Progressive display updates

摘要

Techniques for performing progressive updates on displays of respective electronic devices. The techniques may update a display in two or more steps for the purpose of first providing a quick response and thereafter providing a higher quality rendering of the update. For instance, when the techniques receive an indication that the device has received an instruction to perform an update on a particular portion of the display, the techniques may compare one or more aspects of the update to one or more predefined criteria. If the update satisfies the criteria, then the techniques may instruct a display controller to first perform the update in black and white and may set a timer for later instructing the display controller to perform the update in grayscale.
