Patent 7629945 was granted and assigned to Xerox on December, 2009 by the United States Patent and Trademark Office.
Two or more display units with different resolutions are combined such that the geometry of images displayed across the multiple display units is preserved and the image appears to be substantially continuous to a viewer of the image. Compatibility of the sizes of image elements on different display units is achieved by using display unit-specific scaling to compensate for the different pixel sizes on the individual display units.
