Controller, hold-type display device, electronic apparatus, and signal adjusting method for hold-type display device

摘要

To provide a hold-type display device having a fine luminance efficiency while suppressing generation of motion blur. A controller according to the invention adjusts a signal outputted to a hold-type image display panel, which includes: a double-speed drive converting part which divides one frame of an inputted video signal to a plurality of sub-frames; a color converting part which converts a video signal of three primary colors including the plurality of sub-frames to a video signal of four or more colors including the three primary colors and a compound color; and a sub-frame converting part which converts, the video signal converted by the color converting part, to a signal having a plurality of different gradations whose average luminance value becomes equivalent to luminance of the video signal converted by the color converting part, and takes each of the plurality of gradations as each of gradations of the plurality of sub-frames.
