摘要： A lighting device for operation in at least two operating modes: a mode for free viewing and a mode for restricted viewing. The device includes a backlighting system, which in the restricted-viewing mode radiates light in a restricted angular range, a plate-shaped optical element situated along a viewing direction in front of the backlighting system, and illuminants laterally arranged at the optical element. The optical element is configured as a light guide consisting of a matrix plastic and, homogeneously distributed therein, scattering particles of a polymer. The light guide is transparent to at least 80% of the light emitted by the backlighting system. The light laterally incident on the optical element from the illuminants is radiated in a free viewing range; in the restricted-viewing mode, the backlighting system is switched on and the illuminants switched off; in the free-viewing mode, the illuminants are on and the backlighting system is off.

摘要： An apparatus is provided that includes a light source, a memory storing a visible light signal, a control circuit configured to control change in luminance of the light source in accordance with the visible light signal, and a receiver configured to receive another visible light signal, which rewrites over the visible light signal, by a communication method that is different from a visible light communication. The control circuit determines whether the visible light signal is rewritten by the another visible light signal or not when the receiver receives the another visible light signal, and the visible light signal is rewritten by the another visible light signal when the control circuit determines the visible light signal is rewritten by the another visible light signal. The control circuit controls the change in luminance of the light source to transmit the another visible light signal.

摘要： A two-dimensional/three-dimensional (2D/3D) switchable display backlight and a 2D/3D switchable electronic display employ a switchable diffuser to support 2D/3D switching. The 2D/3D switchable display backlight includes a plate light guide, a multibeam diffraction grating to couple light out of the plate light guide and the switchable diffuser to intercept and selectably either pass or scatter light beams of the coupled-out light. The 2D/3D switchable electronic display includes the backlight and further includes a light valve array to modulate the coupled-out light. The switchable diffuser facilitates selectability between a three-dimensional pixel and a two-dimensional pixel of the 2D/3D switchable electronic display.
