Abstract
A display apparatus includes a display panel, a driving controller, and a data driver. The driving controller generates a data signal based on input image data. The data driver converts the data signal into a data voltage and outputs the data voltage to the display panel. The driving controller includes a deterioration compensator. The deterioration compensator generates an alpha value based on a ratio between a sensed current read from a portion of the display panel applied with a high power voltage or a portion of the display panel applied with a low power voltage and a predicted current calculated from the input image data and generates the data signal using the input image data, a stress value of a pixel, and the alpha value.
