Abstract
A display apparatus includes a display panel, a gate driver, a data driver and a driving controller. The display panel displays an image based on input image data. The gate driver outputs a gate signal to a gate line of the display panel. The data driver outputs a data voltage to a data line of the display panel. The driving controller is configured to control an operation of the gate driver and an operation of the data driver, to determine a driving mode of the display apparatus among one of a normal driving mode and a low frequency driving mode, and to determine a driving frequency of the display panel based on the input image data. The driving controller includes a flicker value storage configured to store flicker values for a part of grayscale values among all of grayscale values of the input image data.
