Abstract:
1. A display device, comprising: a display panel comprising a plurality of pixels, and scan lines and data lines electrically connected to the pixels; a timing controller for calculating statistic numbers of pixels whose gray-scale level variations between a previous frame and a current frame cross a gray-scale level of a gray point according to at least one scan-line-signal refresh time and at least one gray-scale lookup table, the timing controller to select a gray-scale lookup table from among plural gray-scale lookup tables corresponding to a lowest statistic number among the statistic numbers; and a data driver for generating pixel data according to the gray-scale lookup table corresponding to the lowest statistic number so as to output driving voltages of the pixel data to the pixels through the data lines; wherein the scan-line-signal refresh time is an interval time between pixels being successively turned on within a frame; wherein each statistic number is incremented when a gray-scale level of one of the pixels in an i
