Claim Text:
1. An apparatus comprising a plurality of stage circuits, each stage circuit including: a progressive driver to output a scan signal of a display device to an output terminal of the stage circuit, corresponding to a plurality of clock signals supplied simultaneously or progressively, wherein coupling between the progressive driver and the output terminal is blocked when a third control signal is supplied to the stage circuit; and a simultaneous driver to output a scan signal of the display device to the output terminal, corresponding to first and second control signals which do not overlap each other, wherein coupling between the simultaneous driver and the output terminal is blocked when a fourth control signal, which does not overlap the third control signal, is supplied to the stage circuit, wherein the first, second, third, and fourth control signals are display control signals for controlling the scan signals from the progressive and simultaneous drivers for generating images on the display device.
