Technical Field

[0001] The utility model relates to screen protection technology, and in particular to a screen cover plate. Background Art

[0002] A screen cover plate is a transparent lens that fits outside a display screen and is used to protect the display screens of touch display modules and non-touch display modules. It has functions such as scratch resistance, drop resistance, and fingerprint resistance. According to the material of the cover plate substrate, screen cover plates can be mainly divided into glass cover plates, ceramic cover plates, plastic cover plates, and optical composite material cover plates. Among them, glass cover plates are widely used due to their excellent performance.

[0003] In addition to the protection function, as the outermost device of the display screen, the screen cover plate also has an aesthetic function to enhance the overall aesthetics of electronic products and make them more in line with the aesthetic needs of consumers. However, existing screen cover plates generally provide appearance by coating colored ink on the border area, with monotonous colors and a single visual effect, making it difficult to meet the growing personalized needs of electronic devices.

[0027] Embodiment 1

[0028] As Figure 1 and 2 shown, a screen cover plate with a silver starry sky flash effect includes:

[0029] A cover plate substrate 10, including a display area 11 and a border area 12, and the border area 12 surrounds the display area 11.

[0030] Dense silver metal spots 20 are provided on the back surface of the cover plate substrate 10 and are only distributed in the border area 12. The spot diameter is 0.10 - 0.15 mm, and the distribution pitch is 0.5 - 1.5 mm;

[0031] Black covering ink 30 is provided on the surface of the silver metal spots 20 away from the cover plate substrate 10 and only covers each silver metal spot 20 and the border area 12 exposed between the silver metal spots 20.

[0032] In the screen cover plate of the present utility model, dense silver metal spots 20 are skillfully distributed on the back surface of the cover plate substrate 10 and are limited to the border area 12. Such a layout will neither interfere with the display effect of the display area 11 nor create a unique visual effect at the border. The spot diameter of the silver metal spots 20 is 0.10 - 0.15 mm, and the distribution pitch is 0.5 - 1.5 mm. This fine size control ensures the density and uniform distribution of the spots, thus forming a delicate starry sky flashing effect, making each silver metal spot 20 produce a flashing effect under the illumination of light, simulating the twinkling of stars in the night sky and bringing a romantic and mysterious visual enjoyment to users; while the black covering ink 30 provides a black night sky background for the silver metal spots 20, making the whole look more unified and harmonious.

[0033] The silver metal spots 20 can be made on the frame area of the cover plate substrate 10 by screen printing with a metal mixture or metal paste (such as silver paste), or a metal film layer (such as a chromium film layer) can be first formed on the back surface of the cover plate substrate 10, and then the metal film layer can be etched by laser.

[0034] In this embodiment, the thickness of the silver metal spots 20 is 20 - 50 nm, and the silver metal spots 20 can be but are not limited to chromium metal spots 20 or silver metal spots 20.

[0035] In this embodiment, the thickness of the black covering ink 30 is 3 - 8 μm.

[0036] Embodiment Two

[0037] As an optimized solution of Embodiment One, in this embodiment, as Figure 3 shown, the screen cover plate further includes a silicon dioxide film 40 with a thickness of 50 - 100 nm, which is provided on the front surface of the cover plate substrate 10 and covers both the display area 11 and the border area 12 at the same time.

[0038] The silica film 40, as the innermost film on the front surface of the cover substrate 10, mainly serves to improve the adhesion ability between the cover substrate 10 and other films, preventing other films from peeling off the cover substrate. Additionally, the silica film 40 can also protect the cover substrate 10, preventing it from coming into direct contact with chemical substances in the external environment, thereby enhancing its corrosion resistance and wear resistance. At the same time, the silica film 40 also has a certain optical transparency and does not affect the display effect of the display area 11.

[0039] Preferably, the screen cover further includes a titanium nitride film 50 with a thickness of 100 - 200 nm, which is disposed on the surface of the silica film 40 away from the cover substrate 10 and simultaneously covers the display area 11 and the border area 12.

[0040] The titanium nitride film 50 has excellent hardness and wear resistance, which can further enhance the scratch resistance of the screen cover. At the same time, it also improves the surface hardness and corrosion resistance of the screen cover, protecting the silica film 40 from damage.

[0041] Preferably, the screen cover further includes a titanium diboride film 60 with a thickness of 200 - 300 nm, which is disposed on the surface of the titanium nitride film 50 away from the silica film 40 and simultaneously covers the display area 11 and the border area 12.

[0042] The titanium diboride film 60 has excellent thermal conductivity, which can effectively disperse the heat generated during the use of the screen and maintain the stable operation of the screen. In addition, it can also provide a certain degree of hardness and wear resistance, further enhancing the overall performance of the screen cover.

[0043] Preferably, the screen cover further includes an alumina film 70 with a thickness of 300 - 500 nm, which is disposed on the surface of the titanium diboride film 60 away from the titanium nitride film 50 and simultaneously covers the display area 11 and the border area 12.

[0044] The alumina film 70 is a material with high hardness and high wear resistance, which can significantly improve the scratch resistance and wear resistance of the screen cover. At the same time, it also has excellent insulation performance and chemical stability, protecting the internal electronic components of the screen from the influence of the external environment.

[0045] Preferably, the screen cover further includes a silicon nitride film 80 with a thickness of 200 - 400 nm, which is disposed on the surface of the alumina film 70 away from the titanium diboride film 60 and simultaneously covers the display area 11 and the border area 12.

[0046] The silicon nitride film 80 has good thermal stability and chemical stability, and can further protect the screen cover plate from high temperature and chemical substances. At the same time, it can also provide a certain hardness and wear resistance, enhancing the overall durability of the screen cover plate.

[0047] Preferably, the screen cover plate further includes a niobium pentoxide film 90 with a thickness of 100 - 200 nm, which is disposed on the surface of the silicon nitride film 80 away from the alumina film 70 and simultaneously covers the display area 11 and the border area 12.

[0048] The niobium pentoxide film 90 is a material with a high refractive index, which can enhance the optical performance of the screen cover plate, such as improving the brightness and contrast of the screen. In addition, it also has excellent ultraviolet resistance and can absorb ultraviolet rays to protect the internal devices of the screen from ultraviolet damage.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention and are not intended to limit them. Although the embodiments of the present invention have been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the embodiments of the present invention can still be modified or equivalently replaced, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
