Abstract
The invention provides an image display apparatus and an image display method of excellent image quality, by correcting the voltage drop resulting from the electrical resistance of the wirings with a simple configuration. There are provided adjustment data calculation means for calculating, for input image data, adjustment data for correcting the influence of the voltage drop resulting from the electrical resistance of the row wirings and gray scale number converting means for converting the number of gradation levels of the adjustment data. Modulation means outputs a signal modulated in the voltage amplitude to each column wiring, based on the adjustment data outputted by and subjected to the conversion of gradation levels by the gray scale number converting means.
