Abstract
Apparatus and method therefor reduces the ratio ft/Za for driving matrix displays where ft represents a signal processing clock frequency and Za represents the number of lines to be displayed on the matrix display. The time interval available for executing signal processing algorithms which drive a matrix display is expanded into time intervals in which a video signal contains no information. The invention is preferably used for driving LCD displays.
