Abstract: A mode-selectable backlight and privacy display employ directional scattering features to provide emitted light. The mode-selectable backlight includes a light guide, a first directional scattering feature to provide broad-angle emitted light from guided light having a first propagation direction within the light guide during a public mode, and a second directional scattering feature to provide second light from guided light having a second propagation direction within the light guide during a privacy mode. The directional emitted light the provided during the privacy mode is directed into a viewbox. The mode-selectable privacy display further includes light sources configured to provide the guided light having the first and second propagation directions along with an array of light valves configured to modulate the broad-angle emitted light as a public image and the directional emitted light as a private image visible within the viewbox.

Abstract: A grating-coupled light guide concentrates light and diffractively redirects the concentrated light at a non-zero propagation angle as guided light having a predetermined spread angle. The grating-coupled light guide includes a light guide, an optical concentrator, and a grating coupler. The optical concentrator is configured to concentrate light from a light source as concentrated light and the grating coupler is configured to diffractively redirect the concentrated light into the light guide as the guided light. Characteristics of the optical concentrator and grating coupler are configured in combination to determine the non-zero propagation angle and predetermined spread angle. A grating-coupled display system further includes an array of light valves configured to modulate emitted light as a displayed image.

Abstract: A polarized backlight employs a light source configured to provide polarized light and a light guide to guide the polarized light. A polarization-preserving scattering feature optically coupled to the light guide is configured to scatter a portion of the guided polarized light out of the light guide as emitted polarized light. A polarization of the emitted polarized light is determined by a polarization of the guided light.
