ABSTRACT:
A display drive device which drives a display panel based on display data, the display panel including a plurality of scan lines and a plurality of signal lines, the signal lines being divided into a plurality of signal line groups, each of the signal line groups including a predetermined number of signal lines, a display signal generation circuit section which sequentially outputs display signal voltages based on the display data in a time sharing manner within each horizontal scanning period, and a selection circuit section which sequentially selects the signal line group corresponding to the display signal voltages output from the display signal generation circuit section in synchronization with an output timing of the display signal voltages, and applies the display signal voltages to the plurality of signal lines constituting the selected signal line group. The selection circuit section applies the display signal voltages to each signal line group plural times within each horizontal scanning period.
