Abstract
A liquid crystal display has a liquid crystal panel having a plurality of data lines and a plurality of scanning lines arranged in a matrix form with pixels being formed at intersections of the data and scanning lines, a scanning circuit for successively applying a voltage to the scanning lines, and a liquid crystal driver for receiving display data from an external device to apply a voltage corresponding to the display data to the data lines. The scanning circuit includes a synchronizing signal generating circuit for generating a frame display synchronizing signal indicative of a frame period for display of image on the liquid crystal panel and a line display synchronizing signal indicative of a line period for image display on the liquid crystal panel. The liquid crystal driver includes a display memory accessed through a memory interface for reading and writing of data, the display memory storing therein display data corresponding to the pixels.
