ABSTRACT:
A display drive apparatus includes a selection circuit which sets display pixels in a plurality of specific rows of the display panel in a selected state with periods at least overlapping each other. A gradation signal generation circuit generates a gradation signal which controls a luminance gradation of each display pixel based on the display data and sequentially supplies the generated gradation signal in time series. A plurality of signal distribution circuits sequentially distribute the gradation signal supplied by the gradation signal generation circuit in accordance with the plurality of display pixels in each column at the timing of time-series supply. A plurality of current holding circuits individually hold the distributed gradation signal and simultaneously supply as the gradation current a current having a current value based on the held gradation signal to the display pixels in the plurality of specific rows.
