TECHNICAL FIELD

[0001] The utility model relates to toughened glass film technical field, specifically to a kind of high-definition toughened glass film. BACKGROUND

[0002] With the wide popularity of electronic devices such as smartphones, tablets, laptops, etc. and the increasing demand for visual experience, the clarity of screen display has become a key performance indicator. Traditional tempered glass films mainly focus on the protection of the screen, preventing scratches, collisions and other physical damage, but there are many shortcomings in optical performance.

[0003] In terms of light propagation, ordinary tempered glass films, due to their smooth surface and unoptimized optical performance, can produce strong specular reflection when light shines on the screen, especially in outdoor bright light environments, the screen reflects light seriously, making it difficult for users to see the screen content, which greatly affects the convenience of use and visual effect of electronic devices. In addition, the diffusion ability of traditional tempered glass films for screen light is limited, making the screen have poor brightness and color uniformity when viewed at different angles, with a narrow viewing angle. When viewing the screen from the side, color distortion and brightness reduction may occur, which cannot meet the requirements of screen display effect when multiple people watch the screen at the same time or users use the device in different postures.

[0004] To solve these problems, some existing technologies try to add a single anti-reflection coating or a simple frosted layer to the tempered glass film to improve optical performance. However, relying solely on anti-reflection coating often cannot effectively solve the problem of glare, while a simple frosted layer can reduce reflection to some extent, but it also leads to a decrease in light transmittance and an unsatisfactory light diffusion effect, which cannot comprehensively improve the clarity and visual effect of the screen in various environments.

[0005] Therefore, it is necessary to propose an improved technical solution to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0027] Please refer to Figs. 1-2The utility model discloses an embodiment of a kind of high-definition toughened glass film, including toughened glass film body 1, the toughened glass film body 1 includes high transmittance toughened glass base layer 2, the toughened glass base layer 2 has opposite first surface and second surface, anti-glare layer 4 and anti-reflection coating 3 are sequentially arranged on the first surface of the toughened glass base layer 2, and the surface of the anti-glare layer 4 has microscopic frosted structure 5;

[0028] A layer of nanometer light diffusion layer 6 is arranged on the second surface of the toughened glass base layer 2, and a layer of optical coupling layer 7 is further arranged between the nanometer light diffusion layer 6 and the toughened glass base layer 2.

[0029] Among them:

[0030] The anti-reflection coating 3 is formed by alternately stacking oxide thin films with different refractive indexes;

[0031] The anti-glare layer 4 is made of fluoride glass material, and the frosted structure 5 on the surface of the anti-glare layer 4 is irregular microscopic concave-convex structure;

[0032] The nanometer light diffusion layer 6 is made of organic silicone resin doped with fluorescent quantum dots 8, and the fluorescent quantum dots 8 are uniformly distributed;

[0033] The optical coupling layer 7 is made of transparent polymer.

[0034] In the technical scheme of the utility model, the anti-reflection coating 3 is formed by alternately stacking oxide thin films with different refractive indexes. When light from the outside is incident on the toughened glass film, the light first contacts the anti-reflection coating 3. At the interface of each oxide thin film, the light propagates according to the laws of refraction and reflection. Part of the light is reflected back to the original medium, and another part of the light is refracted into the next layer of oxide thin film. Due to the different refractive indexes of the oxide thin films, the thickness and refractive index of each thin film are precisely controlled to make the light reflected at different interfaces interfere with each other. When the specific interference condition is met, the intensity of the reflected light in a certain wavelength range will cancel each other out, thereby allowing more light to pass through the coating. Ultimately, the purpose of improving the overall light transmittance of the toughened glass film is achieved. For example, in the common optical thin film interference principle, when the optical path difference of the two reflected lights is an odd multiple of half the wavelength, destructive interference occurs, the reflected light is reduced, and the amount of transmitted light is increased.

[0035] The anti-glare layer 4 is made of fluoride glass material, which has good optical transparency and chemical stability and is suitable for tempered glass film exposed to the outside environment for a long time. In the manufacturing process (such as chemical etching), the surface is treated into an irregular micro concave-convex structure. When light shines on this layer, the direction of light propagation will change on the micro concave-convex surface. The light originally propagating according to the law of specular reflection will be reflected and refracted multiple times at these concave-convex places and scattered in different directions. In this way, the original concentrated specular reflection is changed into diffuse reflection. Therefore, in the environment of strong light and other environments prone to glare, the reflected light of the screen is no longer strong and dazzling, but is evenly dispersed, thereby effectively reducing the glare phenomenon and improving the screen visibility.

[0036] The nano light diffusion layer 6 uses organic silicone resin as the base material and uniformly dopes fluorescent quantum dots 8. After the light emitted by the screen enters this layer, the fluorescent quantum dots 8 will absorb part of the light energy by virtue of their optical properties and then re-emit light at different angles. The uniform distribution of numerous quantum dots in the organic silicone resin makes the light continuously scattered and redistributed in the entire nano light diffusion layer 6, achieving uniform light diffusion. The organic silicone resin not only provides a stable physical support and dispersion environment for the quantum dots, but also has its own optical properties that can assist light propagation. The synergistic effect of the two improves the brightness and color uniformity of the screen when viewed from different angles and widens the viewing angle range.

[0037] The optical coupling layer 7 is made of transparent polymer. The key is that its refractive index matches that of the adjacent nano light diffusion layer 6 and tempered glass base layer 2. When light propagates in different media, refraction and reflection occur at the interface due to the difference in refractive index. Without the optical coupling layer 7, when light is transmitted from the nano light diffusion layer 6 to the tempered glass base layer 2, there will be significant reflection loss at the interface, resulting in inefficient light transmission. However, the optical coupling layer 7 plays a role in transition and connection. Because its refractive index is matched, light can relatively smoothly enter the tempered glass base layer 2 from the nano light diffusion layer 6, reducing reflection at the interface and maximizing the continuity of light transmission between layers, thereby improving light transmission efficiency.

[0038] In summary, the anti-reflection coating 3 effectively suppresses light reflection based on the thin film interference principle, allowing more light to pass through the tempered glass film to the user's eyes, making the displayed images, text, and other content on the screen clearer and sharper, with higher color reproduction and more vibrant colors. Users can clearly see the fine details on the screen, greatly improving the visual experience, especially in indoor and other conventional light environments.

[0039] The fluoride glass material of the anti-glare layer 4 and its unique irregular micro-concave-convex structure convert the mirror reflection which is easy to cause visual interference into diffuse reflection, so that the reflection of the screen surface is significantly weakened in various scenes where glare is easy to occur, such as outdoor strong light direct irradiation, indoor strong light irradiation, etc., and the user can easily and comfortably see the content displayed on the screen, and is no longer affected by the light spot and reflection of the strong light, thereby greatly improving the actual use effect of the electronic device under different illumination conditions.

[0040] The fluorescent quantum dots 8 uniformly distributed in the nano light diffusion layer 6 fully play a diffusion role on light, so that the brightness and color uniformity of the screen can be maintained at a good level when viewed at different angles, and the display effect of the screen can basically remain consistent in the case of multi-angle viewing of the screen such as multi-person sitting to watch videos or display content, or different postures such as lying or turning the body when using the device, thereby effectively avoiding the color deviation and brightness drop when viewing the screen from the side, widening the visible angle range of the screen, and enhancing the universality of the viewing experience.

[0041] The optical coupling layer 7 not only ensures the light transmission efficiency, but also enhances the physical connection tightness between the nano light diffusion layer 6 and the tempered glass base layer 2, so that the internal structure of the entire tempered glass film is more stable, and is not easy to separate or peel off between layers in the case of slight collision, friction or temperature change in daily use, thereby ensuring that the product can stably play its optical and other performances for a long time, prolonging the service life of the product, and reducing the replacement frequency of the user.

[0042] In the embodiment of the utility model, the outermost layer of the anti-reflection coating 3 is coated with a self-cleaning coating 9, and the self-cleaning coating 9 is composed of nano titanium dioxide and fluorocarbon polymer.

[0043] The self-cleaning coating 9 is composed of nano titanium dioxide and fluorocarbon polymer, the nano titanium dioxide has photocatalytic properties, and under light conditions, especially under ultraviolet irradiation, free radicals with strong oxidizing properties are generated on its surface, these free radicals can decompose organic matter, so that the organic stains such as oil stains and fingerprints on the surface of the coating are oxidized and decomposed into small molecular substances, thereby separating from the surface of the coating, achieving the effect of self-cleaning, at the same time, the fluorocarbon polymer has the property of low surface energy, which makes water unable to spread on the surface of the coating, but form water droplets and roll off, and the water droplets can carry away the particulate matter such as dust on the surface of the coating during the rolling process, further enhancing the cleaning effect and keeping the surface of the coating clean; thereby effectively avoiding the problems of screen blurring and poor display effect caused by the accumulation of fingerprints and oil stains, and always presenting a clear screen picture to the user.

[0044] In this embodiment of the present invention, a black light-blocking frame 10 is provided at the edge of the tempered glass film body 1.

[0045] The black light-blocking bezel 10 is typically made of a high-polymer material with good light absorption properties. Its design principle is based on the principle of light absorption and blocking. When external light shines on the tempered glass film, due to the difference in refractive index between the screen and the edge of the film, as well as the refraction and reflection characteristics of light, some light will enter from the edge of the film and be scattered inside, thus affecting the contrast and visual effect of the screen display, especially in strong light environments. The black light-blocking bezel 10 utilizes its high light absorption performance to absorb light entering from the edge to the maximum extent, reduce the reflection and scattering of light within the film, and prevent light from leaking into the screen display area, thereby providing the screen with a relatively stable and pure light display environment.

[0046] In this embodiment of the present invention, a silicone adsorption layer 11 is also provided on the surface of the nano-light diffusion layer 6 away from the tempered glass base layer 2.

[0047] The silicone adsorption layer 11 mainly utilizes the adhesive properties of silicone material to achieve a tight fit between this high-definition tempered glass film and the screen.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
