Abstract The gray level dependence of the color gamut on a LCD, PDP and CRT is evaluated in both dark and lighted rooms. The color gamut on the LCD decreases sharply with gray level, and the dark gray level color gamut on the LCD is smaller than that on the CRT or PDP in a dark room. However, in a lighted room, the gray level dependence of color gamut on the LCD is better than that on the PDP. A higher contrast ratio is effective for improving the color gamut on LCDs in the dark rooms and the value of over 10000:1 is a good guideline for LCD‐TV design.
