1. An autostereoscopic display device comprising:
a display panel having an array of display pixels for producing a display, wherein the display pixels are arranged in rows and columns of different color sub-pixels; a lens array arranged in registration with the display panel for projecting a plurality of views towards a user in different directions, and comprising elongate lenses configurable to focus outputs of groups of the display pixels into the plurality of views projected towards a user in different directions, thereby enabling autostereoscopic imaging, wherein the elongate lenses have a long axis which is slanted at an angle θ to the general column pixel direction, wherein:s=±(α⁢⁢p2⁢c-(α⁢⁢p2⁢c)2-1) where s=tanθ, α is the aspect ratio of the pixels forming each of the plurality of views p is the pitch of the lenses across the pixel row direction, expressed as a number of sub-pixel widths, and c is the number of total sub-pixels forming each pixel of the display panel, wherein:0.8≤α≤10.8, and wherein:p=c⁢⁢Aα⁢⁢A-1 wherein A the reduction factor in resolution of the 3D view with respect to the resolution of the underlying panel.
