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 includes a display panel, a gate driver, a data driver, and a driving control unit. The display panel includes pixels connected to a corresponding one of gate lines and a corresponding one of data lines. The gate driver drives the gate lines. The data driver includes first pads and second pads. The first pads are connected to each of first data lines of the data lines, and the second pads are connected to each of second data lines of the data lines. The driving control unit provides control signals and a data signal to the data driver, and to control the gate driver. The data driver includes a digital-to-analog converter and a switching circuit. The digital-to-analog converter converts the data signal into analog signals. The switching circuit sequentially outputs the analog signals to the first pads during a test mode.
