Abstract: 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.

Abstract: Some examples determine when to accumulate updates to a display device. In some implementations, a display manager may determine that a graphical user interface element, such as a user interface window, has opened or closed. The display manager may accumulate updates to a display device for a period of time or until a predetermined number of the updates have been received. After the period of time has elapsed or after the predetermined number of the updates have been received, the display manager may send a single update to the display device. The single update may include or may be equivalent to the one or more updates.

Abstract: Examples of when to perform a flash update to reset pixels of a display device are described. In some implementations, a counter may be modified in response to determining that one or more pixels of the display device have changed. An ambient temperature of the display device may be determined. A flash update of the display device may be performed based on the counter, the ambient temperature, or both.
