    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.

    Abstract: A display device includes a controller to generate a start frame control signal having a first level in an active period and a second level in a blank period, a load signal toggling between the first level and the second level in the active period and having the second level in the blank period, and a data signal including image data in the active period and a training pattern in the blank period, and a data driver to recover the image data from the data signal based on an internal clock signal to provide display pixels with data voltages in the active period, and to perform a training operation for the internal clock signal using the training pattern in the data signal when both of the start frame control signal and the load signal are maintained as the second level for more than a reference time in the blank period.
