Abstract
A method and apparatus for performing display image refresh in bursts to a display device. A buffered refresh controller includes capabilities to drive the display based on video signals generated from a local frame buffer at a first rate. The graphics controller may optimally be configured to burst a new frame of pixel data to the buffered refresh controller at a second rate to replace the previous frame of pixel data in the local frame buffer. The second rate is different than the first rate. Additionally, the graphics controller may send frames only when they contain new pixel data. By enabling the graphics controller to selectively transmit the new frame of pixel data at the second rate, higher than the first rate, the graphics controller may be placed in a power-saving state during at least a portion of each frame update.
