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.
Claims20
A display apparatus comprising:
- a display panel which displays an image, and comprises gate lines and data lines;
- a gate driver which outputs gate signals to the gate lines;
- a data driver which 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;
- and
- a voltage provider which provides a driving voltage to the data driver, receives the dummy data signal, and controls the driving voltage provided to the data driver based on a voltage difference of the dummy data signal according to a time of the dummy data signal.
A method of driving a display apparatus, the method comprising:
- increasing a data driving voltage applied to a data driver which outputs data signals to data lines, based on a voltage difference of a dummy data signal according to a time of the dummy data signal output through a dummy data channel adjacent to a side of a display panel displaying an image and comprising a gate line and the data lines;
- outputting a gate signal to the gate line;
- and
- outputting the data signals to the data lines using the increased driving voltage.
