    摘要: A driving apparatus of a liquid crystal display includes a signal modification unit which modifies a signal based on a data signal input to the liquid crystal display, where the signal modification unit determines whether the data signal corresponds to an image to be displayed with a quality deterioration and outputs at least one of a first signal and a second signal, where the first signal is output when the signal modification unit determines the data signal corresponds to the image to be displayed with the quality deterioration, and where the second signal is output when the signal modification unit determines the data signal does not corresponds to the image to be displayed with the quality deterioration.

    摘要: A liquid crystal display includes an image signal modifier for generating a modified signal based on a first image signal of a first frame, a second image signal of a second frame, and a lookup table. A data driver converts the modified signal into a data voltage which is supplied to a pixel of the display. The lookup table stores a plurality of reference modified signals for a plurality of reference first image signals and a plurality of reference second image signals. The lookup table includes a first lookup table having a gray gap of the reference first image signals and a gray gap of the reference second image signals of x, and a second lookup table having a gray gap of the reference first image signals and a gray gap of the reference second image signals of y, where y is greater than x.

    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.
