ABSTRACT:
A display system includes a light source110and a spatial light modulator122located to receive light from the light source. The spatial light modulator (e.g., a DMD) includes a number of independently controllable elements that are activated for a period of time to display light of a desired brightness. A light sensor136is located to determine a characteristic of light from the light source110.A control circuit126is coupled to the spatial light modulator122and controls the period of time that the independently controllable elements are activated. This period of time is based at least in part by an input received from the light sensor136.
