Abstract

Techniques are described that track the lines and pixels in a frame buffer in the host system that are being modified and transmit these modified scan lines and modified pixel locations to the self refresh display instead of entire contents of the frame buffer. The graphics adapter informs the self refresh display of the modified scan lines or pixel information and then sends the pixel data over the communications channel to the display. Custom codes can be used to identify and transmit modified scan lines and pixels to the self refresh display logic.
