发明名称 Techniques to control self refresh display functionality
摘要 Techniques are described to monitor a level of graphics processing activity and control power usage based on the level. When no graphics processing activity is detected for a period of time, then a timing controller for a display device is instructed to capture a current image and repeatedly display the captured image. The graphics processing devices can be powered down. When graphics processing activity is detected, the graphics processing devices are powered up and the components used to capture an image and display the captured image are powered down.

主权项 1. An apparatus comprising: at least one processor to: cause transmission of frames for display;in response to a determination of a first level of graphics processing activity detected for a threshold period of time: request to enter self refresh display state, the request to enter self refresh display state to cause a frame buffer to capture an image once and display the captured frame multiple times andrequest reduction of power consumption of graphics processing components, wherein the graphics processing components comprise any of a phase lock loop, display plane, display pipe, or a display interface; andin response to a determination of a second level of graphics processing activity, cause activation of graphics processing components, cause transmission of a request to exit the self refresh display state, and cause disablement of the frame buffer.
