摘要： A technique is described to reduce overfill of light that has exited a light integrating device and is applied to an optical modulator in the form of an illuminating pattern. The illumination reduction technique makes the illuminating pattern more closely conform to a active planar surface of the optical modulator by at least partially providing anamorphic magnification of the illuminating pattern.

摘要： A digital micromirror device arrangement and devices using the arrangement are disclosed. The arrangement includes a digital micromirror device (DMD) having an active area, a cover plate disposed substantially adjacent to the DMD and having a thickness and a light blocking area having an aperture formed therein. The active area is adapted to receive incoming light and to reflect the incoming light as outgoing light. The light-blocking layer is offset from a plane of the active area by at least the thickness of the cover plate and is adapted to block light from passing therethrough. The aperture is dimensioned to produce a beam of outgoing light having desired dimensions.

摘要： A display system is configured to produce a color image formed of a plurality of differently colored images and may include at least one light source that directs light along an optical path, and at least one filter having a given optical filter characteristic. The display system may be selectively operable in a first state in which the optical path does not pass through a first filter during production of the plurality of differently colored images to form a color image having a first optical characteristic, and in a second state in which the optical path passes through the first filter during production of the plurality of differently colored images to form a color image having a second optical characteristic different than the first optical characteristic.
