Abstract
A display device which supports a panel self refresh (“PSR”) mode includes a source unit and a synchronizing unit, and a signal is transmitted between the source unit and the synchronizing unit through an interface. The source unit determines on/off of the PSR mode in response to a PSR setting value, and additionally determines whether to activate the PSR mode in response to luminance information.
Claims14
A display device which supports a panel self refresh mode, the display device comprising:
- a source unit;
- wherein
- the source unit activates the panel self refresh mode if a panel self refresh condition is met, and
- the panel self refresh condition includes whether a current image or image to be displayed has a luminance value equal to or greater than a predetermined reference luminance value.
A method of driving a display device which supports a panel self refresh mode and comprises a source unit, the method comprising:
- determining, by the source unit, whether a panel self refresh condition is satisfied;
- and
- based on determining that the panel self refresh condition is satisfied, activating, by the source unit, the panel self refresh mode,
- wherein determining whether the panel self refresh condition is satisfied includes determining, by the source unit, whether a current image or an image to be displayed has a luminance value equal to or greater than a predetermined reference luminance value.
