Products Description
1. Product Introduction
Light Guide Plate (LGP) is a key component that effectively converts linear light sources into uniform surface light through complex and sophisticated optical design. It is widely used in liquid crystal displays (LCDs), lighting backlights, smart device screens, flat panel displays, and various smart lighting systems, playing a core role in ensuring uniform light distribution and improving display effects.
LGP is usually made of high-quality materials such as optical-grade PMMA (polymethyl methacrylate, also known as acrylic) or polycarbonate (PC) with high light transmittance. These materials have excellent optical transparency and heat resistance, and can maintain stable performance during long-term use. During the production process, advanced technologies such as laser engraving, UV printing, and etching printing are used to form tiny light guide points or light guide lines on the bottom of the plate. These microstructures can effectively guide light to propagate along a specific path, achieve efficient light transmission and scattering, and thus obtain uniform and soft surface light.
In addition, the design of the light guide plate has multiple advantages: its structure is light and thin, which can greatly reduce the size of the device, meeting the needs of modern devices for light and thin design; it is energy-saving and environmentally friendly, because its efficient light utilization reduces energy waste; at the same time, the design is flexible, and the shape and distribution of the microstructure can be adjusted according to different application requirements to achieve a variety of optical effects.
With the continuous development of display technology and lighting needs, light guide plates play an increasingly important role in improving display effects, reducing energy consumption, simplifying manufacturing processes, and achieving more innovative visual experiences. In the future, with the continuous advancement of material research and manufacturing processes, light guide plates will also have higher optical efficiency, more excellent environmental adaptability and richer design possibilities.

FAQ
1: How to choose PMMA and PC light guide plates? What are the differences between the two?
Answer: PMMA has a higher light transmittance (≥92%) and accurate color reproduction, which is suitable for high-end display scenarios (such as LCD screen backlight); PC has stronger impact resistance and high temperature resistance up to 120°C, which is suitable for harsh environments such as vehicle-mounted and outdoor lighting. We provide free material selection suggestions. Contact the technical team immediately to customize the best solution according to your application scenario.
2: Can ultra-thin/special-shaped light guide plates be customized? What is the minimum thickness and processing accuracy?
Answer: Support! We have laser engraving and precision injection molding technology, which can mass-produce 0.3mm ultra-thin light guide plates, and the processing accuracy of special-shaped structures (circular/wavy/hollow design) is ±0.05mm. Provide free 3D drawing review service, click to submit the requirements, and get a feasibility assessment report within 24 hours.
3: How long is the mass production delivery time of light guide plates? Do you provide proofing services?
A: The delivery time for regular orders is 7-10 days, and we support rapid proofing (small batch trial production) within 72 hours.
