Abstract: A display apparatus includes a timing controller for converting data values of black image signals to have one polarity with respect to a common voltage and for converting data values of low gray scale image signals to have one polarity with respect to the common voltage, a data driver for converting the image signals outputted from the timing controller into data voltages, and a plurality of pixels for receiving the data voltages in response to gate signals to display an image. The low gray scale image signals displays a gray scale equal to or less than a reference gray scale at a surrounding temperature lower than a reference temperature.
