Abstract: A system for and method of projecting augmentation imagery in a head-mounted display is disclosed. A system for projecting light onto an eye includes a display to project light, a beam combiner, first and second optical systems between the display and the beam combiner along respective first and second optical paths. The first and second optical paths differ. The system also includes a switchable reflector that, in a reflective state, reflects light incident upon the reflector, and, in a non-reflective state, transmits light incident upon the reflector. The reflector is between the display and the first and second optical systems along the first and second optical paths and directs light along the first path, in the reflective state, or along the second path, in the non-reflective state, to reflect light from the beam combiner to the eye from different directions when in the different states.

Abstract: Provided is a display device which makes less flicker perceived in transition from a pause period to a drive period by suppressing image luminance from changing.Regardless of whether the number of pause frames in an immediately preceding pause period is high, or whether there is an image change immediately after a transition from the pause period to a drive period, high-speed scans are performed from Operating Frame One through Operating Frame Three, and BC drive is performed during Operating Frames One and Two. As a result, image luminance change immediately after the transition from the pause period to the drive period can be suppressed in a short period of time, and therefore, the occurrence of flicker as perceived by the viewer can be suppressed. Moreover, high-speed scans are performed only from Operating Frame One through Operating Frame Three, and therefore, power consumption in a liquid crystal display device 1 can be reduced.

Abstract: Disclosed herein are techniques related to privacy at display devices. The techniques include an apparatus having an electroactive privacy layer of a display device. The electroactive privacy layer is configured to restrict a propagation direction of light emission associated with a display layer of the display device. The restriction of propagation is generated by micro louvers formed in the electroactive privacy layer.
