Classification: CPC G | IPC G

Claim 15:
16. A display device, comprising:
a display panel including a plurality of pixels;
a controller configured to output image data for the display panel; and
a data driver including a receiving block configured to receive the image data from the controller, and an analog block configured to provide data voltages to the plurality of pixels based on the image data;
a differential signal line including a first line and a second line located between the controller and the data driver, and configured to transfer the first and second image data;
a switch coupled between the first line and the second line; and
a termination resistor coupled in series with the switch between the first line and the second line,
wherein the controller detects a same data region of the display panel when the image data in a current frame period at least partially matches the image data in a previous frame period, does not transfer the 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 transfers the image data to the data driver in another portion of the active period of the current frame period,
wherein, in the same data period corresponding to the same data region within the current frame period, the receiving block or the analog block of the data driver is disabled,
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 receiving block of the data driver controls the switch to be turned off.
