Abstract:
1. A driving device, for a display device, that displays a desired image on a display panel having a display element in which each of a plurality of pixels are arranged in a matrix form, comprising: a comparative calculation unit that compares, among pixel data corresponding to display content of each pixel in the matrix, by using pixel data corresponding to an nth horizontal scan line in an Nth frame and pixel data corresponding to an nth horizontal scan line of an (N−1)th frame; and a brightness determination unit that sets a brightness reduction ratio, the brightness determination unit determining the brightness reduction ratio with respect to pixel data corresponding to the nth horizontal scan line of the Nth frame or a later horizontal scan line of the Nth frame as a function of the comparative calculation and a total value of all pixel data from the nth horizontal scan line of the (N−1)th frame to an (n−1)th horizontal scan line of the Nth frame; and means coupled to the brightness control unit for controlling power supplied to the display element.
