    Abstract: A display apparatus includes: a display panel which displays an image; a data driver which supplies a data voltage to the display panel in response to a polarity control signal, where the polarity control signal controls a polarity of the data voltage; a timing controller which outputs a polarity signal corresponding to a polarity of the data voltage; and a polarity converter which receives a common voltage from a common electrode of the display panel and the polarity signal from the timing controller, where the polarity converter outputs the polarity control signal to the data driver in response to a difference in voltage level between the common voltage from the common electrode and the polarity signal from the timing controller.
