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 controls operations of the gate driver and the data driver and drive a still image display area and a video image display area of a display area of the display panel in different driving frequencies. The driving controller includes a still image determiner which divides the input image data into a plurality of still image determining blocks, respectively determines whether the still image determining blocks represent a still image or a video image and determines a boundary between the still image display area and the video image display area.

Abstract: A display apparatus includes a display panel, a gate driver, a data driver and a driving controller. The display panel including a gate line and a data line displays an image based on input image data. The gate driver outputs a gate signal to the gate line. The data driver outputs a data voltage to the data line. The driving controller includes an area divider dividing the input image data into first and second area data, a first variable frequency driver determining a first driving frequency of the first area data based on a flicker value according to a grayscale value and generating a first data signal of the first driving frequency and a second variable frequency driver determining a second driving frequency of the second area data based on a flicker value according to a grayscale value and generating a second data signal of the second driving frequency.
