Abstract
A method for tiling multiple displays to generate a large area display of moving data. Specifically, one embodiment of the present invention includes a system for generating a large area display of moving data. The system comprises a display image generator for rendering pixels of an image to be displayed as the large area display. Furthermore, a plurality of tiled image projectors are coupled to the display image generator to receive pixel data and to generate the large area display. The plurality of tiled image projectors comprise at least two image projectors. A first image projector which performs a first type of raster scanning sequence to display a first portion of the pixel data. Moreover, a second image projector which performs a second type of raster scanning sequence to display a second portion of the pixel data, wherein the second type of raster scanning sequence is different than the first type of raster scanning sequence. Therefore, the present invention provides a method and system for tiling multiple image projectors to generate a large area display of moving images and data which is free of visual defects or anomalies. As such, the present invention is able to produ…
