Abstract
A display system includes a light sourceand a spatial light modulatorlocated 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 sensoris located to determine a characteristic of light from the light source. A control circuitis coupled to the spatial light modulatorand 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 sensor
