Embodiment Construction
[0047] FIG. 2 depicts a display 8 comprising a display panel 9 in which a two-dimensional array of sub-pixels is defined; a polarizer 10 ; a lenticular screen 11 ; a polarization-dependent diffuser 12 and a switchable polarization rotator 13 . The display 8 also comprises a lighting system 14 configured to generate a backlight for the display panel 9 as described in detail below. In this particular example, each light ray causes a column of four sub-pixels in the display panel 9 to be illuminated. Each sub-pixel in this column can represent a different view, such as views A, B, C, and D, so that by aligning the appropriate pair of frames, a viewer in the appropriate position can perceive the 3D image.
[0048] In this particular embodiment, both the display panel 9 and the polarization rotator 13 comprise a layer of electro-optically active material, such as a liquid crystal material, sandwiched between two light transmissive substrates (not shown). In the case of liquid crys...
