Abstract: A display device may include: a plurality of pixels; a gate driver that receives clock signals and generates and applies a plurality of gate signals to a respective plurality of gate lines connected to the plurality of pixels; and a clock signal driver. The clock signal driver may output the clock signals and receive feedback clock signals derived from the clock signals, compare the feedback clock signals, and control amplitudes of the clock signals so that an amplitude difference between the feedback clock signals is less than a threshold.

Abstract: A display device includes a display panel including scan lines, first signal lines connected to the scan lines in a first pixel block, second signal lines connected to the scan lines in a second pixel block, third signal lines connected to the scan lines in a third pixel block; a first scan driver supplying a first output signal to the first signal lines based on a first sub-clock signal; a second scan driver supplying a second output signal to the second signal lines based on a second sub-clock signal; a third scan driver supplying a third output signal to the third signal lines based on and a third sub-clock signal; and a timing controller. Changes in pulse widths of the first to third output signals are different in one frame period.

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.
