Abstract
The present invention is to provide an image display apparatus capable of properly correcting or adjusting, with small-scale hardware, variations in drive conditions due to electric resistance of matrix wiring on a display panel. The image display apparatus includes an adjusted image data calculation unit 14 for calculating adjusted image data as image data that has been compensated for the influence of voltage drop caused by resistance of at least the row wiring and a scan unit. The image display apparatus also includes an amplitude adjustment unit having a function for adjusting the amplitude of adjusted image data Dout, and a modulator 8 the takes in the adjusted image data with the amplitude adjusted and outputs a modulation signal to the column wiring.
