  • Display refresh
    Patent number: 7995068
    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.
    Type: Grant
    Filed: January 12, 2010
    Date of Patent: August 9, 2011

  • Sparse refresh of display
    Patent number: 7348987
    Abstract: A method, apparatus, and signal-bearing medium for sending to a display device modified regions of a frame buffer. A frame buffer is divided into the regions, and data in the frame buffer represents pixels on the display device. The frame buffer accumulates writes until the region being written to changes, at which time the region is copied to the display device.

  • Sparse refresh of display
    Patent number: 6995771
    Abstract: A method, apparatus, and signal-bearing medium for sending to a display device modified regions of a frame buffer. A frame buffer is divided into the regions, and data in the frame buffer represents pixels on the display device. The frame buffer accumulates writes until the region being written to changes, at which time the region is copied to the display device.
