Abstract:
A display device having M data lines and N scanning lines arranged in a matrix and forming a plurality of display elements disposed at intersections of the M data and N scanning lines, wherein N and M are each integers greater than 1, for displaying an image, said display device comprising:a scanning line drive circuit for applying a scanning voltage signal possessing a specified selection voltage pattern simultaneously to n scanning lines from among the N scanning lines, wherein n is an integer greater than 1 and less than N;a buffer memory for accumulating display data representing the image to be displayed, said buffer memory comprising (n.times.M) buffer elements for accumulating at least (n.times.M) display data representing the image to be displayed;a frame memory for accumulating the display data from said buffer memory, wherein the (n.times.M) display data is written simultaneously in parallel into said frame memory, anda data line drive circuit for determining a data voltage signal to be applied to the M data lines in accordance with a comparison between the selection voltage pattern applied by said scanning line drive circuit and the (n.times.M) display data accumulated in said frame memory, and for applying the determined data voltage signal to the M data lines.
