Abstract: A display apparatus includes a display panel, a gate driving part, a data driving part and a voltage providing part. The display panel displays an image, and includes gate lines and data lines. The gate driving part outputs gate signals to the gate lines. The data driving part outputs data signals to the data lines through data channels, and outputs a dummy data signal through a dummy data channel adjacent to a side of the display panel. The voltage providing part provides a driving voltage to the data driving part, receives the dummy data signal, and controls the driving voltage provided to the data driving part based on a voltage difference of the dummy data signal according to a time of the dummy data signal.

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.
