ABSTRACT:
A control circuit for use in a display device capable of displaying gray scale including a plurality of column electrodes and a plurality of row electrodes intersecting each other and pixels provided around the intersections thereof, includes a display data converting section for receiving input display data, dividing the input display data into binary display data and gray scale display data in such a manner as to enable pulse width modulation one frame in a plurality of frames, and outputting the binary display data and the gray scale display data: a pulse controlling section for determining the timing of applying a voltage to each of the plurality of column electrodes for the gray scale display data; and a column electrode driving section for applying a voltage corresponding to the gray scale display data to at least one said column electrode based on the timing of applying a voltage determined by the pulse controlling section.
