Abstract
A circuit device includes a gradation voltage generation circuit, a correction processing circuit, and a driving circuit. The correction processing circuit performs correction processing on input display data to output corrected display data. The driving circuit drives an electro-optical panel by outputting gradation voltages corresponding to the corrected display data based on the gradation voltages. The gradation voltages are grouped into first to k-th groups. At this time, the correction processing circuit determines, by analyzing which group of the first to the k-th groups each input display data belongs to, a number of the input display data belonging to each group, and performs the correction processing based on the determined number.
