摘要： An exposure apparatus (8) for fabricating optical film (40) by exposing a pattern such as for photoalignment, where the optical film (40) has a photosensitive layer (20) and a substrate (10). The exposure apparatus (8) directs an exposure beam from a light source (1) to a reflective polarization modulation device (88). The modulated exposure beam is then directed onto the photosensitive layer (20) for forming a pattern onto the optical film (40). A reflective surface (50) is disposed to reflect, back through the optical film (40), a portion of the exposure beam transmitted through the optical film (40), in order to obtain a photoreactive response. The source of exposure radiation and the reflective surface (50) are on opposite sides of the optical film (40).

摘要： A transflective optical film reflects ambient light incident on the first surface and transmits light having a preferred polarization state incident on the opposite surface. The film has a substrate wherein a plurality of tapered cavities extends from a first surface of the substrate toward an opposite surface, the tapered cavities narrowing toward the opposite surface, and a filler material deposited within each the tapered cavity. A reflective layer is deposited on the filler material in each tapered cavity, along the first surface of the substrate. At least one of the substrate and the filler material is birefringent such that for a preferred polarization state, the refractive index of the filler is substantially lower than the refractive index of the substrate and that, for the polarization state orthogonal to the preferred polarization state, the refractive index of the filler is substantially the same as the refractive index of the substrate.

摘要： The invention relates to a method of forming a display comprising the steps of (a) providing a substrate; (b) forming a plurality of first conductors over the substrate; (c) depositing a layer of cholesteric liquid-crystal material, in the form of droplets of liquid crystal in a liquid carrier, over a preselected area of each of said first conductors so that a preselected portion of each of said first conductors is uncoated; (d) drying the liquid carrier to form a layer of polymer-dispersed cholesteric-liquid-crystal domains in a continuous matrix; and (e) forming a plurality of second conductors, electrically isolated from the first conductors, over the layer of polymer-dispersed liquid-crystal domains so that an electric field between the second conductors and the uncoated portions of the first conductors is capable of changing the optical state of the polymer-dispersed cholesteric liquid-crystal material. The absence of a coating over the second conductors permits connection to the first conductors without additional processing steps. The invention is also directed to a display element made by the method and to an array of display elements that represent an intermediate in the production of the final form of the display elements.

摘要： A display apparatus (10) including a light source (15) for forming a beam of light (130). A pre-polarizer (45) polarizes the beam of light (130) to provide a polarized beam of light. A wire grid polarization beamsplitter (50) receives the polarized beam of light and transmits the polarized beam of light which has a first polarization, and reflects the polarized beam of light which has a second polarization. A reflective spatial light modulator (55) selectively modulates the polarized beam of light that has a first polarization to encode image data thereon in order to form a modulated beam (360) and reflects the modulated beam back to the wire grid polarization beamsplitter (50). A compensator (260) is located between the wire grid polarization beamsplitter (50) and the reflective spatial light modulator (55) for conditioning oblique and skew rays of the modulated beam (360). The wire grid polarization beamsplitter (50) reflects the compensated modulated beam (360) and the wire gird polarization beamsplitter (50) is rotated in plane to optimize the contrast. A polarization analyzer (60) removes residual light of the opposite polarization state from the compensated modulated beam (360). Image-forming optics (20) form an image from the compensated modulated beam (360).
