A drive apparatus is provided which can calculate a suitable APL value when driving a color display panel using PLE control. Further, a drive apparatus is provided which can inhibit output capacity of a power supply circuit by controlling display brightness according to a lighting rate of a pixel. An APL calculation means 20 is provided with a weighting means 22 A for performing weighting according to a light emitting current rate of each color at the time of displaying a gray scale with respect to a picture signal of each of the colors R, G, and B. Being averaged by an averaging means 23 , each signal weighted by this weighting means 22 A acquires an APL value. The peak brightness control means 29 is controlled using this APL value so that PLE operation of controlling a peak brightness of the picture signal is realized. Further, a lighting rate calculation means for calculating the lighting rate of the pixel, in the display panel, which is lit and driven based on image data, and a brightness control means for controlling emission brightness of each of said pixels according to the lighting rate obtained by said lighting rate calculation means are provided.
