With Integrant Display Electrode Patents (Class 313/520)
  • Patent number: 8319705
    Abstract: The plasma display device has a display panel having first and second display electrodes and address electrodes, an electrode drive circuit, and a drive control circuit for controlling the electrode drive circuit. The drive control circuit performs a reset drive control, address drive control and sustain drive control in each subfield. The drive control circuit performs an all cell reset drive control which resets all cells in a first subfield out of the plurality of subfields, and an ON cell reset drive control which resets ON cells in a second subfield. At a first temperature T1, an ultimate potential of an slope pulse of the first display electrode is controlled to be a first potential in the ON cell reset drive control, and at a second temperature T2>T1, the ultimate potential is controlled to be a second potential higher than the first potential.

  • Patent number: 6628086
    Abstract: An organic electroluminescence device is provided which is capable of providing light emission lasting time that can be practically used, that is, of improving its light emission life. A light emitting body used in the organic electroluminescence device is made up of a lower electrode layer, a light emitting layer and a transparent electrode layer being stacked in order on a substrate. As a material for the transparent electrode layer, a substance “In2-xSnxO3-y” being a mixture of an oxide of indium with tin is employed as its chief component. A material having hygroscopicity is formed adjacent to the transparent electrode layer. Light emitting element portion made up of the electrode and light emitting material layer is the electroluminescence device.

  • Patent number: 6473061
    Abstract: A PDP drive method capable of restraining the generation of contour noise and making to be high a brightness level. In the PDP drive method, discharging cells on the plasma display panel start simultaneously on a radio frequency discharge by row lines. Next, the radio frequency discharge, which is caused in each discharging cell on the row line, is erased by applying an erasing pulse corresponding to a brightness level of video to the discharging cells on a row line.

  • Patent number: 5235245
    Abstract: A metallic frame for use in a fluorescent display panel having a CIG (chip in glass) structure and containing a driver IC chip in a vacuum chamber. The metallic frame includes a box-type metallic shield covering the IC chip, metallic external leads, and a deformable part coupled between the box-type metallic shield and the metallic external leads. The deformable part deforms more easily than the metallic shield and the leads upon receiving a tensile force. The deformable part is preferably formed at a bent section of the metallic shield or near a shield side end of the metallic external leads. The deformable part preferably consists of two bent or curved elements which are positioned to form a circle, ellipse, or polygon.
