摘要： There is provided a driving circuit driving pixels in a display, the pixels each including a liquid crystal cell and a memory. The driving circuit includes: a dividing section dividing one frame period into subfields, the subfields corresponding to respective bits of gray-scale data and having period lengths commensurate with weights of the corresponding bits; a correction section correcting, when bit sequences of two sets of gray-scale data corresponding to two pixels adjacent to each other differ from each other, gray-scale data having a higher gray-scale level out of the two set of gray-scale data, to further increase the gray-scale level thereof; and an ON-OFF period control section controlling a ratio of an ON period or an OFF period to one frame period by bringing the liquid crystal cell of the pixel into an on state or an off state according to a corresponding bit in each of the subfields.
