Abstract
A driving circuit for an image display device includes a signal generating circuit for generating an initiation control signal for controlling the initiation of sampling of a video signal to be input, and a sampling pulse timing signal for determining timing of sampling. When a set of discrete signals is input as the video signal, the signal generating circuit generates two sampling pulse timing signals whose phases differ from each other, selects one of the sampling pulse timing signals alternately in each horizontal scanning period, and outputs the selected sampling pulse timing signal to a shift register in a source driver. The signal generating circuit also switches the output signal between the two sampling pulse timing signals in a set of four fields.
