METHOD AND APPARATUS FOR PROVIDING INDICATION OF A STATIC FRAME

摘要

A method and apparatus provides for providing an indication of a static frame. In one example, the method and apparatus notifies the arrival of a static frame by changing a vertical blanking interval for the static frame. For example, the method and apparatus may determine that a display frame is a static frame if no graphic processing activity and/or lack of update to the frame buffer have been detected for a period of time. In response to a display frame being a static frame, the method and apparatus may change the vertical blanking interval that is immediately before the static frame by increasing the number of blanking scan lines in the vertical blanking interval. The changed vertical blanking interval may be transmitted with the static frame as an indicator of the arrival of a static frame, so that the apparatus may enter a self-refresh mode to repeatedly display the static frame.
