OUTPUT DRIVER OF ELECTRIC PAPER DISPLAY |
摘要 |
PURPOSE: An output driver of an electronic paper display device is provided to reduce peak current by distributively driving output drivers in a plurality of groups. CONSTITUTION: A plurality of positive drivers(121-171) receive positive voltages and are driven thereby. A plurality of negative drivers(123-173) receive negative voltages and are driven thereby. A plurality of switching units(122-172) is connected between the positive driver and the negative driver. The switching units connect or block the positive driver and the negative driver according to a control signal and output the data. The switching unit connects serially a plurality of transistors to each other or connects the transistors in parallel to each other.
