  • Patent number: 10012884
    Abstract: A high-contrast electro-optic liquid crystal camera iris (10) provides angle independent transmission for uniform gray shades. The liquid crystal iris comprises a combination of first and second liquid crystal devices (12, 14) arranged in optical series and positioned between optical polarizers (46, 48). The director field (18) of the second liquid crystal device is a mirror image of the director field (16) of the first liquid crystal device, and the first and second liquid crystal devices are placed together so that the azimuthal directions (42) of the surface-contacting directors (18c, 22c) are in parallel alignment at the adjoining or confronting surfaces of the substrates (242, 321) of the first and second liquid crystal devices. The liquid crystal iris provides, therefore, less angular variation of intermediate transmittances compared with that provided by prior art liquid crystal irises.

  • Patent number: 9995954
    Abstract: A conductive film stuck to a transparent conductive film of a liquid crystal panel is protruded along a display surface and the protruded part is formed as non-adhesive so that the protruded part is not stuck to the members other than the liquid crystal panel. The protruded part contacts with a conductor on the front frame side so as to electrically connect the transparent conductive film of the liquid crystal panel and the front frame. When the liquid crystal panel moves, the conductive film can move in a direction in parallel to the display surface by following the liquid crystal panel, which prevents deterioration of the conductive film. Therefore, no excessive force works on the stuck part between the transparent conductive film and the conductive film. It solves the exfoliation issue of the conductive film, and the transparent conductive film can be electrically connected to the front frame stably.

  • Patent number: 9964820
    Abstract: A display may have a thin-film transistor layer and a color filter layer. The display may include light blocking structures formed on a transparent substrate. In one arrangement, a clear planarization layer may be formed over the light blocking structures. The thin-film transistor layer may be formed over the planarization layer. The color filter layer may be integrated with the thin-film transistor layer. At least light blocking structures and the planarization layer should be formed from high temperature resistance material. In another arrangement, the color filter layer may be formed on the light blocking structures. A clear planarization layer may then be formed over the color filter layer.
