  • Patent number: 6588949
    Abstract: A hermetically sealed photonic device submount includes a photonic device mounted on a substrate material and sealed in a flexible hermetic seal. In one configuration, the photonic device is configured to emit or to receive light through the substrate material. In this configuration, the photonic device is covered with an adhesive layer and a metal layer deposited onto the adhesive layer. In another configuration, the photonic device is configured to emit or to receive light in a direction substantially vertically upward from the substrate material. In this configuration, a cover is placed over the photonic device, then the cover is hermetically sealed to the substrate material with an adhesive layer and a metal layer depositd onto the adhesive layer. In both configurations, the photonic device submounts are hermetically sealed according to various aspects of the present invention on the substrate material without using a separate package.

  • Patent number: 5717474
    Abstract: A multi-domain halftone gray scale active matrix liquid crystal display utilizing a mono-gap configuration for achieving a very wide viewing angle at a low-cost. The substrate of the display has areas having a rub or an alignment of different directions from the direction of the rub or alignment in other adjacent areas. Each pixel of the gray scale matrix has a plurality of subpixels such that each subpixel turns on at a different voltage than that of the other subpixels. The areas involving different rubs or alignments on the substrates may be areas of pixels or subpixels. At least one compensating retardation layer is formed on the display. The technique of enabling the combining of multiple domains and compensation with halftone grayscale pixels results in a display having significantly wider viewing angles than either a multi-domain display or a halftone grayscale display, whether compensated for or not.
