Abstract
A display device of a type for displaying in two levels is so controlled as to display images of different colors by hatching according to different patterns such that images of different colors can be distinguished. In order to prevent distortion of image caused by hatching, hatching corresponding to any particular color can be selectively prevented. With a binary conversion circuit with adjustable reference voltages, an image with various combinations of analog color signals can also be displayed.
