Power Optimization with Dynamic Frame Rate Support

摘要

A frame of pixel data may be burst at a higher frame rate to create a lower effective refresh rate when the actual image update rate is lower than the frame rate. This results in the ability to power manage the transmit portion of the display engine and the receive portion of the panel electronics, while reducing display initiated repetitive memory traffic to conserve power.

主权项

1. A method comprising:
detecting an image that does not change for at least two frames; sending only the first frame of the image to a display panel over a display interface; causing a link shutdown for a period of the unchanging image; and power managing the display interface during the link shutdown.
