ABSTRACT:
In a display, capacitors are charged with first precharge voltages at the time of applying selection signals to previous scan lines. A data driver divides a plurality of data lines into a plurality of groups each of which consists of at least one data line and applies corresponding data voltages to the data lines of respective groups sequentially. The display further includes a precharge means, and such precharge means applies second precharge voltages to data lines of at least one group before selection signals for selecting scan line are applied to the scan line connected to the pixel circuits and stops application of the second precharge voltages before corresponding data voltages are applied to the respective groups. In this way, it is possible to solve the problem of poor images due to charge redistribution of the capacitors caused by previous data voltages stored in parasitic capacitors.
