Optical film compression lenses, overlays and assemblies
Abstract:
A compression lens assembly is disclosed that includes one or more pieces of optical film with a top edge defining an X-axis, a bottom edge, a left edge defining a Y-axis, a right edge at a distance W from the left edge, and a Z-axis perpendicular to the X- and Y-axes. One or more parallel inward and or outward folds extend between the top and bottom edges. The compression lens assembly may include a lens containment feature with top and bottom channels configured to engagingly secure and restrict the corresponding top and bottom edges of the film in at least the Z-axis direction, and left and right channels spaced a distance smaller than W and configured to compress the left and right film edges together and restrict film movement in the X-axis direction. The compressed film piece may form one or more hill or valley profiles between adjacent folds.
