Abstract:
1. A display device for displaying display data, comprising: a display panel having pixel sections in a matrix form; a scanning circuit which selects a line of the pixel sections; a generation circuit which generates a plurality of gray-scale voltages based on a reference voltage; and a selection circuit which selects a gray-scale voltage corresponding to the display data from the plurality of gray-scale voltages, and outputs the gray-scale voltage thus selected to a pixel section of the display panel; wherein the generation circuit one of increases a steady-state current of the generation circuit at a charging and discharging period of the display panel, and decreases the steady-state current of the generation circuit at a stable period of the display panel within one scanning period of the scanning circuit, the steady-state current of the generation circuit being controlled based on a histogram of the display data so as to be increased or decreased by adding or subtracting offset data, having been set by a register, from the histogram of the display data within the one scanning period of the scanning circuit.
