Separating white light into polarized, colored light










Image Number 11 for United States Patent #6490017.

An electro-optic shutter is provided that includes first and second liquid crystal devices located along an optical path and first and second color-selective layers located between the first and second liquid crystal devices. Each liquid crystal device is adapted to rotate the polarization of incident light to a substantially orthogonal polarization in response to being in a first state, and to not substantially change the polarization of incident light in response to being in a second state. The first color-selective layer is adapted to transmit first and second colors and a first polarization of a third color. The second color-selective layer is adapted to transmit the first and the third colors and a second polarization of the second color that is substantially orthogonal to the first polarization. An electro-optic shutter is also provided that includes a color-selective layer, a liquid crystal device to receive light from the color-selective layer and a polarizer to receive light from the liquid crystal layer. The color-selective layer is adapted to transmit a first color, a first polarization of a second color, and a substantially orthogonal polarization of a third color. The liquid crystal device is adapted to rotate the polarization of light to a substantially orthogonal polarization when in a first state and to not substantially rotate the polarization of light when in a second state. The electro-optic shutter can be employed in projection systems.
