  • Patent number: 10663830
    Abstract: Prior electrochromic devices frequently suffer from high levels of defectivity. The defects may be manifest as pin holes or spots where the electrochromic transition is impaired. This is unacceptable for many applications such as electrochromic architectural glass. Improved electrochromic devices with low defectivity can be fabricated by depositing certain layered components of the electrochromic device in a single integrated deposition system. While these layers are being deposited and/or treated on a substrate, for example a glass window, the substrate never leaves a controlled ambient environment, for example a low pressure controlled atmosphere having very low levels of particles. These layers may be deposited using physical vapor deposition. In certain embodiments, the device includes a counter electrode having an anodically coloring electrochromic material in combination with an additive.

  • Patent number: 10429553
    Abstract: An optical assembly includes a transparent substrate having a first major surface and a second major surface. The transparent substrate includes one or more damage layers disposed between a first non-damage layer and a second non-damage layer. Elongated laser-induced damage tracks are disposed within the damaged layer(s) to form at least one area pattern so that light directed toward the transparent substrate at an angle that exceeds a predetermined viewing angle (?) is scattered by the plurality of laser-induced damage tracks. Alternatively, if light is directed toward the transparent substrate at an angle that is less than the predetermined viewing angle (?), it is transmitted by the transparent substrate.

  • Patent number: 10416362
    Abstract: The high-brightness reflective luminous membrane of the present invention comprises (from top to bottom) a reflective layer and an attachment layer. The reflective layer is formed by a plurality of beads held in place by an adhesive. The attachment layer may adhere to a substrate. The beads may be transparent beads, which may reflect white light, or translucent beads, which are plated with metal via galvanization and may reflect colorful light. Either the attachment layer or the reflective layer may be provided with luminous powder, reflective powder, colors (or a first pattern) via coating, spraying, adhesion or printing to form a colorful reflective luminous layer. With the presence of incident light, the membrane can reflect high-brightness white light and/or bright colorful light. In addition, the membrane may exhibit various types of reflected patterns according to the distance to incident light source and brightness of incident light and a viewer's observing angle.

  • Patent number: 10416523
    Abstract: A electrophoretic display device manufacturing method includes bonding a substrate including a pixel electrode and a stacked film including a transparent electrode layer and an electrophoretic display layer, and forming a color filter layer having a pixel pattern corresponding to a pattern of the pixel electrode above a base material surface of the stacked film. The substrate has a region where the electrophoretic display layer is not arranged when the substrate and the stacked film are bonded, a pixel alignment pattern is drawn in the region, and in the forming the color filter layer, the color filter layer is formed while performing alignment using the pixel alignment pattern.

  • Patent number: 10394024
    Abstract: A display device is disclosed. The display device may include a display panel, a light blocking member, a distance sensing member, and a controlling member. The display panel may include a pixel region and a transmission region. The light blocking member may be disposed on a rear surface of the display panel and have an adjustable light transmittance. The distance sensing member may sense a viewing distance between a viewer and the display device. The controlling member may calculate a proper viewing distance range, may compare the viewing distance with the proper viewing distance range to generate a comparison result, and may adjust the light transmittance of the light blocking member based on the comparison result.

  • Patent number: 10394119
    Abstract: A system for the fabrication of patterned miniature structures, such integrated circuits, includes a continuous, flexible substrate that is transported by rollers to a series of processing stations. To ensure proper alignment amongst the various stations, the substrate is provided with at least one fiducial that is raised above its top surface a height that maximizes optical contrast when viewed interferometrically. At least one processing station includes an optical device that is capable of both interferometrically identifying the fiducial for alignment purposes and subsequently illuminating the substrate with a modifiable light pattern as part of a photolithographic process. Fiducials can also be used to identify gross geometric variances in the substrate caused by external factors, such as heat and moisture. In turn, a web adjustment element can be used to apply selective heat or tension to the substrate in order to correct such geometric variances.

  • Patent number: 10310298
    Abstract: A smart sensor-cover apparatus for covering a sensor, such as a vehicle sensor, includes controllable layers, responsive to inputs, such as a wavelength-filtering controllable layer to selectively filter out select wavelengths of light; a polarizing layer controllable layer to selectively polarize or allow through light; a concealing controllable layer to change between a visible state and a concealed state; and an outermost, cleaning, layer configured to melt incident ice. The outermost layer in various embodiments has an outer surface positioned generally flush with an outer vehicle surface for operation of the apparatus, to promote the concealing effect when the concealing layer is not activate. The outermost layer may be configured to self-mend when scratched, and in some cases is hydrophobic, hydrophilic, or super hydrophilic outer surface. An insulating component, such as a glass or polycarbonate layer, is positioned between each adjacent controllable layer.
