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: In a method of testing a display apparatus, a plurality of minimum compensation data for a plurality of grayscales, respectively and a plurality of maximum compensation data for the plurality of grayscales, respectively are determined. The display apparatus includes a display panel displaying an image having the plurality of grayscales. A plurality of grayscale compensation data corresponding to the plurality of grayscales, respectively are set based on the plurality of minimum compensation data and the plurality of maximum compensation data. A flicker characteristic with respect to the plurality of grayscales is measured based on the plurality of grayscale compensation data and test images displayed on the display panel. The flicker characteristic is optimized by selectively changing the plurality of grayscale compensation data based on the measured flicker characteristic.

Abstract: A method of driving a display panel includes determining a first black gap corresponding to a 2D mode and a second black gap corresponding to a 3D mode. The first and second black gaps are different from each other, the first and second black gaps correspond to a voltage difference between a black voltage of a first polarity and a black voltage of a second polarity, and the first and second polarities are opposite to each other with respect to a reference voltage. The method further includes dividing a voltage difference between a white voltage of the first polarity and the black voltage of the first polarity to generate a plurality of gamma voltages of the first polarity, and dividing a voltage difference between a white voltage of the second polarity and the black voltage of the second polarity to generate a plurality of gamma voltages of the second polarity.
