This paper describes a novel driving scheme, ACC Accurate Color Capture, for improving color accuracy of LCD's. ACC changes RGB gamma curves separately to reduce the color shift with respect to the gray level. ACC dramatically reduced correlated color temperature shift from 3300K to 75K through 255‐64 gray range with 2.4 gray gamma value. As experimental results, ACC is little affected by gamma value variation of 2.0–2.8.
