Abstract:
1. A display system comprising: a light source for producing a beam of unpolarised light, a dynamic light modulator for dynamically modulating said beam of light with respect to polarisation, a first region of said modulator directing a first portion of the beam of light which has a first polarisation direction, said light with the first polarisation direction travelling along a first path, and rejecting a second portion of the beam of light not having the first polarisation direction, and a spatial light modulator on said first path for receiving light travelling along said first path and selectively modulating said light travelling along said first path to form an image light beam, wherein the dynamic light modulator is adapted as to, in operation, always illuminate only a part of the spatial light modulator on said first path, whereby the illuminated part scrolls over the spatial light modulator on said first path.
