In a method for driving a display, one frame may be divided into more sub frames than a number of bits of data. A time period of the one frame may be divided into a number of periods corresponding to a number of scan lines multiplied by the number of sub frames. A start position of the sub frames may be set based on a bit weight of the data so that gradations are linearly expressed. Remainders of the sub frames may be obtained by dividing the start position of the sub frames by the number of sub frames. A line number of a scan line to which a scan signal is supplied may be obtained based on the time period of the one frame, the start position of the sub frames, and the number of the sub frames.
