Abstract:
There is provided a driving circuit driving pixels each including an electro-optical device and a memory, in a display. The driving circuit includes: a dividing section dividing one frame period into subblocks composed of subfields, the subfields corresponding to respective bits of gray-scale data and having period lengths commensurate with weights of the corresponding bits; and an ON-OFF period control section controlling a ratio of an ON period or an OFF period to one frame period by bringing an electro-optical device of the pixel into an on state or an off state according to a corresponding bit in each of the subfields. On a subblock by subblock basis, the ON-OFF period control section selects scan lines whose number is less by one than a number of the subfields included in a relevant subblock, and again selects one of the selected scan lines during a same subblock period.
