ABSTRACT:
A method for displaying a gray scale on a dot matrix type display device divides picture elements on a screen of the display device into partitions with N picture elements per partition. The picture elements correspond to (N+1) degrees of the gray scale display in which a binary level display signal is generated for representing a lighting and a lighting status. The method also upon setting each picture element to a desired degree of the gray scale display, provides that adjacent picture elements, at least in the same partition, have different phases with respect to the gray scale display. The picture elements arrayed at the same position in each partition have the same phase with respect to the gray scale display when their degree is the same.
