Abstract:
1. A driving method of a flat panel display, comprising: converting a source data signal to a data signal, wherein the data signal has more bits than the source data signal, wherein the data signal is at least twelve bits; dividing one frame into a plurality of sub-frames corresponding to the twelve bits of the data signal, wherein each sub-frame includes an on-state time, each on-state time of each sub-frame corresponds to a weight value of each bit of the data signal expressed in a form of a binary code and a non-binary code, wherein the weight values are ratios of the on-state times to the on-state time which is a shortest time among the on-state times, the weight value of the shortest time is 1, and the other weight values are greater than 1; applying an on-state gate signal to a pixel in each sub-frame to turn on the pixel; and applying each bit of the data signal corresponding to each sub-frame to the pixel, wherein the weight values are expressed in a form of an increasing order such that a weight value of an (X+1)th sub-frame is always greater than a weight value of an Xth sub-frame for all positive integer values of X, and a weight value of a (Y+3)th sub-frame is always less than or equal to a summation of weight values of (Y+2)th and (Y+1)th sub-frames for all positive integer values of Y in the non-binary code part, wherein the sub-frames are in consecutive order of (Y+1)th, (Y+2)th and (Y+3)th, and wherein the weight values of first to third sub-frames of the plurality of sub-frames are expressed in the binary code, and the weight values of other sub-frames are expressed in the non-binary code.
