METHOD AND APPARATUS FOR CONTROLLING A SELF-REFRESHING DISPLAY DEVICE COUPLED TO A GRAPHICS CONTROLLER |
摘要 |
A method and apparatus for controlling a self-refreshing display device coupled to a graphics controller are disclosed. A self-refreshing display device has a capability to drive the display based on video signals generated from a local frame buffer in the display device. A graphics controller coupled to the display device may optimally be placed in one or more power saving states when the display device is operating in a panel self-refresh mode. The graphics controller detects one or more progressive levels of idleness in the graphics controller and the pixel data stored in a frame buffer. Based on the detected idleness, the graphics controller signals the display device to enter or exit the panel self-refresh mode and enters a power saving state. When exiting the panel self-refresh mode, the display device and/or graphics controller ensure that the video signals generated by the local controller and the graphics controller are aligned.
