  • Patent number: 9368517
    Abstract: A light-emitting device having the quality of an image high in homogeneity is provided. A printed wiring board (second substrate) (107) is provided facing a substrate (first substrate) (101) that has a luminous element (102) formed thereon. A PWB side wiring (second group of wirings) (110) on the printed wiring board (107) is electrically connected to element side wirings (first group of wirings) (103, 104) by anisotropic conductive films (105a, 105b). At this point, because a low resistant copper foil is used to form the PWB side wiring (110), a voltage drop of the element side wirings (103, 104) and a delay of a signal can be reduced. Accordingly, the homogeneity of the quality of an image is improved, and the operating speed of a driver circuit portion is enhanced.

  • Patent number: 9231378
    Abstract: A spark plug for an internal combustion engine includes a center electrode, a tubular insulator, a tubular metal shell, a ground electrode and an overvoltage preventer. The insulator has the center electrode inserted and held therein. The metal shell has the insulator inserted and held therein such that a proximal part of the insulator is exposed from the metal shell. The ground electrode is joined to a distal end of the metal shell and faces the center electrode through a spark gap formed between the center and ground electrodes. The overvoltage preventer prevents a voltage higher than or equal to a threshold voltage from being applied across the spark gap. The overvoltage preventer is arranged in the proximal part of the insulator so as to be positioned outside the metal shell and farther than the metal shell from the spark gap.

  • Patent number: 9190456
    Abstract: An arrangement for a high resolution active matrix display includes organic emissive layers of distinct colors each deposited across continuous regions so as to include more than one pixel emissive region. Color filters are situated to partially block light from at least some of the emissive regions such that primary additive colors are transmitted from distinct subsets of pixels. The emissive layers may be deposited in alternating parallel stripes along rows or columns of the display, or may be oriented perpendicularly with respect to one another such that the emissive layers overlap in the emissive regions of at least some pixels. In some examples, red, green, and blue of pixels are arranged in regular patterns across the display and with the emissive regions for the blue pixels forming a relatively larger area of the display than either the red or green pixels.

  • Patent number: 9140430
    Abstract: A light source, for example a light emitting diode, can emit light and have an associated optical axis. The source can be deployed in applications where it is desirable to have illumination biased laterally relative to the optical axis, such as in a street luminaire where directing light towards a street is beneficial. The source can be coupled to an optic that comprises a cavity. At least a portion of the cavity can have an outline that is egg-shaped in cross section. A backside of the cavity (or a backside portion of the optic) can have an irregular shape for receiving the light emitting diode, for example to form a receptacle shaped to fit a circuit board on which the light emitting diode is mounted.
