Liquid crystal display
In a conventional liquid crystal display, for example, a grayscale display characteristic is changed by providing a plurality of grayscale voltage generation circuits which are selected by a selection circuit, which has resulted in a complicated circuit and consequently in a cost increase. A data conversion circuit 8 utilizing algorithm for performing arbitrary data conversion converts digital image data input from the outside and inputs the resultant data to driving circuits 3 through a control signal generation circuit 1. The source driving circuits 3 select one of a plurality of grayscale voltages generated by the grayscale voltage generation circuit 2 based on the converted digital image data and outputs the same to source lines, thereby changing the grayscale display characteristic.
