Abstract: An image signal modifying method is disclosed. In one aspect, the image signal modifying method includes inputting a gray level interval of a first dynamic capacitance compensation (DCC) lookup table to a current gray level which is a target in a previous image signal when it is overdriven (DTG) and 0 to a gray level of the previous image signal (PIG). The method also includes searching for a data value in an adaptive color correction (ACC) lookup table corresponding to a gray level equal to a numerical value of the DTG (ALT) and performing an algorithm based on the DTG, the ALT, and the gray level interval of the first DCC lookup table. The method further includes generating a second DCC lookup table based on the algorithm, and performing second DCC processing on the input image signal based on the second DCC lookup table.

Abstract: A display panel driving apparatus is disclosed. In one aspect the apparatus includes a gate driving part and a data driving part. The gate driving part is configured to increase a gate signal applied to a gate line of a display panel from an OFF voltage to a ON voltage, in response to an activation of a gate clock signal. It is also configured to decrease the gate signal from the ON voltage to a kickback compensation voltage between the OFF voltage and the ON voltage through a plurality of steps in response to an activation of a kickback compensation signal. The data driving part is configured to apply a data signal to a data line of the display panel. Therefore, a data-charging rate may be increased, and thus a display quality of the display apparatus may be increased.

Abstract: A digital gamma correction part includes a memory and a selector. The memory is configured to store a basic gamma reference data, a first compensated gamma reference data and a second compensated gamma reference data, where respective data of the first compensated gamma reference data are greater than respective data of the basic gamma reference data, and respective data of the second compensated gamma reference data are less than respective data of the basic gamma reference data. The selector is configured to receive a luminance data determined based on a luminance of a display panel, and to output a gamma reference data by selecting one from the basic gamma reference data, the first compensated gamma reference data and the second compensated gamma reference data based on the luminance data and a gamma converted reference range.
