What is LGP sheet?
LGP 시트 stands for Light Guide Plate sheet.
Light Guide Plate (LGP sheet) is an optical-grade transparent acrylic sheet, usually made from PMMA, PS, or MS material with special laser-dot or line patterns on the surface.

LGP sheet how it works
- LEDs inject light into the edge of the LGP.
- Light travels inside the transparent sheet by total internal reflection.
- Special dot/line patterns on the sheet surface extract the light out evenly.
- The result: a bright, uniform panel of light without hot spots or dark areas.
