  • Patent number: 10126589
    Abstract: A virtual curved surface display panel, a method of manufacturing the same, and a display device are provided. A set of vertical lenticular lens and horizontal lenticular lens fitted tightly and orthogonally is arranged on a light exit surface of a pixel in the flat display panel, which forms an equivalent spherical lens. The focal lengths of the equivalent spherical lenses are symmetrically distributed with a central pixel as a symmetry axis, and focal lengths of the equivalent spherical lenses in the columns located on the same side of the symmetry axis are not equal to each other. Therefore, the equivalent spherical lenses enable the images of the pixels to form a curved surface, thereby realizing virtual curved surface display.

  • Patent number: 10108021
    Abstract: A system for stereoscopic visualization of image information includes a display device defining a display area for displaying a left and a right partial image. The display device displays the left partial image to a left eye of an observer focused on the display area in a first viewing direction using a left observation beam path and the right partial image to the right eye in a second viewing direction using a right observation beam path. The system includes a vision assist through which the left and right observation beam paths pass. The vision assist sets a beam course for the left and right viewing observation beam paths wherein, starting from the left and right eyes in a direction toward the display area, a perpendicular distance between the left and right observation beam paths decreases to a minimum at a finite distance from the display surface.

  • Patent number: 9995860
    Abstract: The disclosure is directed to a highly reflective multiband mirror that is reflective in the VIS-NIR-SWIR-MWIR-LWIR bands, the mirror being a complete thin film stack that consists of a plurality of layers on a selected substrate. In order from substrate to the final layer, the mirror consists of (a) substrate, (b) barrier layer, (c) first interface layer, (d) a reflective layer, (e) a second interface layer, (f) tuning layer(s) and (g) a protective layer. In some embodiments the tuning layer and the protective layer are combined into a single layer using a single coating material. The multiband mirror is more durable than existing mirrors on light weight metal substrates, for example 6061-Al, designed for similar applications. In each of the five layer types methods and materials are used to process each layer so as to achieve the desired layer characteristics, which aid to enhancing the durability performance of the stack.
