Abstract:
A display apparatus includes a display panel including a plurality of pixels, a data driver to provide data voltages to the plurality of pixels and to sense threshold voltages of the pixels, and a driving controller to generate first difference values by calculating differences between the data voltages for first pixels included in an N-th pixel row and the data voltages for second pixels included in an (N+1)-th pixel row among the plurality of pixels in an initial driving period, to calculate limit offset values for the second pixels based on the first difference values, to generate threshold voltage compensation values for the second pixels based on the threshold voltages of the second pixels, and to compensate input image data for the second pixels based on the threshold voltage compensation values and the limit offset values, where N is an integer greater than 0.
