To ensure the optical performance and display effect of PS Light Guide Panels in applications, it is crucial to control the surface finish, optical parameters and other key factors.

The surface finish of the light guide panel directly affects the efficiency and uniformity of light propagation. If the surface is rough or defective, the propagation of light will be scattered or refracted, resulting in uneven light sources, which will affect the display effect. Therefore, maintaining a high-quality surface finish is crucial to ensure uniform light propagation.
The surface finish of the light guide panel can be improved through different surface treatment technologies to ensure better light propagation. Common methods include:
Use a special polishing process to make the surface of the light guide panel smoother, reduce tiny bumps and reduce surface roughness. A high-gloss surface can reduce light scattering and improve light uniformity.
By laser etching tiny structures on the surface of the light guide panel, the surface micromorphology can be changed, the reflectivity of light can be increased, and uniform distribution can be ensured. Laser etching can achieve high-precision surface design to meet different optical requirements.
A special reflective or diffuse coating is applied to the surface of the light guide panel to enhance the optical performance of the light guide panel. In this way, the coating can help reflect light and promote uniform distribution, reducing light absorption.

In order to make the light of the light guide plate evenly distributed, microstructures (such as microlens arrays, microprism structures, etc.) are usually designed on the surface of the light guide plate. These microstructures achieve uniform light distribution by controlling the refraction, reflection and diffusion of light. The design of the microstructure requires precise control of its size, spacing, shape and angle to ensure that the light propagates in the expected manner.
By making a microlens array on the surface of the light guide plate, the light can be effectively guided and evenly distributed on the board surface. The microlens array avoids the concentration of straight light by refracting light, allowing the light to propagate more evenly.
The microprism structure can effectively reflect light in the desired direction and evenly illuminate the entire panel by dispersing the light source. This structure is often used in applications that require high light uniformity.
The design of surface textures (such as microtexture, micronization, sand grain, etc.) can affect the propagation path of light, improve the scattering characteristics of light, and enhance the uniformity of light. By optimizing the shape and distribution of the texture, the brightness uniformity of the light guide plate can be effectively improved and the brightness difference can be reduced.
The light-entering surface of the PS light guide plate (i.e., the surface of the light source contact surface) is one of the key parts that affect the performance of the light guide plate. In order to maximize the light transmission efficiency and uniformity of the light source, the design of the light-entering surface is usually optimized by the following methods:
By designing an appropriate incident angle, ensure that the light from the light source can enter the light guide plate evenly. Different incident angles can affect the propagation path of light in the light guide plate, so it is necessary to select the optimal incident angle according to specific needs during design.
Coating an anti-reflection film or a reflective film on the light-entering surface can reduce the reflection loss of the light source and improve the efficiency of light entry. In addition, the reflective coating can guide more light into the light guide plate and improve the light efficiency.

Through refined design and high-precision processing technology, the optical performance of the light guide plate can be effectively improved, ensuring that the light source is evenly distributed, thereby providing an excellent visual experience in various display devices.
