass substrate, it is at a certain distance from the surface of the upper glass, and does not affect the clarity.

[0041] The thickness of the upper glass substrate 4 is 1.1-2 millimeters.

[0042] The thickness of the lower glass substrate 5 is 1.1-2 millimeters.

[0043] The embodiment also provides a display module comprising the combined double-layer structure glass cover plate. The display module can be used in various devices with display functions, such as mobile phones, tablet computers, vehicle-mounted display screens, etc.

[0044] Those skilled in the art can understand that the above description is only a preferred embodiment of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
