Abstract
Techniques for selective display frame fetching can include receiving or fetching rendered display frames by a display engine. The display engine can determine if a new frame includes one or more dirty portions. If the new frame includes one or more dirty portions, just the dirty portions can be loaded by the display engine into a display buffer. The display engine can also scan out just the dirty portions from the display buffer to a display.
