Abstract: Determination means determines for every column pin whether or not display data of a current horizontal scan period (display time period) is the same as that of a next horizontal scan line (display time period). When the display data for one horizontal line are identical, an anode of an OEL element is connected to this terminal pin and then the drive current of the OEL element having a cathode to be scanned next in the vertical direction becomes substantially the same. Then, when a next vertical line is scanned for the column pin having display data, which is determined as identical, the resetting of the OEL element is inhibited by the reset inhibit circuit and the generation of peak current in a next horizontal scan period (display time period D) is stopped.
