ABSTRACT:
A display (8) comprises a display panel (9), a polariser (10), a polarisation rotator (13), and a scatterer (12) arranged to scatter light having a first polarisation as compared with light having a second polarisation. The display (8) can be switched between 2D and 3D modes by operating the polarisation rotator (13) accordingly. In 3D mode, the polarisation rotator (13) transmits light with relatively little or no change to its polarisation. Light transmitted by the scatterer (12) is then used to present a three-dimensional image (50). In 2D mode, the polarisation rotator (13) alters the polarisation of the light and light that is scattered by the scatterer (12) is used to present a two-dimensional image (51). The polarisation rotator (13) maybe arranged so that light incident on a first area thereof undergoes a different change in polarisation to light incident on a second area, in order to allow simultaneous presentation of 2D and 3D images (51, 50).
