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.
