  • Patent number: 9684338
    Abstract: A multifunctional device layer may include a lightguide substrate having an optically patterned surface and an opposing non-patterned surface. The non-patterned surface of the lightguide substrate is coated with a first material having a first refractive index and the patterned surface is coated with a second material having a second refractive index. The first refractive index may be lower than the second refractive index and each may be lower than a refractive index of the lightguide substrate. A touch sensor may be formed on the coated non-patterned surface of the lightguide substrate, the coated patterned surface, or on an interstitial layer deposited on the coated non-patterned surface or the coated patterned surface. An anti-glare/anti-reflective coating potentially having ultraviolet (UV) absorption properties may be applied to the touch sensor.

  • Patent number: 9256064
    Abstract: Subject matter disclosed herein relates to arrangements and techniques that provide for improving resolution of black and white images displayed by a display of an image display apparatus, for example an EWD. An electrowetting display device comprising a plurality of sub-pixels. Each sub-pixel comprises a substrate, an electrode layer on the substrate, and a hydrophobic layer on the electrode layer. A first fluid is disposed on the hydrophobic layer and a second fluid is disposed on the first fluid. The second fluid is immiscible with the first fluid. The plurality of sub-pixels is arranged in an angled relationship with respect to horizontal and vertical borders of the electrowetting display device.

  • Patent number: 4203124
    Abstract: Devices constructed according to the present invention provide low noise avalanche photodetectors. The devices are comprised of a sequence of at least four layers of semiconductor material of alternating opposed conductivity. In a first embodiment the layers form alternating homojunctions and heterojunctions at the interface between adjacent layers, and the bandgap of the layers on either side of the homojunctions decreases in the direction of the propagating signal. In another embodiment the layers form heterojunctions at the interfaces between adjacent layers; the layers are grouped into a sequence of pairs of layers where the bandgap of the two layers in each pair are substantially equal; and the bandgap of the layers in the sequence of pairs of layers decreases in the direction of the propagating signal. The effect of the structure of the multilayer device is to create traps for one sign of carrier and to prevent the trapped carrier from avalanching through amplification regions of the device.

  • Patent number: 4072544
    Abstract: Gallium arsenide antimonide phosphide (GaAsSbP) has been successfully grown on a gallium arsenide substrate by liquid phase epitaxy. A critical amount of phosphorus initially in growth solution is depleted with consequent grading of lattice constant and bandgap in the epitaxially grown layer. The substrate and graded layer as a subassembly are well suited for use in electronic devices such as double heterostructure lasers, light-emitting diodes, Schottky barrier diodes, and p-n junction photodiodes in the near-infrared low loss region of optical fibers.
