Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As described in the background art, with the rapid development of display technology, the cover plate display module is increasingly widely used in the fields of cosmetics, advertising, etc. However, when the backlight of the traditional display module cover plate is not lit, its appearance is relatively single and lacks attractiveness. The mirror reflection layer structure of the existing panel uses a combination of a polarizer and a reflective film to form a mirror reflection effect. This structure not only increases the material cost, but also requires a film laminating process, which increases the complexity of the preparation process, reduces the production efficiency, increases the overall preparation cost of the cover plate, is not conducive to product competition, and the requirements for the coating layer on the surface of the cover plate are also increasing in the cover plate industry.

[0025] To solve this technical problem, the present utility model provides a mirror cover plate and a display device, which are applied in the field of display devices.

[0026] Specifically, please refer to Figures 1-3, the mirror cover plate 1 specifically includes a cover plate 1. On one surface of the cover plate 1, a mirror silver semi-transparent ink layer 2 and a light-shielding layer 3 are screen-printed in sequence. On the other surface of the cover plate 1, a base coating 4 and an anti-reflection layer 5 are provided in sequence.

[0027] The display device includes the above-mentioned mirror cover plate 1.

[0028] For the mirror cover plate 1 and the display device provided by the present utility model, a mirror silver semi-transparent ink layer 2 with a mirror effect is screen-printed on the surface of the cover plate 1, presenting a mirror effect when the backlight of the display device is not lit and presenting clear display content when lit. The light-shielding layer 3 is provided to effectively prevent scratching and light leakage phenomena. Moreover, by using the screen-printing method, the preparation is simple, facilitating batch processing, which can reduce production costs, improve production efficiency, enhance product competitiveness. And the base coating 4 and the anti-reflection layer 5 provided on the other surface of the cover plate 1 can optimize the optical performance of the glass cover plate 1, ensure that light can be efficiently transmitted, while reducing unnecessary reflection and scattering, and can also play a protective role to prevent damage such as scratches and contamination on the glass surface.

[0029] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings.

[0030] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0032] Please refer to Figures 1-3 , a mirror cover plate is provided, which includes a cover plate 1. The cover plate 1 covers the surface of the display screen of the display device, playing a role in protecting the display screen. On one surface of the cover plate 1, a mirror silver semi-transparent ink layer 2 and a light-shielding layer 3 are screen-printed in sequence. On the other surface of the cover plate 1, a base coating 4 and an anti-reflection layer 5 are provided in sequence.

[0033] The cover plate 1 is used in a display device. The cover plate 1 is made of a material with a high light transmittance. Specifically, the cover plate 1 can be made of transparent glass or can be prepared from a flexible transparent material, enabling the cover plate 1400 to be foldable, and thus can be applied to a flexible and foldable display module. It can be made of transparent, soft, and foldable materials such as UTG (Ultra Thin Glass), CPI (Colorless Polyimide), and PET (Polyethylene Terephthalate).

[0034] The mirror silver semi-transparent ink layer 2 is disposed on the back surface of the cover plate 1 and the mirror silver semi-transparent ink layer 2 covers the entire surface of the cover plate 1, enabling the entire outer surface of the cover plate 1 to present a mirror effect, achieving the mirror effect when the backlight is not lit and clear display when the backlight is lit, enhancing the aesthetics and practicality of the product. And the light-shielding layer 3 is disposed around the mirror silver semi-transparent ink layer 2. The light-shielding layer 3 functions to prevent scratching, block the backlight, and prevent light leakage, enhancing the durability and stability of the product. Further, the cover plate 1 includes a display area 101 and a non-display area 101. The light-shielding layer 3 is disposed in the non-display area 101, which can ensure the display effect and achieve a light-shielding effect during display.

[0035] The mirror silver semi-transparent ink layer 2 uses an ink with a special effect, which is a volatile drying ink that can achieve a mirror effect when viewed from the front. Its main components are metal powders (such as aluminum powder, silver powder) and transparent resin. By printing on the back of the transparent material and utilizing the principle of light interference, it presents a mirror effect on the front. Specifically, the mirror silver semi-transparent ink is composed of silver pigments, transparent bases, and other additives. The silver pigments give the ink a silver appearance, and the transparent bases are used to dilute and fix the pigments, enabling them to be evenly coated on the surface of the printed material. Other additives may include drying agents, stabilizers, etc. to improve the performance and stability of the ink.

[0036] The light-shielding layer 3 is a black ink layer, which is convenient to obtain materials, has a low cost, and has a good light-shielding effect.

[0037] During preparation, a layer of mirror silver semi-transparent ink layer 2 is screen-printed on the back surface of the cover plate 1 by screen printing. The thickness of the mirror silver semi-transparent ink layer 2 is 4 - 6 microns. When assembled into a display module, when the backlight is not lit, it looks like a mirror when viewed from the front. When the backlight is lit, the viewing area can display the content of the display screen, suitable for different makeup or advertising display products. Then, a layer of black ink layer is screen-printed on the surface of the mirror silver semi-transparent ink layer 2 to form the light-shielding layer 3. The screen-printed thickness of the black ink layer is 10 - 12 microns, which functions to prevent scratching of the silver semi-transparent ink layer, block the backlight, and prevent light leakage.

[0038] The base coating 4 and the anti-reflection layer 5 are deposited on the surface of the cover plate 1 by means of chemical vapor deposition, physical vapor deposition, sol-gel method, thermal spraying or electroplating, and can be independently selected according to the coating requirements. The above coating preparation methods are conventional existing technologies and will not be described separately here.

[0039] The base coating 4 is a methacryloxy silane layer with a thickness of 100 - 200 nanometers, which enhances the adhesion between the surface of the cover plate 1 and the subsequent coating layers, making the entire coating layer more durable and stable.

[0040] The anti-reflection layer 5 is a magnesium fluoride layer with a thickness of 100 - 200 nanometers, which can significantly reduce the reflection of light on the surface of the cover plate 1, increase the transmission of light, and thus improve the display effect and visibility.

[0041] The mirror cover plate provided in Example 1 is further optimized as Figure 1 shown. Specifically, an optical adjustment layer 6 is deposited on the surface of the anti-reflection layer 5. The optical adjustment layer 6 covers the anti-reflection layer 5. The optical adjustment layer 6 is a vanadium oxide layer with a thickness of 80 - 160 nanometers. The optical adjustment layer 6 is arranged on the outermost layer. When the temperature changes, the optical properties of vanadium oxide will change, thereby realizing dynamic adjustment of the transmission or reflection of light to adapt to different application scenarios such as makeup or billboards. Specific elements can also be doped into vanadium oxide, which can effectively adjust its phase change temperature and optical properties, thereby improving the color change effect. For example, doping tungsten (W): can lower the phase change temperature of vanadium dioxide, enabling it to change color near room temperature, expanding the actual application range. Vanadium oxide doped with tungsten can adjust the color more sensitively according to the change of environmental temperature, improving energy utilization efficiency. For example, doping molybdenum (Mo): can also have a positive impact on the phase change characteristics and color change of vanadium oxide. Vanadium oxide doped with molybdenum can show more obvious color differences at different temperatures.

[0042] As an optical adjustment layer, the vanadium oxide layer can realize dynamic adjustment of light, change the transmission or reflection of light according to environmental or user needs, and increase the intelligence and interactivity of the device. In cooperation with the base coating 4 and the anti-reflection layer 5, the overall coating layer optimizes the optical performance of the glass cover plate 1, ensures that light can be efficiently transmitted, while reducing unnecessary reflection and scattering. The coating layer can also provide a certain degree of protection to prevent damage to the glass surface such as scratches and contamination.

[0043] This embodiment provides a display device, which includes the mirror cover plate 1 in Example 1 or Example 2. The display device in the embodiments of the present application can be other electronic devices with display functions such as billboards, smart cosmetic boxes, dressing mirrors, tablet computers, e-readers, and smart phones.

[0044] The preparation method of the mirror cover plate provided by the present utility model is as follows: First, screen-print mirror silver semi-transparent ink on the back of the cover plate 1 to form a mirror silver semi-transparent ink layer 2, which can achieve the effect that when the backlight is not on during the assembly of the display module, it looks like a mirror from the front. When the backlight is lit, the viewing area can display the content of the display screen, so as to be suitable for different makeup or advertising display products. Then, screen-print border black ink on the second layer to form a light-shielding layer 3, which can prevent scratches, block the backlight and prevent light leakage. Finally, sequentially deposit a methacryloxy silane layer, a magnesium fluoride layer and a vanadium oxide layer on the front of the cover plate 1. The multi-layer coating structure on the front not only improves the optical performance of the cover plate 1, such as visibility and clarity, but also enhances the adhesion and durability of the coating through the methacryloxy silane layer. The magnesium fluoride layer effectively reduces the reflection of light and improves the display effect. The vanadium oxide layer can realize the dynamic adjustment of light according to needs, increasing the intelligence and interactivity of the product.
