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 the display panel. The data driver outputs a data voltage to the display panel. The driving controller selectively determines a driving mode of the display apparatus between one of a normal driving mode and a low frequency driving mode, and determines a driving frequency of the display panel based on the input image data. The driving controller includes a flicker value storage storing flicker values for grayscale values of the input image data and a data remapper converting the grayscale value of the input image data to decrease a size of a maximum frequency grayscale area corresponding to a maximum driving frequency in the low frequency driving mode.
