A virtual 3D display for a motor vehicle includes a substrate and a flexible display positioned on the substrate. The flexible display has two foldable sections and a main section. The main section provides a shared viewing area and each of the foldable sections provides a first and a second independent viewing area.

A system and method for simultaneously displaying, in plural spatially distinct zones via a multi-view display, differentiated content is disclosed. In accordance with the method, a plurality of spatially distinct zones are defined, differentiated content is assigned to the zones, a location for at least some of plural landing spots of beamlets projected by multi-view pixels of the multi-view display is estimated, the spatially distinct zone in which each said landing spots resides is determined, and beamlets associated with said some landing spots are driven to cause an appropriate content portion to be viewable at said some landing spots, as a function of location in a particular spatially distinct zone.

Disclosed is an imaging directional backlight including an array of light sources, and a control system arranged to provide variable distribution of luminous fluxes, scaled inversely by the width associated with the respective light sources in the lateral direction, across the array of light sources. The luminous intensity distribution of output optical windows may be controlled to provide desirable luminance distributions in the window plane of an autostereoscopic display, a directional display operating in wide angle 2D mode, privacy mode and low power consumption mode. Image quality may be improved and power consumption reduced.
