ABSTRACT:
A display control device for a liquid crystal display is comprised of a detecting section for extracting a horizontal and vertical synchronizing signal from a video signal, a control signal generating circuit for generating a scanning start signal synchronous to the vertical synchronizing signal and a reference clock signal synchronous to the horizontal synchronizing signal, an X-driver circuit for extracting a horizontal picture signal from the video signal in synchronism with the horizontal synchronizing signal and supplying the horizontal picture signal to each of the horizontal pixel lines, and a Y-driver circuit having a shift register for shifting the scanning start pulse in one direction in response to the reference clock signal and selecting the horizontal pixel line corresponding to a holding position of the scanning start pulse, for supplying a selecting signal to the selected horizontal pixel line.
