Claim 16:
17. 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 determine that a first portion of image data in a current frame period is the same as a second portion of image data in a previous frame period, and that a third portion of the image data in the current frame period is different from a fourth portion of the image data in the previous frame period,
not to transfer the first portion of the image data to the data driver in a portion of an active period of the current frame period, and
to transfer the third portion of the image data to the data driver in another portion of the active period of the current frame, period,
wherein the controller transfers a clock training pattern to the data driver in the current frame period,
wherein the controller transfers frame configuration data to the data driver in a blank period of the previous frame period through a data transfer line, and
wherein the frame configuration data includes a shut down mode bit representing whether the data driver operates in a shut down mode.
