Abstract
A display has a light source, a spatial light modulator and an intermediate spatial light modulator. The display may be a front projection display or a rear-projection display. The spatial light modulator is illuminated with light from a light source. The intermediate spatial light modulator is located in a light path between the light source and the spatial light modulator. The light source may comprise an array of controllable light-emitters. The display may provide a high dynamic range.
