Abstract
In situations with reduced image changes, display panels, such as the ones disclosed herein, may reduce their power consumption by performing self-refresh cycles, in which they may display locally stored data in the display panel instead of retrieving it from an image buffer. Methods and circuitry for management of the self-refresh cycle may reduce jitter, luminance errors, and/or flickers that may be caused by untimely self-refresh cycles that may occur as a result of latency in the image buffer. In some implementations, the display panel may have a dedicated low latency input that notifies an arrival of an incoming image. In some implementations, the self-refresh cycles of the panel may be managed by a host or a buffer that is responsible for sending the images.
