Two path liquid crystal light valve color display with light coupling lens array disposed along the red-green light path

A liquid crystal color display for displaying a full color image comprising

• light source means for providing a red light component and a green light component along a first optical path, and for providing a substantially collimated blue light component along a second optical path;
• first liquid crystal image forming means for receiving the red and green light from the light source means along the first optical path and for forming a red and green color image therefrom;
• the first liquid crystal image forming means having a plurality of individually addressable, light modulating display pixels;
• the plurality of light modulating display pixels having modulation means associated therewith for modulating the red and green light components according to the red and green image to be formed;
• light coupling lens array means disposed only along said first optical path for optically coupling the red and green light components received along the first optical path to respective ones of the plurality of light modulating display pixels;
• the light coupling lens array means having optical properties to collect the red and green light components and to focus a real image thereof in the respective ones of the plurality of light modulating display pixels;
• second liquid crystal image forming means for forming a blue color image;
• the second image forming means receiving the collimated blue light component from the light source means along the second optical path;
• image combination means for receiving the red and green color image and the blue color image from the respective first and second optical paths for combining by additive spatial superposition into a composite full color image;
• and
• image display means, disposed to receive the full color image from the image combination means, for displaying the composite full color image in a manner so as to be visible to a human observer.
