ABSTRACT:
A liquid crystal display is capable of displaying intermediate, partial or half tones of images, while at the same time preventing the occurrence of flicker and the decay of the liquid crystal panel. The display operation for data to be displayed in an intermediate tone has one or more lines of a repeating frame of display data that are prohibited from being displayed during in each frame. Such inhibited display lines are designated differently on a sequential basis over consecutive frames, and the sequence of designation is varied in successive frames in accord with changing patterns.
