Abstract: A liquid crystal display comprises a backlight module comprising a reflective polarizing film, a light control film and a liquid crystal panel disposed between the backlight module and the light control film. The light control film comprises a light input surface and a light output surface opposite the light input surface and alternating transmissive and absorptive regions disposed between the light input surface and the light output surface. The absorptive regions have an aspect ratio of at least 30.

Abstract: The present disclosure describes advanced lighting elements, in particular solid-state lighting elements, and luminaires that include an array of lighting elements. The lighting elements, and luminaires including the lighting elements can exhibit benefits that include high optical efficiency and therefore high luminous efficacy; extraordinary directional control and therefore extraordinary glare control and efficacy of delivered lumens; and exceptional mixing of individual-device emission providing exceptional suppression of punch-through and color breakup. In many cases, the architecture can be amenable to low-cost manufacturing in a modular format.

Abstract: An optical stack including a periodically varying optical film layer and a grating assembly for reducing moiré is described. The grating assembly includes first and second layers where an interface between the first and second layers define a grating having a peak to valley height and an index contrast. The index contrast multiplied by the peak to valley height may be between 150 nm and 350 nm and the grating has a pitch in the range of 2 micrometers to 50 micrometers. Each of the first and second layers may be viscoelastic or elastomeric adhesive layers, crosslinked resin layers, or soluble resin layers.
