Abstract: A display device may include a data driver that outputs a previous data voltage and a current data voltage, respectively, at an output terminal, to be applied to a pixel of a display panel in respective time intervals. A switch is controlled to open and close a circuit path between the output terminal and a data line coupled to the pixel. A capacitor stores an overdriving voltage. At least one further switch selectively applies the overdriving voltage to the data line from the capacitor when the circuit path is open and thereby enables a rapid transition of a voltage level of the data line between the previous and current data voltages, when the current and previous data voltages are to differ by more than a predetermined amount. As an example, the rapid transition between the previous and current data voltages may serve to minimize a color mixture phenomenon between pixels connected to a common data line and representing different colors.

Abstract: A pixel driver includes a plurality of stages, with each stage including a pixel driving signal generator, a shift register, and a selection circuit. The pixel driving signal generator generates a pixel driving signal. The shift register receives image data and the pixel driving signal and generates an output control signal for determining whether to output the pixel driving signal based on the image data and the pixel driving signal. The selection circuit selectively outputs the pixel driving signal in response to the output control signal.
