ABSTRACT:
A display driver which drives at least a plurality of scan lines of a liquid crystal device which has a plurality of data lines and a plurality of pixels in addition to the scan lines, the display driver including a plurality of scan drive cells; a plurality of scan order registers; and a plurality of coincidence detection circuits. Each of the scan drive cells drives one of the scan lines. Each of the scan order registers is connected to one of the coincidence detection circuits, and stores a scan order address which is used to show a scan order. Each of the coincidence detection circuits is connected to one of the scan drive cells, and outputs a result of comparison of the scan order address stored in each of the scan order registers with a scan line address designated by a scan control signal, to one of the scan drive cells.
