Abstract: A driver integrated circuit (IC) chip includes gamma voltage generators, a line selector, and a data driver. The gamma voltage generators generate gamma voltage sets based on a reference voltage set. The line selector controls the connection between a plurality of voltage line sets for providing the reference voltage set and the gamma voltage generators based on a selection signal. The data driver converts input image data to data signals based on the gamma voltage sets.

Abstract: A display device includes a pixel, a data line, a scan line, a data driver, and a scan driver. The pixel is configured to display an image. The data line is configured to transmit data voltages to the pixel. The scan line is configured to transmit a scan signal to the pixel. The data driver is configured to: float the data line during a first period of a frame, apply, after the first period, a first data voltage to the data line during a second period of the frame, and apply, after the second period, a voltage waveform to the data line that varies the applied voltage from the first data voltage to a target voltage during a third period of the frame. The scan driver is configured to selectively apply the scan signal to the scan line.
