Abstract
In an apparatus for driving a liquid crystal display panel having signal lines and scan lines, the operation of a signal line driving circuit for sequentially driving the signal lines is started by a horizontal start timing signal which is obtained by delaying a horizontal synchronization signal with a first time period. Also, the operation of a scan line driving circuit for sequentially driving the scan lines is started by a vertical start timing signal which is obtained by delaying a vertical synchronization signal with a second time period. The first time period and the second time period are changed in accordance with a size of one frame of a video signal.
