A method of producing a gas discharge panel includes forming a surrounding unit by positioning a first panel and a second panel together with barrier ribs to partition the space between the panels into cells for light emission when charged with a plasma gas and appropriately addressed. An anti-sealing material inflow rib surrounds the barrier ribs. Sealing material is positioned outside the anti-sealing material inflow rib. The pressure inside the surrounding unit is adjusted to be lower than pressure outside the surrounding unit while applying heat to fuse the sealing material between the first panel and the second panel whereby sealing material is prevented from inflowing into the cells between the barrier ribs during production.

Sealing method and apparatus for manufacturing high-performance gas discharge panel

Barrier ribsformed on a back substrate PAare brought into contact with a bonding paste layerhaving an even surface, applying a bonding agent Bd evenly to the tops of the barrier ribs. Furthermore, a gas discharge panel having a structure in which discharge mainly occurs at locations distanced from parts of the panel connected using the bonding agent Bd is realized.

A method is provided to steadily produce a gas discharge panel, such as a PDP, in which a panel and the top of the barrier ribs are in intimate contact in entirety. First a surrounding unit for the gas discharge panel is formed, then a process for sealing the surrounding unit with a sealing material inserted between two panels at the rim is performed while pressure is adjusted so that pressure inside the surrounding unit is lower than pressure outside. With this construction, the panels constituting the surrounding unit are bonded together while they are pressurized from outside. As a result, a panel and the top of the barrier ribs on the other panel are bonded together while they are in intimate contact in entirety. To fully acquire these effects, it is preferable that the adjustment of pressure starts before the sealing material hardens. During, before, or after the sealing step, an energy such as laser beams or ultrasonic waves may be radiated onto the top of the barrier ribs to bond a panel and the top of the barrier ribs in entirety almost without a gap between them.
