A light-valve system adapted to recycle light reflected from the light-valve in order to improve the brightness of the image. Illustratively, this reflected light is the dark-state light of an image. The system includes a light-valve, which is optically coupled to a polarization discriminator; and a light recycling device, which selectively alters the polarization state of light reflected by the polarization discriminator back into the system, wherein the reflected light is transmitted to an imaging surface increasing the brightness of an image.
