Optimizing the design of PS Light Guide Panels (polystyrene light guide panels) to achieve better light distribution requires multiple aspects such as material selection, optical design, manufacturing process, and application environment. The following are specific optimization strategies and methods:

Dot pattern design
Key role: The dot pattern inside the light guide panel is the core of achieving uniform light distribution. These dots guide light from the edge light source to the entire panel through reflection and scattering.
Optimization method:
Reasonable distribution density: The dot density should gradually change according to the distance from the light source. The dot density is lower near the light source and higher at the distance from the light source to compensate for the phenomenon that the light intensity decreases with the propagation distance.
Shape and size adjustment: The shape (such as circle, ellipse or diamond) and size of the dots affect the scattering angle and range of light. Generally, larger dots produce wider scattering angles, which are suitable for improving the brightness of remote areas.
Computer simulation optimization: Use ray tracing software (such as TracePro or LightTools) to simulate and analyze the dot pattern to find the best design solution.
Light guide plate thickness and size
Thickness impact:
Thicker light guide plates can reduce light loss, but increase weight and cost.
Thinner light guide plates are more suitable for lightweight design, but may require higher dot accuracy to ensure light uniformity.
Optimization method:
Choose the appropriate thickness according to the specific application scenario. For example, a thinner light guide plate is used in small devices, while a thicker light guide plate is used in large backlight systems.

For ultra-thin designs, the problem of insufficient light uniformity can be compensated by improving the dot pattern or adding auxiliary optical films (such as diffusion films).
Edge processing
Key role: The edge of the light guide plate is the main channel for light to enter, and its processing quality directly affects the input efficiency and distribution effect of light.
Optimization method:
High-precision cutting: Use laser cutting or precision mold die-casting technology to ensure that the edge is smooth and flawless.
Mirror polishing: Polish the edges to improve the reflectivity of light and reduce energy loss.
Anti-light leakage design: Add sealing strips or shading materials to the edges to prevent light leakage.
Surface treatment
Key role: The surface quality of the light guide plate directly affects the transmittance and uniformity of light.
Optimization method:
Anti-glare coating: Apply an anti-glare layer on the surface of the light guide plate to reduce external light interference and improve the display effect.
Hard coating: Increase surface hardness, prevent scratches and wear, and extend service life.
Anti-UV coating: Protect the light guide plate from the effects of ultraviolet aging and maintain long-term performance stability.
Combination of optical films
Key role: A single light guide plate may not fully meet the needs of certain application scenarios. Combining optical films can further improve the light distribution effect.
Optimization method:
Diffusion film: Used to homogenize light output and eliminate local bright spots or dark areas.
Brightness enhancement film: Improve overall brightness by focusing light, suitable for occasions with high brightness requirements.
Reflective film: Installed on the back of the light guide plate, it reflects unused light back to the panel to improve light utilization.
Light source selection and layout
Key role: The type and layout of the light source directly affect the light input quality and distribution effect of the light guide plate.
Optimization method:
Select high-efficiency light source: Give priority to high-brightness, low-energy LED light sources to ensure sufficient and uniform light input.
Optimize the position of the light source: Arrange the position of the light source reasonably according to the size and shape of the light guide plate. For example, for a rectangular light guide plate, light sources can be set on two or four sides.
Light coupling design: Improve the coupling efficiency between the light source and the light guide plate through a special light coupling structure (such as a microprism or lens array).
Environmental adaptability design
Key role: The actual application environment of the light guide plate may affect its performance, so environmental factors need to be considered.
Optimization method:
Heat-resistant design: When used in a high temperature environment, you can choose modified PS materials or add heat dissipation structures to avoid deformation caused by thermal expansion.
Waterproof and moisture-proof design: When used in a humid environment, a waterproof coating can be applied to the surface of the light guide plate or a sealing device can be added.
UV-resistant design: When used outdoors or under strong ultraviolet rays, add UV-resistant stabilizers or coatings to prevent material aging.

Through scientific design methods and advanced manufacturing technologies, the optical performance of the light guide plate can be significantly improved to meet the needs of different application scenarios.
