Abstract:
1. A display device for displaying display data, comprising: a display panel having pixel sections arranged in a matrix form; a scanning circuit which selects a line of the pixel sections; a gray-scale voltage generation circuit which generates a plurality of gray-scale voltages based on reference voltages; a selection circuit which selects a gray-scale voltage corresponding to the display data from the plurality of gray-scale voltages, and outputs a selected gray-scale voltage to a pixel section of the display panel; wherein current values of the gray-scale voltage generation circuit are changed according to a load of the display panel; and a conversion circuit which converts histogram data indicating frequencies for every one or more gray-scales of the display data into converted histogram data according to the load of the display panel; wherein the current values of the gray-scale voltage generation circuit are changed according to the converted histogram data.
