    摘要： A signal processing apparatus and a signal processing method are disclosed. The signal processing apparatus includes a correction block and a division correction block. The correction block receives grayscale data comprising achromatic color grayscale data or chromatic color grayscale data to create corrected grayscale data. The division correction block receives the corrected grayscale data to create first division grayscale data and second division grayscale data having a grayscale value less than or equal to a grayscale value of the first division grayscale data. The correction block includes a first correction block and a second correction block. The first correction block receives the grayscale data and includes a one-dimensional lookup table to create corrected create achromatic color grayscale data. The second correction block includes a three-dimensional lookup table and an interpolator.

    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： A display substrate includes a pixel electrode and a photoalignment film. The pixel electrode is disposed on a base substrate. The pixel electrode includes a first sub-electrode, a second sub-electrode separated from the first sub-electrode, and a micro-slit pattern disposed on at least one of the first and second sub-electrodes. The photoalignment film is disposed on the pixel electrode to respectively divide the first and second sub-electrodes into a plurality of domains.
