    Abstract: A display apparatus includes a display panel, a first driver and a second driver. The display panel includes a plurality of gate lines and a plurality of data lines. The display panel is configured to display an image based on input image data. The first driver is configured to output compensating gate signals having the same timing to the gate lines during a first period and scan gate signals having different timings to the gate lines during a second period. The second driver is configured to apply a compensating data voltage corresponding to a compensating grayscale value to the data lines during the first period and a target data voltage corresponding to a target grayscale value to the data lines during the second period.

    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 liquid crystal display having data driving apparatus comprising first and second output switches, a charge sharing line, and first and second charge sharing switches. The first output switch switches an electrical connection between a first amplifier providing a positive gradation voltage and a first data line in response to a control signal. The second output switch switches an electrical connection between a second amplifier providing a negative gradation voltage and a second data line in response to the control signal. The first charge sharing switch switches an electrical connection between the first data line and the charge sharing line in response to the control signal. The second charge sharing switch switches an electrical connection between the second data line and the charge sharing line in response to the control signal.
