Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of material science, and in particular relates to a light guide plate with an anti-scratch microstructure. Background Art
[0002] The light guide plate is made of optical-grade acrylic / PC sheet, and then a high-tech material with extremely high refractive index and no light absorption is used. The light guide points are printed on the bottom of the optical-grade acrylic sheet by laser engraving, V-shaped cross grid engraving, and UV screen printing technology. The optical-grade acrylic sheet is used to absorb the light emitted from the lamp and stay on the surface of the optical-grade acrylic sheet. When the light hits each light guide point, the reflected light will diffuse to all angles, and then destroy the reflection condition and emit from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can emit light evenly. The purpose of the reflective sheet is to reflect the light exposed from the bottom back into the light guide plate to improve the efficiency of light use; under the condition of equal area luminous brightness, the luminous efficiency is high and the power consumption is low. The single-sided microstructure array light guide plate generally adopts the extrusion molding production process.
[0003] The existing light guide plates currently have poor scratch resistance and microstructure. Improper microstructure design or damage will lead to uneven light distribution, thereby reducing the brightness and uniformity of the display. It may cause hot spots on the screen to be too bright or dark areas to be too dark, affecting the viewing experience. Scratches or damage on the surface of the light guide plate will produce visible defects on the screen, such as bright or dark lines. These defects will distract users and reduce display quality.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0025] Example 1

[0027] Specifically, the material of the substrate layer 1 is polymethyl methacrylate, the thickness of the substrate layer 1 is one millimeter, the thickness of the microstructure layer 2 is ten micrometers, and the thickness of the anti-scratch layer 3 is five micrometers.
[0028] Further: the substrate layer 1 is the main structure of the light guide plate, providing the necessary mechanical strength and dimensional stability. Polymethyl methacrylate is a material with high transparency and excellent optical properties. It is suitable as a substrate for the light guide plate, providing support and protection for the entire light guide plate.
[0029] Specifically, the top of the anti-scratch layer 3 is coated with an antistatic layer 4, and the material of the antistatic layer 4 is tin oxide material.
[0030] Further: The main function of the antistatic layer 4 is to prevent static electricity accumulation and reduce the adsorption of dust and pollutants on the surface of the light guide plate, thereby maintaining its cleanliness and light transmittance. Tin oxide, as a conductive material, can provide good antistatic properties while maintaining a high light transmittance.
[0031] Specifically, the top of the antistatic layer 4 is coated with an anti-ultraviolet layer 5 , and the material of the anti-ultraviolet layer 5 is zinc oxide.
[0032] Further: The main function of the anti-ultraviolet layer 5 is to absorb or reflect ultraviolet rays to prevent ultraviolet rays from causing damage to the internal materials of the light guide plate, such as degradation or discoloration. Zinc oxide is a commonly used ultraviolet protection material, which can effectively block the penetration of ultraviolet rays and protect the light guide plate and its internal components from the influence of ultraviolet rays.
[0033] Specifically, the top of the anti-ultraviolet layer 5 is coated with a brightening layer 6, and the material of the brightening layer 6 is silicon dioxide.
[0034] Further: The brightening layer 6 is also called an anti-reflection film or a reflection enhancement layer. Its main function is to increase the reflectivity and transmittance of light, thereby enhancing the brightness and optical efficiency of the light guide plate. As a high refractive index material, silicon dioxide can achieve optimization of reflection and transmission of light of specific wavelengths and improve light utilization by precisely controlling its thickness and multi-layer structure design.
[0035] Specifically, adhesive layers 7 are attached to the outer sides of the left and right ends of the substrate layer 1 , the microstructure layer 2 , and the anti-scratch layer 3 . The adhesive layer 7 is made of acrylic material.
[0036] Furthermore: the main function of the adhesive layer 7 is to firmly bond the substrate layer 1 with the microstructure layer 2, the anti-scratch layer 3, the antistatic layer 4, the anti-ultraviolet layer 5 and the brightening layer 6 to ensure the stability and optical performance of the overall structure.
[0037] Specifically, the thickness of the antistatic layer 4 is 500 nanometers, the thickness of the anti-ultraviolet layer 5 is 10 micrometers, and the thickness of the brightening layer 6 is 10 micrometers.
[0038] Furthermore: the design and function of each layer cooperate with each other to ensure that the light guide plate has good optical performance, durability and reliability, and can achieve high efficiency and long life of the light guide plate in the display device.

By setting the anti-scratch layer 3, the device can effectively improve the brightness during use. The durability of the light guide plate can protect it from being easily scratched or damaged, especially when it comes into contact with keys, coins or other sharp objects in daily use. It ensures that the surface of the light guide plate remains clear and tidy, extending the service life of the product. Maintaining the smoothness of the light guide plate can ensure that the image and text display quality is not damaged and significantly reduce the occurrence of scratches. This is especially important for devices that require high-definition display, such as mobile phone screens, computer monitors and TV screens. By maintaining the smoothness of the light guide plate, the image and text display quality is not damaged, the user experience is guaranteed to the greatest extent, and the need and frequency of replacement or repair are reduced.
