Description

Technical Field

[0001] This application relates to the field of glass cover technology, and in particular to a coated glass cover, a display screen, and electronic equipment. Background Technology

[0002] A glass cover is a transparent lens used to protect a display screen. It is attached to the outside of an electronic display screen and mainly serves to protect the screen. Glass covers have good light transmittance and a special texture, which can enhance surface hardness and toughness, and provide better protection.

[0003] With the rapid development of technology, glass covers have been widely used in fields such as electronic displays, solar energy products, and automotive displays due to their high transparency, excellent mechanical properties, and good chemical stability.

[0004] In existing technologies, to enable glass cover plates to possess certain functions, a functional film layer is often coated onto the glass cover plate to form a coated glass cover plate. However, while existing coated glass cover plates used in displays can possess certain functionalities, they suffer from weak adhesion between the coated film layer and the glass cover plate, resulting in poor stability. Furthermore, existing coated glass cover plates do not simultaneously meet the display's requirements for both protective performance and optical performance. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a coated glass cover, a display screen, and an electronic device that balances the protective performance and optical performance requirements of the display screen for the cover, while improving the adhesion between the coating and the glass cover.

[0006] To achieve the above objectives, this application provides a coated glass cover plate, including a glass substrate, wherein the front side of the glass substrate is coated with a coating layer, and the coating layer includes an adhesion enhancement layer, an optical functional layer and a protective layer coated sequentially from bottom to top.

[0007] As a further optimization of the coated glass cover provided by this utility model, the thickness of the adhesion enhancement layer is 10nm~900nm.

[0008] As a further optimization of the coated glass cover provided by this utility model, the adhesion enhancement layer includes a sodium oxide layer.

[0009] As a further optimization of the coated glass cover provided by this utility model, the optical functional layer includes an AgCl layer.

[0010] As a further optimization of the coated glass cover provided by this utility model, the thickness of the optical functional layer is 200nm~300nm.

[0011] As a further optimization of the coated glass cover provided by this utility model, the protective layer includes a TiC layer.

[0012] As a further optimization of the coated glass cover provided by this utility model, the thickness of the protective layer is 500nm~700nm.

[0013] As a further optimization of the coated glass cover provided by this utility model, the two corners of the glass substrate at the top are rounded.

[0014] To achieve the above objectives, this application also provides a display screen, including the coated glass cover as described above.

[0015] To achieve the above objectives, this application also provides an electronic device, including a coated glass cover as described above, or a display screen as described above.

[0016] The coated glass cover plate of this application has the following beneficial effects:

[0017] The coated glass cover of this application is provided with an adhesion enhancement layer, which enhances the adhesion between the coating layer and the glass substrate and improves the stability and durability of the coating layer.

[0018] The coated glass cover of this application has an optical performance layer that can provide a reflective coating effect, reduce glare, and enhance UV resistance.

[0031] One embodiment of this application provides a coated glass cover that balances the protective performance and optical performance requirements of the display screen, while improving the adhesion between the coating and the glass cover.

[0032] The following will refer to Figures 1-2 The coated glass cover of this application is described in detail, such as... Figure 1-2 As shown, the coated glass cover of this application includes:

[0033] Glass substrate 1;

[0034] The front side of the glass substrate 1 is coated with a coating layer, which includes an adhesion enhancement layer 2, an optical functional layer 3, and a protective layer 4 coated sequentially from bottom to top.

[0035] In this embodiment, the adhesion enhancement layer 2 is a sodium oxide layer, and the thickness of the adhesion enhancement layer 2 is 10 nm to 900 nm. The Na2O in the sodium oxide layer has good chemical compatibility with the SiO2 in the glass, which can enhance the adhesion between the coating layer and the glass substrate.

[0036] In this embodiment, the optical functional layer 3 is an AgCl layer with a thickness of 200nm~300nm. AgCl can be used to adjust the reflectivity of light, provide a reflective coating effect, reduce glare, and enhance UV resistance.

[0037] In this embodiment, the protective layer 4 includes a TiC layer with a thickness of 500 nm to 700 nm. TiC is a material with high hardness, high wear resistance, and good chemical stability. The TiC layer can protect the internal AgCl layer from external environmental corrosion, such as oxidation and scratches. This increases the hardness and wear resistance of the coated glass cover, and improves the scratch resistance and chemical stability of the coating layer.
