  • Patent number: 8357556
    Abstract: A method and apparatus are provided for protecting a semiconductor device from damage. The method may include the steps of providing an active semiconductor device on a surface of a semiconductor substrate where the active device is surrounded by an inactive semiconductor area, and providing a soft metallic guard element in the inactive semiconductor area around at least a portion of the periphery of the active device wherein the metallic guard element is connected to ground potential and not to the active device.

  • Patent number: 7397179
    Abstract: A flat panel display reduces the line resistance of a driving power supply line and prevents a voltage drop in the driving power supply line so as to obtain uniform resolution and luminance. The flat panel display includes a substrate, a display region formed on the substrate, the display region having a self-luminescent element and VDD lines that supply a driving potential power and/or a source current to the self-luminescent element. Further, a covering member for sealing the display region at least, the covering member being adhered to the substrate to face the substrate and a terminal region formed on one or more edges of the substrate, the terminal region having one or more driving power terminals are provided. In addition, a driving power supply line that connects the driving power terminals to the VDD lines of the display region and a bus conductive unit that is electrically connected to the driving power supply line are provided.

  • Publication number: 20040007954
    Abstract: The present invention realizes a cathode ray tube which holds the stable electron emission characteristics when the cathode ray tube is operated in a high current density state for a long time. An electron emissive material layer which constitutes a cathode is formed by dispersing a scandium compound having an average particle size of equal to or less than 1.2 &mgr;m to an oxide layer formed of alkaline earth metal (barium, strontium, calcium) oxide, wherein an atomic weight ratio of scandium with respect to strontium is set to a value within a range of 0.003 to 0.3. A base metal includes a reducing metal containing nickel as a main component and a plate thickness of a surface of a top portion of the base metal which comes into contact with the electron emissive layer is set to a value equal to or more than 0.17 mm.

  • Patent number: 6307527
    Abstract: Surface mounted LEDs are arrayed in special patterns to provide a relatively high resolution dot-matrix visual display and/or multi-segment character displays. Especially abbreviated solder bonding pads are utilized to obtain a higher density packing of the surface mounted arrays in at least some embodiments. Special anti-glare coatings and structures are employed to reduce ambient light reflections for aircraft instrument applications. Multi-colored display outputs are also provided.

  • Patent number: 4401919
    Abstract: To achieve an optimum reduction of the warmup time of a Wehnelt cathode, by maintaining a good efficiency, it is proposed to use as a cathode a triode system arranged within the usual cathode sleeve, with the inside of the base plate, on the outside of which the electron-emitting layer is deposited, serving as the anode, so that the electron-emitting layer is heated by the anode dissipation of the triode system.
