Abstract: A display apparatus includes a mode determiner configured to compare image signals of a previous frame and a current frame and to determine an image mode of the current frame, a sync signal generator configured to generate a panel sync signal with a low frequency corresponding to the image mode using an original sync signal with a normal frequency, the low frequency being a non-divisor frequency of the normal frequency and lower than the normal frequency, a data driver configured to drive a data line of a display panel using a data sync signal based on the panel sync signal with the low frequency, and a gate driver configured to drive a gate line of the display panel using a gate sync signal based on the panel sync signal with the low frequency.

Abstract: A display apparatus includes a display panel and a timing controller. The timing controller generates first output image data based on input image data and sets a driving frequency of the display panel as a first frequency in a first operation mode. The timing controller converts the input image data into second output image data and sets the driving frequency of the display panel as a second frequency lower than the first frequency in a second operation mode. The display panel displays a first image based on the first frequency and the first output image data in the first operation mode. The first image is represented by X grayscales. The display panel displays a second image based on the second frequency and the second output image data in the second operation mode. The second image is represented by Y grayscales, where Y is less than X.

Abstract: A display apparatus includes a display panel, a first timing controller, a second timing controller and a third timing controller. The first timing controller controls an operation of a first region in the display panel, and generates a reference clock signal. The second timing controller controls an operation of a second region in the display panel, and receives the reference clock signal. The third timing controller controls an operation of a third region in the display panel, and receives the reference clock signal. The first, second and third timing controllers are synchronized with one another in response to the reference clock signal and a state synchronization signal, and operate in one of a plurality of states depending on an operation of the display apparatus.
