    摘要： 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.

    摘要： A signal processing device includes a memory in which a color correction data is stored. The memory stores a first color correction data having the same number of bits as an input image data and a second color correction data having fewer number of bits than the input image data. The number of color correction data corresponding to a low gray-scale range increases and the number of color correction data corresponding to a high gray-scale range decreases by the same amount that the number of the color correction data corresponding to the low gray-scale range increased. Thus, a color characteristic corresponding to the low gray-scale range may be improved without changing the total number of color correction data.

    摘要： Provided are an image signal compensation apparatus and a liquid crystal display (LCD) including the same. The image signal compensation apparatus includes a lookup table (LUT) and an image signal compensation unit. The LUT includes reference data that corresponds to each combination of first and second reference gray levels and is arranged in a matrix. The image signal compensation unit receives first and second image signals, receives reference data corresponding to the first and second image signals from the LUT, and compensates the second image signal using the reference data. The reference data includes diagonal reference data located on a diagonal line in the matrix, and at least one diagonal reference data from among the diagonal reference data has a different value from a corresponding combination of the first and second reference gray levels.
