Abstract
A method of aligning a multiview backlight with a light valve array of a multiview display employs an alignment pattern that includes unit cells spaced apart from one another and having view blocks corresponding to different views of the multiview display. The method of aligning includes establishing the alignment pattern on the light valve array, illuminating the light valve array using the multiview backlight to display the alignment pattern, and adjusting a relative position of the multiview backlight and the light valve array to minimize an error measure of the unit cells within the displayed alignment pattern. A multiview display backlight alignment system includes the multiview display and a positioning stage configured to adjust the relative position to minimize the error measure. An automated multiview display backlight alignment system further includes a feedback controller, the positioning stage being motorized.
