Claims
- 1. A method of separating a plasma display panel into a front panel and a back panel, comprising:heating said plasma display panel for softening and expanding a bonding material disposed between said front panel and said back panel, said expanding bonding material generating an expanding force; and applying said expanding force to at least one of said front panel and said back panel.
- 2. The method of separating a plasma display panel according to claim 1, further comprising:heating said plasma display panel to a temperature of between 450° C. and 550° C.
- 3. A method of separating a plasma display panel into a front panel and a back panel, comprising:heating said plasma display panel for softening a bonding material used between said front panel and said back panel; and removing said bonding material by means of suction or absorption through a groove provided on at least one of said front panel and said back panel.
- 4. A method of separating a plasma display panel into a front plate and a back plate, comprising:heating or cooling said plasma display panel through a laminated graphite sheet provided on either an upper surface or a side surface of at least one of said two plates.
- 5. A method of separating a plasma display panel into a front panel and a back panel, comprising:immersing said plasma display panel in an etching solution capable of selectively dissolving lead oxide-contained glass bonding the front panel and the back panel; and preventing the etching solution from leaking onto an image display screen by a groove provided in an area between a bonding portion and the image display screen of at least one of the front panel and the back panel.
- 6. The method of separating a plasma display panel according to claim 5, wherein said etching solution contains surface-active agent as an additive.
- 7. A method of separating a plasma display panel into a front panel and a back panel, comprising steps of:immersing said plasma display panel in etching solution capable of selectively dissolving bonding material of the front panel and the back panel; and preventing the etching solution from leaking onto an image display screen by a groove provided in an area between a bonding portion and the image display screen of at least one of the front panel and the back panel.
- 8. The method of separatiing a plasma display panel according to claim 1, wherein said supporting components are inserted between the front panel and the back panel immediately before heating the plasma.
- 9. The method of separating a plasma display panel according to claim 1, wherein said supporting components comprise metallic spacers.
- 10. The method of separating a plasma display panel according to claim 9, wherein said metallic spacers comprise stainless steel.
