Abstract
An auto-stereoscopic display device includes a display panel having an array of display pixels for producing a display; and a view forming unit having an array of view forming elements. Each view forming elements is configurable to focus the outputs of groups of the display pixels into views projected towards a user in different directions. The display device further includes a view deflecting unit to selectably change the directions in which the plurality of views is projected towards the user. The view deflecting unit includes at least one birefringent prism having a first refractive index for light having a first polarization direction and a second refractive index for light having a second polarization direction. The view deflecting unit further includes a polarization switch in registration with the birefringent prism for providing the birefringent prism with display light having the first or second polarization direction.
