A driving circuit ( 25 ) for a liquid crystal display connecting to a host is provided. The driving circuit includes an image memory ( 251 ), a comparator ( 253 ), a counter ( 255 ) and an image converting means ( 259 ). The image memory stores a former frame's image data. The comparator compares a latter frame's image data provided by the host with the former frame's image data. The counter has a predetermined first threshold value and is configured to record an ongoing number of consecutive frames during which a latter frame's image data are the same as a former frame's image data. The converting means inverts a latter frame's image data into inverted frame image data when the ongoing number reaches the first threshold value.
