<p>An electronic (e.g., LCD) projector combines multiple projection lens assemblies with equal color component optical path lengths to provide improved display images and a compact arrangement. In one implementation, the projector includes a successive pair of angled dichroic mirrors that fold the red and blue color components of light in opposed directions. The green color component of light passes through the dichroic mirrors toward a pixelated electronic light modulator, such as a liquid crystal display, and an associated projection lens assembly. The red and blue color components of light are each folded again to propagate parallel with the green color component toward a pixelated electronic light modulator, such as a liquid crystal display, and an associated projection lens assembly. The separate projection lens assemblies are arranged in a non-linear, close-packed arrangement to receive the color components of light.</p> |
