An apparatus (100) for use in driving a display, especially a color electrophoretic display comprising frame generating means generating a succession of frame pulses at regular intervals; frame blanking generating means generating a succession of frame blanking pulses at the same intervals; a plurality of input lines each arranged to receive one of a plurality of differing input voltages (Vin1, . . . VinN), all of the same polarity; an output line capable of being connected to a device driver (106); and switching means (102A, . . . 102N) connecting the output line to one of the input lines when no frame blanking pulse is present, the switching means (102A, . . . 102N) being capable of changing the input line to which the output line is connected during successive frame periods, the switching means (102A, . . . 102N) being arranged to drain charge from the output line when a frame blanking pulse is present. |

1. An apparatus for use in driving a display, the apparatus comprising:
frame generating means arranged to generate a succession of frame pulses at regular intervals; frame blanking generating means arranged to generate a succession of frame blanking pulses at the same intervals as the frame pulses; a plurality of input lines, each input line being arranged to receive one of a plurality of differing input voltages, all the input voltages being of the same polarity; an output line capable of being connected to a device driver; and switching means arranged to connect the output line to one of the input lines during the portion of each regular interval when a frame blanking pulse is not present, the switching means being capable of changing the input line to which the output line is connected during successive frame periods, the switching means being arranged to drain charge from the output line when a frame blanking pulse is present. |
