An assembly for producing a visual display includes a light-reflecting type spatial light modulator and an illumination arrangement for providing a particular source of light. The spatial light modulator has a light reflecting surface cooperating with a light modulating medium switchable between different states so as to act on light in ways which form an overall pattern of reflected, modulated light. The spatial light modulator also has an arrangement for switching the modulating medium between the different states in a controlled way so as to form the overall pattern. The overall assembly further includes an optics arrangement having a first member defining a light reflecting surface. The optics arrangement also has a second member defining (i) a first external face located in proximity to the illumination arrangement, (ii) a second external face located in proximity to the spatial light modulator, (iii) a third external face located in proximity to the light reflecting surface of the first member, and (iv) a fourth external face. The optics arrangement cooperates with the illumination arrangement and the spatial light modulator such that the spatial light modulator forms the overall pattern of modulated light from light provided by the particular source of light and such that the light reflecting surface of the first member forms a magnified image of the overall pattern which is viewable from within a predetermined area which extends away from the fourth face of the second member.

An assembly for producing a visual display said assembly comprising: (a) a light reflecting type spatial light modulator including a light reflecting surface cooperating with a light modulating medium switchable between different states so as to act on light in ways which form an overall pattern of reflected, modulated light, and means for switching said modulating medium between said different states in a controlled way so as to form said overall pattern; (b) illumination means for providing a particular source of light; and (c) optics means including a first member defining a light reflecting surface configured to direct reflected light into a predetermined area and a second member defining a first external face located in proximity to said illumination means, a second external face located in proximity to said spatial light modulator, a third external face located in proximity to the light reflecting surface of said first member, and a fourth external face, said optics means cooperating with said illumination means and said spatial light modulator such that said spatial light modulator forms said overall pattern of light from light provided by said particular source of light and such that the light reflecting surface of said first member directs light provided by the particular source of light from said spatial light modulator into said predetermined area extending outwardly from the fourth face of said second member in a way which allows a magnified image of the overall pattern of light formed at and by said spatial light modulator to be viewed from within said predetermined area, said overall pattern of light serving as said visual display.
