Abstract:
1. A display control/drive device comprising: external terminals; a drive circuit which supplies from the external terminals on a time division basis, for each color in accordance with prescribed timing signals, voltages to be applied to a plurality of signal lines of a color display panel having a plurality of scanning lines and the signal lines arranged to cross the scanning lines; and a register for setting display modes, wherein, when a first value is set in the register, the outputs of the two, three or more groups are supplied at the same timing or, when a second value is set in the register, the outputs of the two, three or more groups are supplied at mutually different timings, and the sequence of outputs of the different groups is periodically varied, wherein a plurality of outputs for each color supplied from the drive circuit are divided into two, three or more groups, the output of each group is enabled to be supplied from a different timing from others, and wherein the sequence of outputs of the different groups is periodically varied when the outputs of those groups are to be supplied at mutually different timings.
