Zusammenfassung: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.
