A display device includes a display panel including display pixels, and a display filter overlapping the display panel and including filter pixels that are greater in number than the display pixels, wherein in units of frame, each of the display pixels is configured to emit light at a luminance corresponding to one gray level, and wherein in units of sub-frames, each of the filter pixels is configured to be switched to a transmissive state or a non-transmissive state, wherein each of the sub-frames is shorter in period than a corresponding one of the frames.

Display device

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.

Display device and method of driving the same

A display device and a driving method thereof are provided. The display device includes: a display panel including a plurality of pixels; a timing controller for calculating an On-Pixel Ratio (OPR) of input image data with respect to an arbitrary frame, and correcting the input image data, based on the OPR; and a data driver for generating a data signal, based on the corrected image data, and providing the data signal to the display panel. The OPRs are calculated in units of pixel rows.
