Abstract

Color reproductions for LCD (Liquid Crystal Display) panels are different from that of CRT (Cathode Ray Tube) display. Color reproductions for a typical color LCD panel for personal computer (TFT transmissive type for Sharp Mebius MN930-X23) are examined. The reproduction color gamut on the (x,y) chromaticity diagram are measured by varying the input digital levels. The color reproduction area becomes smaller in accordance with the lower input digital level. The correlated color temperatures also vary with the input digital levels. The lower the input digital levels, the higher the correlated color temperatures. The method for making the correlated color temperature constant is shown in this paper. The gamma curves for three primary colors are modified to fix the correlated color temperatures. The compensation of the correlated color temperature has been confirmed on the LCD panel.
