Abstract

This paper measures chromaticity parameters for Cold Cathode Fluorescent Lamp-Liquid Crystal Display (CCFL-LCD) and Light-Emitting Diode-Liquid Crystal Display (LED-LCD) display devices. The results show that using the LED as a backlight can improve effectively color restore ability of display device, the difference of the two color gamut coverage rates is 0.5 %, and the difference of three-dimensional color gamut volume is 0.15 × 105. The difference of intensity of the backlight source can change accordingly brightness of the white, red, green and blue, but it has no obvious impacts for color gamut of the displays. The result shows that in order to achieve wide color gamut, it is feasible to select a backlight, which has a better color reduction performance, a high luminous efficiency.
