Technical Field
[0001] The utility model relates to a glass cover plate, and more precisely, to an enhanced coated glass cover plate. Background Art
[0002] With the continuous progress of technology, glass cover plates are increasingly widely used in fields such as electronic displays, optical instruments, and industrial equipment. However, traditional glass cover plates have problems such as high reflectivity, single optical properties, insufficient mechanical properties, and poor heat resistance.
[0003] Chinese invention patent document CN116573865A discloses a coating method for a glass cover plate, including: dividing tempered glass into multiple sub - glass regions according to a preset size; screen - printing ink around the lower surfaces of the multiple sub - glasses; coating a functional film on the upper surface of the tempered glass; screen - printing a protective film on the upper surface of the functional film; cutting the tempered glass to peel the multiple sub - glasses from the tempered glass; grinding and chamfering the sides of the sub - glasses; pasting tempered protective films on the non - sides of the sub - glasses; performing tempering treatment on the sides of the sub - glasses; tearing off the tempered protective films on the sub - glasses; and performing a cleaning treatment on the sub - glasses after tearing off the tempered protective films. Coating the functional film on the upper surface of the tempered glass includes an anti - fingerprint film layer. The protective film includes: a protective blue film, and the protective blue film includes a silicon - fluoroalkane surfactant. The functional film further includes: an anti - reflection film layer and / or an anti - glare film layer. The functional film includes an anti - fingerprint film layer, an anti - reflection film layer, and an anti - glare film layer. The anti - glare film layer is disposed on the upper surface of the tempered glass; the anti - reflection film layer is disposed on the upper surface of the anti - glare film layer; the anti - fingerprint film layer is disposed on the upper surface of the anti - reflection film layer. The size of the tempered protective film is larger than the non - side size of the sub - glass. The ink includes dark - colored ink. The dark - colored ink includes black ink.
[0004] Obviously, this patent divides tempered glass into multiple sub - glass regions according to a preset size; screen - prints ink around the lower surfaces of the multiple sub - glasses; coats a functional film on the upper surface of the tempered glass; screen - prints a protective film on the upper surface of the functional film; cuts the tempered glass to peel the multiple sub - glasses from the tempered glass; grinds and chamfers the sides of the sub - glasses; pastes tempered protective films on the non - sides of the sub - glasses; performs tempering treatment on the sides of the sub - glasses; tears off the tempered protective films on the sub - glasses; and performs a cleaning treatment on the sub - glasses after tearing off the tempered protective films. Through the technical solution of first coating and then cutting directly on the incoming whole - sheet tempered glass, it realizes the technical problem of easily solving the difficult coating of small - size glass cover plates. However, this structure is too complex and the process is complicated.
[0005] Chinese invention patent document CN116161872A discloses a multifunctional coated cover glass. Along the thickness direction of the coated cover glass, the coated cover glass sequentially includes a cover glass substrate, a SnO2 functional layer, a TiOX functional layer, and a Si1-A-BOANB functional layer; wherein, the refractive index of the cover glass substrate is 1.54-1.67; the crystal phases of the SnO2 functional layer and the TiOX functional layer are both rutile phases; in the TiOX functional layer, 1.85≤x≤1.90; in the Si1-A-BOANB functional layer, 0.50≤A≤0.57, 0.08≤B≤0.16. The refractive index of the TiOX functional layer is 2.4-2.6, the band gap width is 2.7-2.8 eV, and the thickness is 100-130 nm. The refractive index of the Si1-A-BOANB functional layer is 1.55-1.61, and the thickness is 80-100 nm.
[0006] Obviously, this patent effectively combines the heat treatment of the TiOX functional layer with the coating process of the Si1-A-BOANB functional layer, simplifies the product preparation process, shortens the preparation cycle, and thus achieves the purpose of improving production efficiency. However, this process is also too complex and costly. Summary of the Utility Model
