  • Patent number: 9176340
    Abstract: A fiber optic face plate for a display. The display includes a light source, a transparent cover, a diffuser, a brightness enhancement film, and the fiber optic face plate. The fiber optic face plate allows light to be transmitted through the fiber optic face plate based on the light being incident on the fiber optic face plate within an angular region defined by an acceptance cone. The fiber optic face plate absorbs light based on the light being incident on the fiber optic face plate outside the angular region defined by the acceptance cone. A top angular extent of the acceptance cone is positioned at a positive angle from a fiber optic face plate normal and a bottom angular extent of the acceptance cone is positioned at a negative angle from the fiber optic face plate normal.

    Abstract: A non-polarizing, Bragg-reflecting liquid crystal display is provided including a first and second substrate, liquid crystal material located between the first substrate and the second substrate. A fiber-optic faceplate may function as a first surface. Alternatively, a fiber-optic faceplate may be located on the side of the first substrate opposite from the liquid crystal layer. The fiber-optic faceplate may include optical fibers that extend between a front face and a rear face and fiber cladding materials located between the optical fibers. The fiber cladding material may be further opaquely masked on the front face.

  • Patent number: 6317189
    Abstract: A reflective display comprises a pair of substrates and a holographic polymer dispersed cholesteric liquid crystal (HPDCLC) material formed between the substrates. The holographic polymer dispersed cholesteric liquid crystal material comprises a holographic polymer dispersed liquid crystal material and a cholesteric liquid crystal material. These two materials reflect one or more different intrinsic colors such that individual cells of the display can reflect one or more different intrinsic colors. The cells can comprise more than two layers, with each layer being reflective of a different intrinsic color. The cells in such embodiments can reflect three different intrinsic peak wavelengths and one or more intrinsic colors, enabling the display to reflect all colors.

  • Patent number: 6166800
    Abstract: A full-color image capture system includes a color separation element and a single image sensor array. The color separation element can be operated in either a light reflective (mirror) mode in which selected intrinsic colors are reflected onto the image sensor array, or a light transmissive (filter) mode in which selected colors are transmitted to produce subtractive primary color images. The color separation element can be formed of holographic polymer dispersed liquid crystal materials that reflect light of selected intrinsic colors. The color separation element can include three holographic polymer dispersed liquid crystal material layers so that three different intrinsic colors can be selectively reflected or transmitted onto the image sensor to provide a full-color image.

  • Patent number: 5959711
    Abstract: A transmissive, backlit color twisted-nematic or super-twisted-nematic liquid crystal display employing a front fiber-optic faceplate or optical equivalent as a front retaining element of a liquid crystal cell that increases viewing angle between the display and a viewer while minimizing or eliminating undesirable variations in luminance, contrast ratio and chromaticity is described. In particular, the fiber-optic faceplate or optical equivalent includes cylindrical optical features and interstitial cladding material. The interstitial cladding material may include an opaque mask blocking layer to prevent the interstitial apertures from diffracting off-axis light into an observer's viewing cone. Further, the interstitial cladding material may be opaque.

  • Patent number: 5928819
    Abstract: Methods for making plates which have columnar features approximately in the direction of light propagation which are capable of total internal reflection, a controllable numeric aperture (NA) at input and output surfaces, rotational azimuthal averaging and translation of the object plane from a back surface of the plate to a front surface of the plate and are optical equivalent of a FOFP. These plates are made from a range of materials including a variety of monomer or polymer networks. The resultant plates contain adjacent areas with differing refractive indices which result in a substrate containing a plurality of cylindrical features whose boundaries are defined by a discontinuity of refractive indices wherein the index of refraction within the cylindrical features is greater than the index of refraction at the boundaries and external to the cylindrical features.

  • Patent number: 5703621
    Abstract: An array of light control units has an area large enough to present images for direct viewing. The array also has light control units sufficiently dense that ordinary acuity artifacts are not noticeable in presented images when the array is directly viewed at usual viewing distances by a human with normal vision. Signal circuitry can provide signals to the light control units. The array can present an image that includes M colors, where M is more than three, even though each light control unit can only cause presentation of one of a segment with one of a set of N colors, where N is less than M. Data defining an input image with M colors are used to obtain data defining an output image that is a version of the input image but includes, for each light control unit, a color data item indicating one of its set of N colors. The signal circuitry provides signals to the light control units so that each light control unit presents a segment with the color indicated by its color data item.

  • Patent number: 5491347
    Abstract: A thin-film structure on an insulating substrate includes an array of binary control units with an area of at least 90 cm.sup.2 and a density of at least 60 binary control units per cm. One implementation has an area of approximately 510 cm.sup.2, a diagonal of approximately 33 cm, and a total of approximately 6.3 million binary control units. Each binary control unit has a lead for receiving a unit drive signal, to which it responds by causing presentation of a segment of images presented by the array. Each binary control unit can present a segment with either a first color having a maximum intensity or a second color having a minimum intensity. Each binary control unit's unit drive signal causes the binary control unit to present its first and second colors. The substrate can be glass. Each binary control unit can include an amorphous silicon thin-film transistor (TFT) and a storage capacitor. Each binary control unit can be square.

  • Patent number: 5442467
    Abstract: A transmissive, backlit color twisted-nematic or super-twisted-nematic liquid crystal display employing a front fiber-optic faceplate as a front retaining element of a liquid crystal cell that increases viewing angle between the display and a viewer while minimizing or eliminating undesirable variations in luminance, contrast ratio and chromaticity is described. This novel configuration effectively decouples the liquid crystal cell and other optical elements behind the front fiber optic faceplate from the angular orientation of the viewer with respect to the display. The liquid crystal display described in this invention further provides a high quality color display, without viewing parallax, using a color selection filter mosaic outside of the liquid crystal cell.
