Method for driving a liquid crystal display device

Abstract

A video display for a liquid crystal display and a method for displaying a complex video signal thereon is provided. A line memory stores one line of video data of a complex video signal. A field memory stores one field of video data of the complex video signal. A signal driving circuit generates a signal driving signal in response to the video data stored in the line memory and the field memory. A multiplexer selectively transmits the video date from the line memory and field memory to the signal driving circuit. One horizontal period of the video signal is sequentially written in the line memory. During the first half of the horizontal period of the video signal, video data of the previous field which is stored in the field memory is transferred to the signal driving circuit. During the second half of the horizontal period, the video data stored in the line memory is transferred to the signal driving circuit. The signal driving circuit generates scanning driving signals for the liquid crystal display, each signal being divided into an odd and even field.
