Abstract
A method for generating data for driving a display panel is provided in which first compensation data of (N+k) bits, corresponding to grayscale data of N bits, is generated, wherein values of N and k are natural numbers. A first gamma curve is applied to the first compensation data of (N+k) bits. Second compensation data of (N+k) bits, corresponding to the grayscale data of N bits, is generated. A second gamma curve is applied to the second compensation data of (N+k) bits. The first compensation data or the second compensation data are selectively output and converted into analog data signals. The analog data signals are output to a data line. Accordingly, the first compensation data and second compensation data includes a multidomain structure which improves display quality. A data driving circuit and a display device including the data driving circuit for performing the method are also provided.
