Abstract: Chemically-welded optical devices and associated methods for chemically welding optical devices are disclosed herein. Such optical devices may be used in display systems, and may include subcomponents comprising one or more optical films employed for polarization manipulation, as well as a substrate for protecting the optical film(s). An optical film may be chemically welded directly to the substrate using a solvent, and any additional optical films may be chemically welded to a prior optical film previously welded to the substrate. The chemical welding process of the present disclosure may include applying the solvent on the optical film in order to partially dissolve the surface of the optical film prior to adhesion to the substrate. Macromolecules on the dissolved surface of the optical film may be in a loosened state and may be realigned when the solvent evaporates.

Abstract: An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second deflected direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Viewing windows are formed through imaging individual light sources from the side of the waveguide and hence defines the relative positions of system elements and ray paths. A directional backlight with small footprint and low thickness may be provided.
