First Claim
Patent Images
1. An electronic device, comprising:
- a processor operative to generate image data; and
a display communicatively coupled to the processor and operative to receive the image data from the processor and display an image based on the image data received from the processor, wherein the processor and the display are configured to operate in a streaming mode and a frame-buffered mode, and wherein the processor and the display are configured to switch alternatively between the streaming mode and the frame-buffered mode.

Abstract
Embodiments of the electronic device include a display driver with the ability to receive image data in a streaming display mode or a frame-buffered display mode. In some embodiments, the electronic device may switch seamlessly between the two display modes based on which display mode will provide reduced power usage given the type and/or variability of the image data being received.
