摘要： A projection display includes a light source for generating a beam output that contains first, second and third color components, a color separation/synthesizing prism unit having a color separation part for separating the beam output from the light source into the first, second and third color components that exit the prism unit in three different directions, and first, second and third light modulators for modulating the first, second and third color components that exit from the color separation part. The prism unit further has a color synthesizing part that receives the modulated first, second and third color components from the light modulators and that synthesizes the modulated first, second and third color components so as to form an output beam. A projection lens receives the output beam from the color synthesizing part, and is used to project a color image. The first, second and third color components have equal optical path lengths measured from the light source to the respective light modulator. The first, second and third color components further have equal optical path lengths measured from the respective light-modulator to the projection lens.

摘要： 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.
