Abstract: Techniques for selectively updating regions of a display are disclosed. In the illustrative embodiment, a display engine of a computing device sends messages to a display to update particular update regions of the display. As not the entire frame is sent, sending only the update regions can save bandwidth and power. In the illustrative embodiment, some of the update regions for a frame sent to the display may be compressed and some of the update regions for the frame may be uncompressed. Due to overhead in the compression, sending small update regions uncompressed may reduce the bandwidth and/or power used.

Abstract: Techniques for selectively updating regions of a display are disclosed. In the illustrative embodiment, a display engine of a computing device sends messages to a display to update particular update regions of the display. As not the entire frame is sent, sending only the update regions can save bandwidth and power. In the illustrative embodiment, the display engine sends metadata to the display indicating when the last update message for a frame is sent. The display can then place the link between the display engine and the display in a low-power state to reduce power usage.

Abstract: In one embodiment, a system includes a display source to generate pixel data for a frame to be displayed, generate a display update notification message comprising information about the pixel data, and generate a display data message comprising the pixel data. The system also includes translation circuitry to generate one or more first packets comprising the information in the display update notification message and formatted according to an input/output (I/O) protocol based on the display update notification message, and generate one or more second packets comprising the pixel data and formatted according to the I/O protocol based on the display data message. The system further includes input/output circuitry to transmit the first and second data packets across a link based on the I/O protocol.
