Abstract
A display device () configured to provide two-dimensional and three dimensional perception. The device comprises a display panel (), a backlight arrangement () and control circuitry (). The backlight arrangement comprises a first layer () in the form of an optically clear lightguide, a birefringent second layer () and a third layer (). At least one interfacing surface between any two of the layers comprises a microstructure () 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 () and second () 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.
