摘要:
The present invention can provide a driving apparatus capable of compensating an influence of a voltage drop at low costs in a simple manner, which includes: a column driver circuit that generates at least one of modulation signals different in start reference time in one horizontal scanning period and the modulation signals obtained by using pulse width modulation and voltage amplitude modulation in combination; and a correction circuit that corrects a voltage of the row selection signal so as to suppress a voltage variation of the row selection signal, which is caused due to at least a resistance of an output stage of the row driver circuit and a current caused to flow into the resistance.
