Display panel having self-refresh capability

A display device, comprising:

• a display panel having a plurality of pixels;
• an application processor arranged to receive a video stream;
• and
• a source circuit connected to the display panel so as to be arranged to drive the pixels according to image data values corresponding to the video stream;
• wherein the application processor is programmed to compare corresponding portions of successive frames of the video stream to determine whether the corresponding portions are substantially identical, and wherein the source circuit is programmed to refresh voltages of the pixels corresponding to the substantially identical corresponding portions instead of driving the image data values thereto.

A method of refreshing an image generated by a display, the method comprising:

• receiving a video stream corresponding to images to be displayed;
• comparing corresponding portions of successive frames of the video stream to determine whether the corresponding portions are substantially identical;
• refreshing voltages of pixels of the display that correspond to the substantially identical corresponding portions of the successive frames;
• and
• driving image data values to pixels of the display that do not correspond to the substantially identical corresponding portions of the successive frames.
