It relates to a manufacturing method of.
일반적으로 정보를 표시하기 위한 박형의 표시장치로서 플라즈마 디스플레이 패널이 널리 사용되고 있다. 종래의 플라즈마디스플레이패널은, 투명한 표시전극이 다수 형성된 표면그래스 기판(상판)과 그 하부에 결합되는 배면 그래스 기판(하판)을 포함하여 이루어진다.In general, a plasma display panel is widely used as a thin display device for displaying information. The conventional plasma display panel includes a surface glass substrate (top plate) on which a plurality of transparent display electrodes are formed, and a back glass substrate (bottom plate) coupled to the bottom thereof.
종래의 플라즈마디스플레이패널의 제조방법은, 도 1 및 도 2에 도시된 바와 같이, 그래스 파우더와 유기용제로 이루어진 페이스트 상태의 실링그래스(3)를 디스펜서를 이용하여 상판(1) 또는 하판(2)의 모서리를 따라 두르고, 상판과 하판를 서로 합착하기 전에 각각에 대하여 일정 온도로 가소성하여 실링그래스를 소결하여 딱딱한 고체상태가 되도록 한 후, 상판과 하판를 서로 맞대어 다시 로내에서 소성, 건조하여 합착한다. 이어서, 하판(2)의 주입구(4)에 배기관(5)을 합착하여, 배기 및 방전가스를 주입하고, 배기관(5)을 팁오프(Tip-off)한다. 상기 배기관(5)의 팁오프는, 배기관의 끝부분을 유리가 녹는 온도인 800도이상으로 가열하여 녹이고, 녹인 부분을 합착하여 붙인다.In the conventional method for manufacturing a plasma display panel, as shown in Figs. 1 and 2, the sealing plate 3 made of a grass powder and an organic solvent is a top plate 1 or a bottom plate 2 using a dispenser. After joining along the edges of the upper plate and the lower plate, the plastics are calcined at a predetermined temperature to each other to sinter the sealing grass to a hard solid state, and then the upper plate and the lower plate are put together and then fired and dried in the furnace again. Subsequently, the exhaust pipe 5 is joined to the injection port 4 of the lower plate 2 to inject exhaust and discharge gas, and the exhaust pipe 5 is tip-off. The tip off of the exhaust pipe 5 is heated by melting the end of the exhaust pipe to 800 degrees or more, which is the temperature at which the glass melts, and the melted parts are joined together.
이러한 종래의 플라즈마 디스플레이 패널의 제조방법에서는, 하판의 사용유리의 재료 특성상 주입구를 내기가 어렵고 주입구의 가공비가 비싸고, 주입구에 배기관 합착시 열특성에 의한 미세 크랙이나 보이드(void)가 발생하는 문제점이 있었다. 또한 배기관의 팁오프시 열로 인해 유리재료에 깨짐이 발생하고, 공정상 이동시에 외부 물체와의 접촉으로 파손이 발생되는 문제점이 있었다.In the conventional method of manufacturing a plasma display panel, it is difficult to make an injection hole due to the material characteristics of the glass used in the lower plate, and the processing cost of the injection hole is high, and when the exhaust pipe is bonded to the injection hole, fine cracks or voids are generated due to thermal characteristics. there was. In addition, a crack occurs in the glass material due to heat during tip off of the exhaust pipe, and there is a problem in that breakage occurs due to contact with an external object during movement.
본 발명은 이러한 종래기술의 문제점을 해결하기 위한 것으로, 주입구와 배기관을 사용하지 않고 상판/하판의 합착 시링부분의 일부를 방전가스주입구로 활용하는 플라즈마 디스플레이 패널의 제조방법의 제공을 목적으로 한다.The present invention is to solve the problems of the prior art, an object of the present invention is to provide a method of manufacturing a plasma display panel utilizing a portion of the upper and lower plates of the bonding searing portion as a discharge gas inlet without using an inlet and an exhaust pipe.
상기 목적을 달성하기 위하여, 본 발명의 플라즈마 디스플레이 패널의 제조방법은, 상판막공정 및 하판막공정후, 실링재 도포시 실링재의 일부구간을 개구하여, 배기 및 방전가스 주입 후에 상기 개구구간을 실링재로 막고 건조/소성처리하는 것을 특징으로 한다.In order to achieve the above object, in the method of manufacturing the plasma display panel of the present invention, after the upper plate film process and the lower plate film process, a portion of the sealing material is opened at the time of applying the sealing material, and the opening section is made into the sealing material after exhaust and discharge gas injection. It is characterized in that the drying and baking treatment.

3 : 실링 4 : 주입구3: sealing 4: injection hole
5 : 배기관5: exhaust pipe
도 3 내지 도 5는 본 발명에 따른 플라즈마 디스플레이 패널의 제조방법을 나타낸 것으로, 상판(1)의 막공정 및 하판(2)의 막공정후, 실링재(3)을 도포시 일부구간(4)을 개구하여 상기 개구구간(4)을 배기관으로서 사용하여, 배기 및 방전가스 주입 후에, 같은 실링재료(3)로 상기 개구구간(4)을 막고 건조/소성처리한다.3 to 5 illustrate a method of manufacturing a plasma display panel according to the present invention. After the film process of the upper plate 1 and the film process of the lower plate 2, a portion section 4 is opened when the sealing material 3 is applied. By using the opening section 4 as an exhaust pipe, after the exhaust and discharge gas injection, the opening section 4 is blocked with the same sealing material 3 and dried / baked.
이를 보다 상세히 설명하면, 상기 실링재는 상판(1)의 막공정을 끝낸 뒤에 실링페이스트를 디스펜서를 이용하여 상판의 모서리에 바른 다음 385℃ 까지 소성공정을 거친다. 본 발명에 따른 제조방법에서는 상판의 모서리 전체를 실링재로 바르지 않고 일부의 영역은 배기관(방전가스)주입구로 이용한다. 다음에 하판과 합착 소성공정을 거쳐서 실링재가 도포되지 않된 부분을 제외하고 다 붙인다. 방전가스를 이 부분을 통해 주입후 동일한 재료로 실링한다.In more detail, the sealing material is applied to the edge of the top plate using a dispenser after finishing the film process of the top plate 1 and then subjected to a firing process to 385 ℃. In the manufacturing method according to the present invention, the entire edge of the upper plate is not applied as a sealing material, and a part of the area is used as an exhaust pipe (discharge gas) inlet. Next, the bottom plate is bonded together except for the part where the sealing material is not applied through the bonding and baking process. Discharge gas is injected through this part and then sealed with the same material.
이상, 본 발명에 따르면, 주입구와 배기관을 사용하지 않고 상판/하판의 합착 실링부분의 일부를 방전가스 주입구로 활용하므로, 하판 배기관/주입구 불량을 제거할 수 있고, 배기관장착에 따른 비용의 상승 및 문제점을 제거할 수 있다.Above, according to the present invention, since part of the upper and lower plate joint sealing portion is used as the discharge gas inlet port without using the inlet and the exhaust pipe, it is possible to eliminate the failure of the lower plate exhaust pipe and the inlet port, and to increase the cost of installing the exhaust pipe and You can eliminate the problem.
