Abstract
This invention relates to autostereoscopic display assemblies, in particular for hand-held devices such as tablets, i-Pads, mobile phones, etc., wherein a stereoscopic effect is achieved by forming light beams are emitted from the display at different angles and with different polarization. The display assembly comprises a sandwiched structure consisting of a light-guide panel and a modified liquid-crystal display that is applied onto the light-guide panel. The panel has on its outer surface a net of light waveguides for delivery of light from the light source and for uniform distribution of light over the entire surface of the display. The different polarizations and angular directions of the beams perceived differently by a viewer's left and right eyes are achieved by providing the light-distribution waveguides with holograms of two different types.
