  • Patent number: 8460048
    Abstract: A method for manufacturing a plasma display panel in which an electrical discharge gas is introduced into a space between a first substrate and a second substrate which are sealed together, the method including: a first deaeration step of releasing impurity gases from a protective film by heating the first substrate, on which the protective film is formed for withstanding plasma electrical discharge, to 280° C. or more in a vacuum or in a controlled atmosphere; and a sealing step of sealing the front substrate, in which the impurity gases have been released from the protective film, and a rear substrate which are placed in contact with each other.

  • Patent number: 8454404
    Abstract: A method for manufacturing a sealed panel having a first substrate and a second substrate, including: a melting step of melting a sealing material which does not contain a binder for making the sealing material into paste form; a coating step of applying the melted sealing material onto a surface of the second substrate; and a sealing step of laminating the first substrate and the second substrate via the sealing material applied onto the surface of the second substrate.

  • Publication number: 20120114854
    Abstract: A vacuum processing apparatus has a degassing chamber and does not need a large-sized vacuum evacuation device. In the process of heating and degassing an object to be processed in the degassing chamber, transferring the object to be processed into a processing chamber through a buffer chamber; and performing vacuum processing, the degassing chamber is connected to an vacuum evacuation system having a low evacuation speed and degassing processing is performed in a vacuum atmosphere of 1 to 100 Pa (time 0 to t2). Next, the object to be processed is moved to the buffer chamber, and the pressure inside the buffer chamber is lowered to near the pressure of the processing chamber (time t2 to t3), then the buffer chamber and the processing chamber are connected, and the object to be processed is transferred into the processing chamber.

  • Patent number: 7626337
    Abstract: A plasma display panel 1 of the present invention has a protective film 14 over a sustaining electrode 15 and a scanning electrode 16, with the main components of the protective film being CaO and SrO, and the concentration of the CaO in the protective film 14 is 20 mol % or more and 90 mol % or less. This protective film 14 has a smaller work function than a conventional MgO film so light can be emitted at a lower discharge voltage than in the past. If the discharge voltage is lower, the protective film 14 will be sputtered more slowly so that the service life of the plasma display panel 1 will be longer. Also, since the plasma-gas contains xenon gas, the plasma display panel of the present invention has higher brightness.
