Abstract

A BT.2020 wide color gamut is obtained using a laser backlight liquid crystal display (LCD). A conventional side-edge laser backlight requires a wide bezel area to achieve uniform brightness. We developed stacked double light guide plates, with each plate comprising light-mixing and light-emitting areas. The light-mixing area of each plate overlaps the light-emitting area of another light guide plate, thereby reducing the bezel width from 150 to 15 mm for a 17-inch LCD.
