Abstract: A privacy display provides a private image exclusively visible within a viewing cone of a viewbox. The privacy display includes a light guide to guide light, a diffraction grating configured to diffractively couple out a portion of the guided light as diffractively coupled-out light and to direct the diffractively coupled-out light into the viewbox, and a light valve array configured to modulate the diffractively coupled-out light to provide the private image. An extent of the viewbox is determined by a collimation factor of the guided light. A dual-mode privacy display system further includes a broad-angle backlight configured to provide broad-angle light to separately provide a public image visible both inside and outside the viewing cone. The private image may be provided in a privacy mode and the public image may be provided in a public mode of the dual-mode privacy display system.
