DISPLAY SIGNAL GENERATOR, DISPLAY DEVICE, AND METHOD OF IMAGE DISPLAY
First Claim
1. A display signal generator for a display device that has a pixel array unit of a plurality of aligned pixels and a plurality of light sources of different color components, that is configured to be able to adjust display brightness by modulating light from the light sources, and that reproduces a display color of an input image in each pixel by superposition of N number (where N is an integer of two or more) of sub-frame phases in the time direction, whereinin order to display an input image corresponding to an input image signal, a combination of desired time aperture ratios is obtained for each pixel in the N number of sub-frame phases, a combination of display time aperture ratios in the N number of sub-frame phases at the time the display color is actually reproduced is set from the combination of desired time aperture ratios on the basis of response characteristics of the pixel array unit, and a modulation signal for implementing the set combination of display time aperture ratios is output to the display unit.

Abstract
In a display signal generator for use in a display device, in order to display the image corresponding to the input image signals, a combination of desired display time aperture ratios are obtained for each pixel in N number of sub-frame phases, a combination of display time aperture ratios in the N number of sub-frame phases at the time the display color is actually reproduced is set from the combination of the desired time aperture ratios on the basis of response characteristics of a pixel array unit, and a modulation signal which implements the combination of display time aperture ratios that were set is output.
