    摘要： A multipurpose liquid crystal display, suitable for use as a reflective display and as overhead projection panel, includes (a) a first transparent electrode means; (b) a second transparent electrode means; (c) a display medium positioned between the first and second transparent electrode means, which display medium is switchable between a first state in which incident light is scattered and a second state in which the amount of such scattering is reduced; (d) a retroreflector removably positioned behind the second transparent electrode means; and (e) means for removably positioning the retroreflector behind the second transparent electrode. Preferably, the display medium comprises positive dielectric anisotropy, operationally nematic liquid crystals dispersed in a containment medium.

    摘要： A system and method for projecting a color image is disclosed. The system includes a light dispersing system arranged in the path of a composite light beam for separating the composite light beam into spatially separated component beams, an image display arranged in the path of the component beams for producing modulated component beams, and a beam merging system producing a second light beam by merging the modulated component beams. The method includes producing spatially separated component light beams, directing the spatially separated component light beams to the surface of an image display, modulating display cells of the image display, and producing modulated component light beams.

    摘要： An optical projection system has a display cell that is configured to project a display image in response to light striking the display cell. The system has a light source that is configured to project a beam of light and a lens array that is positioned to intercept the beam and generate multiple beamlets of the beam. An aperture assembly is positioned to intercept the beamlets and is configured to selectively control which portions of the images contained in the beamlets strike the display cell.

    摘要： A display having a first electrode means; a second electrode means; and a display medium positioned between the first and second electrode means, which display medium contains a pleochroic dye, is switchable between a first state in which incident light is substantially absorbed by the pleochroic dye and a second state in which the amount of such absorption is substantially reduced, and is capable of scattering incident light with a scattering half angle between about 5 and about 40 degrees when the display medium is in its second state, while permitting at least 10% of the incident light to be transmitted. The absolute difference between the ordinary index of refraction of the liquid crystal and the refractive index of the containment medium is 0.10 to 0.20.
