ABSTRACT:
Provided is a fabrication alignment technique for a light guide screen. A plurality of light guide layers are provided. Each light guide layer includes a plurality of aligned light guides, each light guide having an input end, a midsection and an output end. The light guide layers are physically stacked. The input ends and the output ends are aligned. Vertical misalignment is detected with an optical detection device. In response to the detection of vertical misalignment, at least one light guide layer is horizontally adjusted.
