Abstract
The present invention is an automated testing apparatus and process for screen alignment involving a pattern generator, sensors, and an analysis computer. Two sets of patterns are displayed on the screen being tested. Sensors are used to observe patterns on the screen. An analysis computer receives the data from these observations and then compares the observed data to data from an ideal screen to determine the screen's alignment parameters.
