Panel self refreshing with changing dynamic refresh rate

摘要

Provided are methods and systems for video data processing. In an exemplary system, there is a video source and a display unit. The display unit may receive video data from the video source and display it at a first refresh rate. The video source may cause the display unit to enter a power economy mode, in which the displayed video is static. In this mode, the video source stops sending new video data, while the display unit selectively stores one or more of the previously received video frames and further displays it repeatedly at a second refresh rate, which may be lower than the first refresh rate (e.g., it may be decreased from 60 Hz to 40 Hz). In the power economy mode, the power consumed is decreased, in some embodiments, by about 10-20 % for both the video source and the display unit.

主权项

1. A method for video data processing, the method comprising:
receiving video data from a video source, the video data comprising a sequence of video frames to be displayed at a first refresh rate; receiving, at a display, a first command from the video source to enter a power economy mode; selectively storing one or more video frames of the sequence of video frames in a buffer; and causing the display to repeatedly display the one or more video frames, wherein the one or more video frames are displayed at a second refresh rate lower than the first refresh rate.
