Abstract
A static-image augmented privacy display, mode-switchable privacy display system, and method provide a private image to a first view zone and a static image to a second view zone. The static-image augmented privacy display includes a privacy backlight configured to provide directional emitted light to the first view zone and an array of light valves configured to modulate the directional emitted light to provide a private image within the first view zone. The static-image augmented privacy display also includes a static display layer configured to provide a static image in a second view zone. The mode-switchable privacy display includes a broad-angle backlight configured to provide broad-angle emitted light to both a first view zone and a second view zone during a shared mode, a shared image being provided by modulation of the broad-angle emitted light using the light valve array.
