Abstract
A compact light valve projection system in which a high resolution monochrome or color active matrix light valve display is housed within a projector housing along with a light source, a projection lens and detachable speakers. The light source, light valve and projection optics are aligned along a single optical axis to provide a highly compact configuration.
Claims17
A light valve projector comprising:
- a housing for a light valve projector, a base section of the housing extending substantially perpendicular from the optical axis and having extendable support elements;
- an optical system contained within the housing and including a light source directing light along an optical axis, a lens positioned along the optical axis to receive light from light source and direct light onto a light valve, the light valve selectively transmitting light through a projection lens positioned along the optical axis to direct light onto an external viewing surface;
- a first audio transducer positioned on or within the housing and directing sound along a first direction;
- and
- a second audio transducer positioned on or within the housing and directing sound along a second direction.

A method for projecting images comprising:
- providing a housing for a light valve projector, a base section of the housing extending substantially perpendicular from the optical axis and having extendable support elements;
- providing an optical system contained within the housing and including a light source directing light along an optical axis, a lens positioned along the optical axis to receive light from light source and direct light onto a light valve, the light valve selectively transmitting light through a projection lens positioned along the optical axis to direct light onto an external viewing surface;
- providing a first audio transducer positioned on or within the housing and directing sound along a first direction and providing a second audio transducer positioned on or within the housing and directing sound along a second direction;
- and
- connecting a video source to the light valve to project images onto an external viewing surface.
