    摘要: 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.
