Abstract
A display apparatus includes a display panel, a data driver, a driving controller and a power voltage generator. The display panel displays an image. The data driver outputs a data voltage to the display panel. The driving controller controls an operation of the data driver. The power voltage generator outputs a power voltage of the display panel. The data driver outputs a clock recovery signal representing whether a clock recovery operation is normal or abnormal to the driving controller. The driving controller generates an overcurrent signal representing an overcurrent based on the clock recovery signal and outputs the overcurrent signal to the power voltage generator.
