Abstract
A method, apparatus, and signal-bearing medium for sending to a display device only those regions of the display screen that change. A frame buffer is divided into tiles, which may be composed of one or more regions, and data in the frame buffer represents pixels on the display screen. When data representing a pixel is modified in the frame buffer, the region or tile associated with the pixel is marked as dirty, and those tiles or regions that are dirty in the frame buffer are written to the display.
