Multiview display alignment method and system

A multiview display backlight alignment system comprising:

• a multiview display having an array of light valves and a multiview backlight, the light valve array being configured to provide a displayed alignment pattern comprising a plurality of unit cells when illuminated by the multiview backlight;
• and
• a positioning stage configured to adjust a relative position of the light valve array and multiview backlight to minimize an error measure of the unit cells within the displayed alignment pattern,
• wherein unit cells of the unit cell plurality are spaced apart from one another, each unit cell comprising a plurality of view blocks having different view directions corresponding to different views of the multiview display and having an arrangement corresponding to an arrangement of the different views.

An automated multiview display backlight alignment system comprising:

• a multiview display having an array of light valves configured to provide a displayed alignment pattern when illuminated by a multiview backlight of the multiview display;
• a motorized positioning stage configured to adjust a relative position of the light valve array and multiview backlight;
• and
• a feedback controller configured to drive the motorized positioning stage to minimize an error measure of spaced-apart unit cells within the displayed alignment pattern,
• wherein the alignment pattern comprises a plurality of the spaced-apart unit cells, each of the spaced-apart unit cells comprising a plurality of view blocks having different view directions corresponding to different views of the multiview display and having an arrangement corresponding to an arrangement of the different views.
