ABSTRACT:
A display comprises a backlight comprising a plurality of individually-controllable light emitters, a light modulator comprising a plurality of individually-controllable elements, and, a retro-reflective optical layer positioned between the backlight and the light modulator. The retro-reflective optical layer is configured to pass light incident thereon at an angle with respect to a normal to the retro-reflective optical layer of less than a threshold angle φ, and reflect light incident thereon at an angle with respect to a normal to the retro-reflective optical layer of greater than φ in a direction opposite and generally parallel to an incoming direction of incident light.
