[0002] With the increasing popularity of electronic display devices and the growing demand for advanced functions, traditional glass covers can no longer meet users' comprehensive requirements for aesthetics, durability, and multifunctionality. Therefore, there is a need to develop a unique and feature-rich cover coating. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional composite coated glass cover and a display module containing it, which aims to improve the wear resistance, corrosion resistance, conductivity and visual effect of the cover to meet the growing quality and functional requirements of electronic products.

[0004] Specifically, the technical solution of this utility model is as follows: a multifunctional composite coated glass cover is proposed, comprising a glass substrate and a composite coated structure on both its front and back sides, wherein: the front coated structure comprises, from the outside to the inside:

[0005] The gold-palladium alloy layer has a thickness of 5–10 nm; the chromium-nickel alloy layer has a thickness of 10–20 nm; and the samarium oxide coating layer has a thickness of 5–10 nm.

[0006] The back coating structure, from the outside to the inside, includes: a photosensitive color-changing ink screen printing layer with a thickness of 4-5 μm, containing a polymer matrix containing spiropyran derivatives; a titanium oxide layer with a thickness of 10-20 nm, having an anatase crystal structure; and a titanium-aluminum alloy layer with a thickness of 20-30 nm.

[0007] The glass cover has asymmetrically arranged latching grooves at the center of its four opposite sides. The latching grooves have an inverted "L" shape in cross-section. Correspondingly, the backlight part of the display module has latches. When assembled, the latching grooves and latches cooperate with each other to form an assembly.

[0008] As a preferred technical solution, a chamfered structure is provided at the edge of the slot opening of the buckle groove, so that the buckle can slide into the buckle groove along the chamfered structure during assembly.

[0009] As a preferred technical solution, the buckle groove is located at the middle of the thickness of the glass cover plate.

[0010] As a preferred technical solution, the surface roughness Ra of the gold-palladium alloy layer is ≤0.8nm, the Vickers hardness of the chromium-nickel alloy layer is ≥800HV, and the transmittance of the samarium oxide coating layer in the visible light band is ≥98%.

[0011] As a preferred technical solution, the gold-palladium alloy layer is prepared by magnetron sputtering to form a face-centered cubic structure with a preferred orientation.

[0012] As a preferred technical solution, the screen printing layer of the photosensitive color-changing ink contains a nano zinc oxide photosensitizer with a particle size of 20-50 nm.

[0013] As a preferred technical solution, the color change response wavelength of the photosensitive color-changing ink screen printing layer is 300–450 nm, and it responds to ultraviolet radiation intensity of 0.5–1.5 mW / cm². 2 Under these conditions, the color switching time is ≤15 seconds and the color difference ΔE is ≥40.

[0014] As a preferred technical solution, the titanium oxide layer is prepared by atomic layer deposition.

[0015] As a preferred technical solution, its comprehensive performance meets the following requirements: visible light transmittance ≥92%, hardness ≥9H, and color switching response time ≤20 seconds.

[0016] On the other hand, a display module is also proposed, including a display screen and a backlight, and a multifunctional composite coated glass cover as described above; wherein, the backlight is provided with a buckle, and the buckle groove engages with the buckle to assemble the multifunctional composite coated glass cover with the display module.

[0017] The beneficial effects of this utility model are: the glass cover plate of this utility model is provided with a snap-fit ​​groove, which is correspondingly matched with the snap-fit ​​of the backlight for assembly. With this setting, there is no need for optical adhesive to bond the cover plate and the backlight, thus reducing costs; moreover, it is easy to disassemble during assembly and repair.

[0018] On the other hand, based on the principle of layered coating, the integration and optimization of multiple functions are achieved by precisely controlling the thickness and position of each material layer. The gold-palladium alloy layer provides conductivity and corrosion resistance; the chromium-nickel alloy and titanium-aluminum alloy layers enhance wear resistance; the samarium oxide and titanium oxide layers ensure high light transmittance and chemical stability; and the photosensitive color-changing ink screen printing layers give the cover a unique visual effect. The synergistic interaction of each material layer not only improves the service life and aesthetics of the cover but also meets diverse needs such as electromagnetic shielding. This invention, through its carefully designed coating structure and material selection, provides electronic devices with a high-quality, aesthetically pleasing, and durable protective barrier, achieving a dual improvement in technological innovation and user experience.
