Claim 0:
1. A display device, comprising:
a display panel including a plurality of pixels;
a data driver configured to provide data voltages to the plurality of pixels; and
a controller configured to control the data driver, to detect a same data region of the display panel when first image data in a current frame period is at least partially the same as second image data in a previous frame period, not to transfer the first image data to the data driver in a same data period corresponding to a portion of an active period of the current frame period, and to transfer the first image data to the data driver in another portion of the active period of the current frame period,
wherein, before an end time point of the same data period, the controller transfers a clock training pattern to the data driver, and
wherein, in the same data period corresponding to the same data region within the current frame period, the data driver applies a shut down mode data voltage to a plurality of data lines of the display panel, and the shut down mode data voltage is not transferred to storage capacitors of the plurality of pixels in the same data region.
