A method of digitally driving an organic light-emitting diode (OLED) display is disclosed. In one aspect, the method includes calculating a first power consumption of a data driver for a first frame while first data bits are input to the data driver. The first data bits are input to the data driver in a data bit input order. The method also includes modifying the data bit input order and inputting second data bits to the data driver for a second frame in the modified data bit input order when the first power consumption is greater than a threshold power consumption.
