    Abstract: This document describes techniques and apparatuses for implementing an object-detecting backlight unit for a display device. An object-detecting backlight unit includes two or more light sources configured to provide light to a display to form an image, and a light sensor configured to receive reflected light when an object is near the display and determine that the reflected light originated from a region of the display. The reflected light is caused by light from the image reflecting off of the object back towards the display. The backlight unit is configured to detect a position of the object based on the region of the display from which the reflected light originated.

    Abstract: A light guide device can provide a backlight for an LCD or a projection display. The light guide device includes a light-input end and an opposing end, opposing left and right sides which join the light-input end and the opposing end, and opposing front and back surfaces which join the light- input end and the opposing end. A birefringent film is provided on the opposing left and right sides of the light guide which switches a polarization of incident light. Incident light is provided at the light-input end having a right-handed circular polarization, in addition to light having a left-handed circular polarization. Light emitted from the front surface passes through a linear polarizer which selectively passes light to allow privacy of viewing by a user. The incident light can be provided at the light- input end using one or more cuboid rods, slab light guides, or discrete light sources.

    Abstract: Embodiments of optical collimators are disclosed. For example, one disclosed embodiment comprises an optical waveguide having a first end, a second end opposing the first end, a viewing surface extending at least partially between the first end and the second end, and a back surface opposing the viewing surface. The viewing surface comprises a first critical angle of internal reflection, and the back surface is configured to be reflective at the first critical angle of internal reflection. Further, an end reflector is disposed at the second end of the optical waveguide, and includes a faceted lens structure to cause a majority of the viewing surface to be uniformly illuminated when uniform light is injected into the first end and also to cause a majority of the injected light to exit the viewing surface.
