Patent ID: 7167314

Claim:
A projector comprising: at least first and second micro-displays; at least first and second cross total internal reflection (TIR) prisms respectively optically coupled to the at least first and second micro-displays, each of the at least first and second cross total internal reflection prisms having first and second total internal reflection interfaces; and a combiner optically coupled to the at least first and second cross total internal reflection prisms; wherein each of the at least first and second cross TIR prisms are respectively configured for receiving light at a first direction and configured to reflect the received light from the respective first TIR interface to the respective first and second micro-displays, and wherein each of the at least first and second micro-displays and at least first and second cross TIR prisms are configured to direct ON light through the respective first and second TIR interfaces to the combiner, and to direct OFF light from the respective second TIR interfaces at a second direction substantially the same as the first direction to a beam dump.
