Abstract:
1. An image display apparatus having a plurality of pixels disposed at intersections between a plurality of row wirings and a plurality of column wirings, comprising: a row drive unit that is connected to the plurality of row wirings and sequentially outputs a scan signal to an addressed row wiring; a column drive unit that is connected to the plurality of column wirings and outputs modulation signals on the basis of luminance signals, to the plurality of column wirings in synchronism with the scan signal; and a control unit that generates the luminance signals on the basis of image signals and outputs the luminance signals to the column drive unit, wherein the control unit has a correction unit that performs a correction process on the image signals so as to suppress luminance fluctuation caused by capacitive coupling between adjacent column wirings, and the correction unit includes: a correction value generation unit that determines a correction value for a pixel to be corrected on the basis of a combination of a signal value of the pixel to be corrected and signal values of adjacent pixels which are on a column wiring next to a column wiring on which the pixel to be corrected is, and on the basis of a position of the pixel to be corrected in a column direction; and a correction operation unit that corrects a signal of the pixel to be corrected using the correction value generated by the correction value generation unit.
