Abstract
A display device is provided 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. A scanning line drive circuit applies a scanning voltage signal possessing a specified selection voltage pattern simultaneously to n scanning lines from among the N scanning lines, where n is an integer greater than 1 and less than N. First and second frame memory devices accumulate display data representing the image to be displayed, such that reading the display data of a first frame period from the first frame memory device is performed substantially simultaneously with the writing of the display data of a second frame period into the second memory device. A data line drive circuit determines a data voltage signal to be applied to the M data lines in accordance with a comparison between the selection voltage pattern applied by the scanning line drive circuit and the display data read from one of the first and second memory devices. The data line drive circuit also applies the determined data voltage signal to th…
