Abstract: A display device includes a timing controller, a data driver controlled by the timing controller, and a display panel configured to display an image by the data driver. When a data signal is applied in an abnormal state, the data driver generates a voltage for display of black by itself, and supplies the voltage to the display panel.

Abstract: A display apparatus includes where one pixel line including a plurality of pixels are provided in plurality, a gate driver configured to apply a gate signal to the one pixel line, and a source driver configured to apply a data signal to the one pixel line. The source driver includes amplifier circuits, output switches, a source output control circuit, and an offset control circuit. The source output control circuit applies sequentially delayed source output enable signals to the output switches to delay an output period of the data signal by units of source output channels, based on a degree of delay of the gate signal. The offset control circuit applies an offset control signal generated based on the sequentially delayed source output enable signals to the plurality of amplifier circuits to change an offset of each of the plurality of amplifier circuits in a masking period of the data signal.
