Abstract:
1. An image display apparatus comprising: a plurality of image forming devices connected to a plurality of row wires and column wires respectively and arranged in a matrix pattern; scanning means connected to said row wires; modulating means connected to said column wires; gradation converting means for converting a gradation characteristic of input image data; corrected image data calculating means for calculating corrected image data, which is image data after correction for influence of a voltage drop caused by a resistance of said row wires and scanning means, for an output of the gradation converting means; and amplitude adjusting means having a function of multiplying data by a factor for adjustment of the amplitude of the corrected image data so that the amplitude of the corrected image data matches an input range of the modulating means, wherein said gradation converting means has a gradation conversion characteristic corresponding to said factor, and wherein said modulating means outputs modulation signals to said column wires, with entry of the corrected image data amplitude-adjusted by said amplitude adjusting means.
