Abstract
A self adjusting tiled image display system and method is provided. In operation, an image source having an array of tiled image displays projects a test image pattern. A positioning device is attached to a corresponding one of the image displays for positioning that image display. A sensor senses the test image pattern projected by the image displays and generates a sensor signal indicative of the sensed test image pattern. A processor compares the sensor signal to a proper alignment signal indicative of the image displays being properly aligned to generate a positioning signal. The processor applies the positioning signal to the positioning devices to position the image displays as a function of the positioning signal until the image displays are in the proper alignment.
