Abstract:
1. A driving circuit for driving an electro-optical device having a pixel region in which a plurality of electro-optical elements is arranged in a matrix, comprising: correction data memory for storing block correction data corresponding to a plurality of blocks into which the pixel region is divided to correct control data that controls emission brightness of the electro-optical elements; a pixel correction data memory corresponding to each electro-optical element for storing data for correcting the emission brightness of each electro-optical element; the plurality of blocks comprising a plurality of block groups each being divided with different division schemes, each of the plurality of electro-optical elements belonging to more than two block groups, and the block correction data comprising a plurality types of data belonging to the plurality of block groups; a first correction circuit that provides correction data to the pixel correction data memory by using the plurality types of the block correction data obtained by the different division schemes; and a second correction circuit correcting the control data by using the correction data provided to the pixel correction data memory.
