Abstract(in Japanese) (See Japanese page)
Abstract(in English) We developed RGB-LED backlight system for LCD that has wide color gamut. When we use a plurality of colors of LED, we have some problems. The main problem is that changing brightness and white point that is cause by difference of light efficiency. So we need feedback control technique using a sensor for controlling LEDs. We developed single sensor feedback method and confirmed good effect due to minimize unevenness of a plurality of sensors. And we confirmed wide color gamut correspond to area of NTSC.
