Light module for LCD panel
View Patent ↗A light module is disclosed with an LED light for a LCD panel. LGP or LGS have mixed with well-mixed fluorescent powders therein and the white light with triple wavelength is made by the light rays emitted from UV LED to excite the well-mixed fluorescent powders. The present invention reduces the production cost and increases the color performance of the LCD.
