Plasma display panel having a gas adsorption member
View Patent ↗A plasma display panel including a gas adsorption member is disclosed. An effort of gas adsorption is obtained sufficiently, and the presence of the gas adsorption member avoids problems at an exhausting operation in exhaust-baking step. The plasma display panel includes a pair of plates opposed to each other with an enclosed discharge space in between. The pair of plates refer to a front plate and a back plate, and at least one of the plates has a communication hole, around which the gas adsorption member having a hole is disposed.
1. A plasma display panel (PDP) comprising:
a pair of plates opposed to each other with an enclosed discharge space in between, and at least one of the plates having a communication hole communicating with inside of the PDP and with an exhaust pipe disposed outside of the PDP, the exhaust pipe including a connecting portion which connects the exhaust pipe to the at least one of the plates having the communication hole and a tubular portion, the connecting portion having a larger average inner diameter than an inner diameter of the tubular portion; and
a gas adsorption member having one or more holes with cross section areas formed therein, the gas adsorption member being movable within the connecting portion of the exhaust pipe and having an outer diameter that is greater than the inner diameter of the tubular portion,
wherein the one or more holes of the gas adsorption member have a combined total cross section area that is greater than a cross section area of the communication hole.
2. The PDP of claim 1 , wherein the one or more holes of the gas adsorption member is a single hole and has a greater cross section area than an inner cross section area of the exhausting pipe.
3. The PDP of claim 1 , wherein a size of the gas adsorption member is greater than an inner diameter of the exhausting pipe and a diameter of the communication hole.
4. The PDP of claim 1 , wherein the one or more holes is a plurality of holes and a composite cross sectional area of the plurality of holes is greater than an inner cross section area of the exhausting pipe.
5. The PDP of claim 1 , wherein the one or more holes includes at least two holes.
