Abstract: A nanoimprint lithography mold, nanoimprint lithography tiling system, and method of dicing a nanoimprint lithography substrate employ a nanoimprint lithography mold having a precision edge and an undercut sidewall. The precision edge has nanoscale roughness and is adjacent to a top surface of the nanoimprint lithography mold at a predetermined distance from a feature of the nanoimprint lithography mold. The undercut sidewall extends from the precision edge to a bottom surface of the nanoimprint lithography mold. The undercut sidewall has a surface that is angled away from the precision edge and toward a center of the nanoimprint lithography mold. The precision edge and the undercut sidewall define a side of the nanoimprint lithography mold that can be abutted with corresponding sides of one or more other nanoimprint lithography molds.

Abstract: A directional backlight is disclosed. The directional backlight has a plurality of light sources to generate a plurality of input planar lightbeams. The plurality of input planar lightbeams illuminates a directional backplane that has a plurality of directional pixels to scatter the plurality of input planar lightbeams into a plurality of directional lightbeams. Each directional lightbeam has a direction and angular spread controlled by characteristics of a directional pixel in the plurality of directional pixels. The directional backlight can be used to generate a 3D image by specifying the characteristics of the directional pixels in the directional backplane.
