Classification: CPC G | IPC G

Claim 12:
13. A method of operating a display device, the method comprising:
generating load data of each of a plurality of panel blocks included in a display panel of the display device based on input image data;
generating life data of each of the panel blocks based on a deterioration stress value accumulated in the display panel;
generating operation data including a start time gain data indicating a start time set to a first time when the generated load data and the generated life data are greater than a threshold and otherwise set to a second time after the first time;
generating screen saver data based on the input image data and the operation data; and
maintaining a luminance of the display panel until the start time and then starting to adjust the luminance at the start time based on the screen saver data when operating in a screen saver mode for performing a screen saver operation mode,
wherein the luminance is maintained for a first period ending at the first time and the luminance begins being gradually decreased at the first time when the load data and the life data are greater than the threshold, and otherwise the luminance is maintained for a second period larger than the first period that ends at the second time and the luminance begins being gradually decreased at the second time.
