<p>The present invention relates to a gradation control method, for a display device, in which one frame is divided into a plurality of subframes (SF1' to SF5') and lighting times for pixels corresponding to the subframes are controlled based on the sum of respective light-emitting times in the subframes, so that gradations of the pixels are rendered; the frame is divided into n subframes (n = positive integer) (e.g., SF1' to SF4') in each of which m-bit data (m = positive integer) is set and a subframe (SF5') in which p-bit data (p = positive integer smaller than m) is set. As a result, increase in a data setting time can be suppressed, even if the number of subframes is increased in order to enable complicated gradation control.</p> |
