Abstract:
1. A display signal generator for a display device including a pixel array unit of a plurality of aligned pixels and a plurality of light sources of different color components, configured to be able to adjust display brightness by modulating light from the light sources, and to reproduces a display color of an input image in each pixel by superposition of N number (where N is an integer of three or more) of sub-frame phases in the time direction, wherein in 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, and wherein when desired time aperture ratios in three continuous sub-frame phases among the three or more sub-frame phases are respectively represented as A the modulation signals satisfy the following inequality (2):
