ABSTRACT:
A driver circuit for driving a display device includes N-number of grayscale selecting circuits, which correspond to N-number of data electrodes, each for selecting one grayscale voltage from among a plurality of grayscale voltages in accordance with an image signal; one voltage follower circuit for subjecting the grayscale voltages, which have been selected by the grayscale selecting circuits, to an impedance conversion to thereby drive the data electrodes; and a changeover control circuit for exercising control so as to divide one horizontal interval into at least (N+1)-number of intervals, drive a Kth data electrode by the output of the amplifier circuit by inputting only an output of a Kth grayscale selecting circuit to the amplifier circuit in a Kth (K=1 to N) interval, and drive the Kth data electrode by the output of the Kth grayscale selecting circuit in at least some intervals other than the Kth interval.
