Abstract
A method of operating a display device includes operating a timing controller in a normal mode. The timing controller generates a driving signal of a display panel in response to input data signal in the normal mode. The method includes operating the timing controller in a panel self-refresh mode. The timing controller generates the driving signal based on stop image data stored in a frame buffer in response to a first panel self-refresh start command in the panel self-refresh mode. The method includes inputting a second panel self-refresh start command to the timing controller during a synchronization procedure. The timing controller changes an operation mode from the panel self-refresh mode to the normal mode in response to a panel self-refresh end command in the synchronization procedure. The method includes controlling luminance of the display panel, by the timing controller, based on a length of a first vertical blank period.
