Color rendering is an important parameter to evalute the performance of a display. Uniformity of color rendering by digital driving methods of equal voltage change (EVC) and equal transmittance change (ETC) were studied. For each driving scheme, color differences of 4096 RGB digital combinations using CIELUV are caleulated. Histograms of the number of diseriminated colors v.s. hue angle are compared. More uniform color rendering of a LC module can be achieved by ETC driving.
