What is a Light guide plate?

A light guide plate (LGP) is a transparent, flat optical device used to spread light evenly. The light from a light source (typically LEDs) is directed into the light guide plate, where it undergoes multiple internal reflections to evenly distribute the light. The light source is positioned at one end of the plate, and the plate is used to spread the light uniformly. This technology is commonly used in thin displays and backlighting systems to achieve even brightness. Due to its thin and lightweight properties, it is widely used in mobile devices, televisions, and lighting equipment.

Application of Light guide plate

✅Thin Displays
Light guide plates are used in thin TVs and monitors to provide uniform backlighting, ensuring even brightness across the entire screen.
✅Lighting Systems
In LED backlighting systems, light guide plates help diffuse light efficiently, achieving uniform lighting.
✅Mobile Devices
Light guide plates are used in thin mobile devices such as smartphones and tablets, providing even brightness across the display.
