1. An autostereoscopic display device comprising:
a display having an array of display pixels for producing a display, wherein the display pixels are arranged in rows and columns of different colour sub-pixels; a lens array arranged in registration with the display 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=tan θ, 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 display sub-pixel widths, and c is the number of different colour sub-pixels forming each pixel of the display,
wherein:
0.8≦α≦1/0.8, and wherein:p=cAαA-1wherein A the reduction factor in resolution of the 3D view with respect to the resolution of the underlying panel.
