  • Patent number: 7136123
    Abstract: A reflector is incorporated in a liquid crystal display panel for directing light to an optical path from a lamp to a liquid crystal panel, and a high voltage line is directly connected to an electrode of the lamp, but a low voltage line is connected through a conductive pattern formed on the reflector to the other electrode of the lamp, wherein the conductive pattern is formed from a layer of conductive filler printed on the reflector through thermosetting so that the conductive pattern is thick enough to withstand thermal stress without enlargement of the liquid crystal display unit.

  • Patent number: 4725698
    Abstract: A connector device is disclosed which can branch or terminate signal lines for making a mutual connection among a plurality of units. The connector device includes switches between signal line connection terminals so that the connector may serve as both a branch connector and a strap connector. A hook is provided on a body case of the connector device and usable in interlock with the switch. A groove engageable with the hook is formed on a connector element case for external circuit connection so that through the selective engagement of the hook with the groove the element case is prevented from being inadvertently detached from the body case. During the detachment of the element case, the contact pin is placed in a short-circuited state at all times. A terminating connector device is also disclosed which is comprised of a combination of a connector body with first and second connector elements. The connector body includes first and second pairs of terminal.
