Frequently Asked Questions
Professional guidance to support your problem-solving
How do I choose the right LGP thickness?
The right thickness depends on the panel size, LED arrangement, structure limitations, and brightness target. Thinner is not always better.
Why is light uniformity so important?
Uniformity affects both visual quality and product performance. A bright panel with visible hot spots or dark zones usually does not create a good user experience.
What materials are commonly used for LGPs?
Optical-grade PMMA is one of the most commonly used materials, although other transparent materials may also be selected depending on the application.
Is an LGP the same as a diffuser plate?
No. A light guide plate is designed to guide and extract light, while a diffuser is mainly used to soften and spread the light after it exits the optical system.
What does LGP stand for?
LGP stands for Light Guide Plate. It is an optical panel used to distribute LED light evenly across a surface.
