Abstract
This invention relates to an image display device that samples stabilized pixel data within a sampling period, to display an image with no ghosting. A liquid crystal panel 100 consists of pixels disposed at pixel positions formed at intersections between a plurality of data signal lines 112 and a plurality of scan signal lines 110 arranged in matrix form. A scan signal line selection circuit 102 supplies a scan signal to the scan signal lines 110 in sequence. The phase-expansion circuit 32 samples an image signal having time-series data corresponding to each of said pixel positions in accordance with a first sampling period, and outputs in parallel a plurality of phase-expaned signals that have been converted to a time length of data that is longer than the first sampling period. A plurality of sampling circuits 106 connected to corresponding data signal lines 112 each receive one of the plurality of phase-expaned signals, samples the pixel data in the phase-expaned signal according to a second sampling period, and supplies a data signal to the data signal lines 112. A sampling signal generation circuit 104 generates a sampling signal having the second sampling period that is short…
