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 liquid crystal display system including a signal processing device uses interpolation to generate an intermediate image frame using previous image frame data and present image frame data. The system converts data of the intermediate image frame into transposed image data that is to be used to drive a liquid crystal display panel and display a corresponding image. The transposed image data and the present image data are subjected to a prespecified DCC process (dynamic capacitance compensation process) to thereby generate respective first and second compensation image data. Since the first compensation image data is generated based on the transposed image data and the transposition is configured to prevent over-compensation by the DCC process, over-compensation by the dynamic capacitance compensation process can be reduced or prevented.

A method for compensating data for a data compensating apparatus in a display apparatus includes converting image data of an n-th frame (where “n” is a natural number) into pre-compensation data of the n-th frame having a gray scale less than or equal to a gray scale of the image data of the n-th frame based on pre-compensation data of an (n−1)-th frame, storing the pre-compensation data of the n-th frame, and generating compensation data of the n-th frame having a gray scale greater than or equal to the gray scale of the image data of the n-th frame by using the image data of the n-th frame and the pre-compensation data of the (n−1)-th frame.
摘要:
A liquid crystal display includes a timing controller and a liquid crystal panel. The timing controller sequentially receives first through third primitive image signals and sequentially outputs first through third corrected image signals. The liquid crystal panel displays an image based on the first through third corrected image signals. The timing controller generates a first converted image signal having a first gray level based on the first primitive image signal and stores the first converted image signal. The second primitive image signal has a second gray level and the timing controller generates a second converted image signal having a third gray level higher than the second gray level when the second gray level is lower than the first gray level. The timing controller generates the third corrected image signal using the second converted image signal and the third primitive image signal.
