    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 device includes an oscillator which generates a reference clock signal having a frequency corresponding to frequency information provided from an external device, a register which stores a signal parameter for the reference clock signal, and the signal parameter indicates the number of pulses of the reference clock signal included in one horizontal time, a data driver which applies data signals to data lines connected to pixels based on the one horizontal time, and a controller which changes the signal parameter based on a change in the frequency of the reference clock signal in a way such that the one horizontal time is maintained substantially constant.

    Abstract: The display device includes a display panel, a printed circuit board on which a timing controller is mounted, and a connection film on which a data driver is mounted. Pixels and a gate driving circuit are disposed in a display area of the display panel. The connection film includes output lines connecting the data driver and the display panel, and first connection lines connecting the printed circuit board and the display panel. The first connection lines overlap the first area on which the data driver is mounted and are disposed between the output lines.
