Abstract:
A display device (200) configured to provide two-dimensional and three dimensional perception. The device comprises a display panel (230), a backlight arrangement (201) and control circuitry (232). The backlight arrangement comprises a first layer (210) in the form of an optically clear lightguide, a birefringent second layer (202) and a third layer (204). At least one interfacing surface between any two of the layers comprises a microstructure (206) in the form of a plurality of essentially parallel structures extending in a direction of extension (x) of the structures. The device further comprises first (218) and second (219) light sources that are configured to emit light into the lightguide in a first (z) and a second direction (-z), respectively. The first and second directions are essentially opposing directions and the first and second directions are essentially perpendicular to the direction of extension of the microstructure.
