    Abstract: In a projection display, input light is separated by a polarization beam splitter prism into first and second color components, and a third color component. The first and second color components, together with a light leakage component that is associated with the third color component, are directed by the polarization beam splitter prism to a color synthesizing prism or a color splitter prism set, which then separates the first and second color components and the light leakage component so as to travel in three different directions, respectively. The first and second color components from the color synthesizing prism or the color splitter prism set, and the third color component from the polarization beam splitter prism are processed by reflective first, second and third light modulators, respectively.

    Abstract: A projection display is used to process a light beam that includes first, second and third color components and that is to be provided to a projection lens. The projection display includes a dichroic beam splitter which separates the first color component from the second and third color components. A first polarization beam splitter prism cooperates with a first reflective light valve to process the first color component. A second polarization beam splitter prism cooperates with second and third reflective light valves to process the second and third color components. A third polarization beam splitter prism is disposed so as to direct the processed color components from the first and second polarization beam splitter prisms to the projection lens.
