Abstract:
1. A method of driving a display device which comprises a plurality of pixels arranged in a matrix form and a driver circuit for driving the plurality of pixels, the method comprises the steps of: inputting n-bits digital signals to the driver circuit in a frame period for displaying a first gradation display wherein the n is a natural number; and inputting a first bit digital signal to an (m−1)th bit digital signal among n bits digital signals to the driver circuit in the frame period for displaying a second gradation display which has a lower gradation than the first gradation than the first gradation display without inputting an m-th bit digital signal to an n-th bit digital signal to the driver circuit wherein the m is a natural number equal to or greater than 2 and smaller than n, wherein the frame period has a plurality of sub frame periods and whether the pixel emits light or not is determined in each of the plurality of sub frame periods.
