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 display panel includes a first display area on which a first gate line group is disposed and a second display area on which a second gate line group is disposed. The second gate line group is disconnected from the first gate line group. The timing controller is configured to determine a first driving frequency of the first display area based on first image data displayed on the first display area and a second driving frequency of the second display area based on second image data displayed on the second display area.
