Abstract
A display apparatus includes: a display panel configured to display an image based on input image data; a gate driver configured to output a gate signal to the display panel; a data driver configured to output a data voltage to the display panel; a driving controller configured to control an operation of the gate driver and an operation of the data driver, to determine a normal driving mode and a low frequency driving mode based on the input image data, and to determine a driving frequency of the display panel based on the input image data; and a touch driver configured to detect a touch event occurring on the display panel, and to output a touch interrupt signal representing the touch event to the driving controller.
