Patent ID: 7283181

Claim:
A display system comprising: at least one light source that directs light along an optical path; at least one filter wheel having a given optical filter characteristic; and a second filter wheel capable of at least one of rotating about a rotational axis distinct from a rotational axis of the first filter wheel or rotating independently of the first filter wheel; the display system being configured to produce a multi-color composite image formed of a plurality of differently colored component images, and to be selectively operable in a first state in which the entirety of the optical path does not pass through a first filter wheel and entirety of the optical path passes through the second filter wheel during production of the plurality of differently colored component images to form a multi-color composite image having a first optical characteristic, and in a second state in which the entirety of the optical path passes through the first filter wheel during production of the plurality of differently colored component images to form a multi-color composite image having a second optical characteristic different than the first optical characteristic.
