Description

PDP의 하판구조 및 제조방법Bottom plate structure and manufacturing method of PDP

본 발명은 플라즈마 디스플레이 패널(PDP)에 관한 것으로서, 특히 하부기판상에 격벽 및 형광체를 형성하기위한 PDP의 하부기판 구조 및 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display panel (PDP), and more particularly, to a lower substrate structure and a manufacturing method of a PDP for forming partition walls and phosphors on a lower substrate.

일반적인 PDP의 구조를 살펴보면 도 1 에 도시된 바와같이 두 개의 나란한 절연기판(1,2)중 하부기판(1)에는 하부전극(4) 및 격벽(7)이 형성되고, 상기 격벽(7)사이에는 R,G,B 각각의 형광체(8)가 도포되며, 상부기판(2)에는 나란하게 배열된 한쌍의 유지전극(3)이 배열되고, 상기 유지전극(3)위에는 유전층(5)이 형성되게 된다.Referring to the structure of a general PDP, as shown in FIG. 1, a lower electrode 4 and a partition wall 7 are formed on a lower substrate 1 of two parallel insulating substrates 1 and 2, and between the partition walls 7. Phosphors 8 of R, G, and B are coated on the substrate, and a pair of sustain electrodes 3 arranged side by side are arranged on the upper substrate 2, and a dielectric layer 5 is formed on the sustain electrodes 3. Will be.

도면중 미설명 부호 6 은 보호층을 나타낸다.In the figure, reference numeral 6 denotes a protective layer.

이와같이 구성되는 PDP는 유지전극(3)과 하부전극간(4)에 100볼트 이상의 전압을 인가하고, 가스를 글로우방전시켜서 그 때의 발광을 이용하여 표시한다.The PDP configured in this manner is applied with a voltage of 100 volts or more between the sustain electrode 3 and the lower electrode 4, glow discharges the gas, and displays the light using the light emitted at that time.

종래 격벽의 형상은 폭이 약 100미크론, 높이가 100미크론 이상이고, 20인치칼라의 경우에는 640x480의 표시셀의 제품이 시판되며 격벽의 수는 640x3개의 격벽으로 형성되어 있다.The conventional bulkhead has a width of about 100 microns and a height of 100 microns or more, and in the case of 20-inch color, products of 640x480 display cells are commercially available, and the number of partitions is 640x3.

상기 프라즈마 디스플레이 패널의 격벽 형성방법으로는 프린팅법, 샌드브라스트법, 직접 에칭법 등이 사용되고 있으며, 상기 프린팅법은 기판유리의 공정중 변형으로 인하여 마스크 얼라인 등의 불일치로 여러층을 프린팅하여 쌓는데 많은 어려움이 있다. 따라서 직접 에칭법을 사용하고 있는데 이는 도 2에서 보는 바와 같이 하부기판(1)의 상부로 전극층(4)을 형성하고 P/R도포, 노광, 현상 에칭의 순으로 하여 전극을 형성한다.As the barrier rib forming method of the plasma display panel, a printing method, a sand blasting method, a direct etching method, and the like are used, and the printing method prints a plurality of layers due to mismatches such as mask alignment due to deformation of the substrate glass during the process. There are many difficulties in stacking. Therefore, the direct etching method is used. As shown in FIG. 2, the electrode layer 4 is formed on the lower substrate 1 and the electrodes are formed in the order of P / R coating, exposure, and developing etching.

이후 상기 전극의 상부에 격벽형성물질(10)을 50∼80미크론 정도 도포하여 건조시킨 후 드라이 필름(11)을 라미네이팅 한다.Thereafter, the barrier rib forming material 10 is applied to the upper portion of the electrode by about 50 to 80 microns, dried, and the dry film 11 is laminated.

그 다음 마스크를 대고 UV에 노광시킨 후 현상공정에서 현상시켜 패턴을 형성하고 다시 샌드(CaCo3)로 때리는 에칭공정(7)을 통해 격벽을 형성한다.Then, the mask is exposed to UV and then developed in a developing process to form a pattern, and then a partition wall is formed through an etching process 7 hitting with sand (CaCo 3).

상기 에칭공정(7)은 박리액에서 100∼300초 동안 에칭을 행하고 세정을 행한 후 로에 넣어 200∼500도 사이에서 20∼60분 동안 소성시켜 격벽을 형성한 후 드라이필름(11)을 제거하고, 격벽 사이에 형광체를 인쇄하게 된다.The etching step (7) is performed by etching for 100 to 300 seconds in a stripping solution, and then washed and then put into a furnace and fired for 20 to 60 minutes between 200 to 500 degrees to form a partition wall to remove the dry film 11 The phosphor is printed between the partition walls.

그러나 이러한 종래 격벽형성공정은 로에서 소성공정을 거치는 동안 기판에 변형이 발생하게 되는데, 이는 형광체의 인쇄시 얼라인(Align)이 어렵게 되어 제품의 신뢰성을 떨어뜨리게 되는 문제점이 있었다.However, such a conventional partition wall forming process causes deformation of the substrate during the firing process in the furnace, which makes it difficult to align when printing the phosphors, thereby lowering the reliability of the product.

본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로 하부기판에 격벽 형성후 드라이필름을 벗겨내지 않은 상태에서 형광체를 인쇄하고 드라이필름을 벗겨낸 후 소성공정을 거치도록 함으로서, 형광체 인쇄시 얼라인이 용이하도록 하여 미스 얼라인으로 인한 제품의 오동작을 방지하고 드라이필름 대신 블랙쉬트를 사용함으로 별도의 BM도포공정을 생략하는데 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above by printing a phosphor in a state in which the dry film is not peeled off after forming the barrier rib on the lower substrate, and peeled off the dry film to undergo a firing process, the phosphor It aims to omit the separate BM coating process by using black sheet instead of dry film by preventing misalignment due to misalignment by making alignment easy during printing.

본 발명을 도 3 및 도 4 를 참조하여 이하에서 설명한다.The invention is described below with reference to FIGS. 3 and 4.

먼저 본 발명에 의한 PDP기판의 제조방법을 살펴보면 도 3 에 도시된 바와같이 하부기판(101)의 상부로 전극층(104)을 형성하고 P/R도포, 노광, 현상 에칭의 순으로 하여 전극을 형성한다.First, referring to the method of manufacturing a PDP substrate according to the present invention, as shown in FIG. 3, the electrode layer 104 is formed on the lower substrate 101 and the electrodes are formed in the order of P / R coating, exposure, and development etching. do.

이후 상기 전극의 상부에 격벽형성물질(110)을 50∼80미크론 정도 도포하여 건조시킨 후 드라이 필름(111)을 라미네이팅 한다.Thereafter, the barrier rib forming material 110 is applied to the upper portion of the electrode by about 50 to 80 microns, dried, and the dry film 111 is laminated.

그 다음 마스크를 대고 UV에 노광시킨 후 현상공정에서 현상시켜 패턴을 형성한 후 다시 샌드(CaCo3)로 때리는 에칭공정(7)을 통해 격벽(107)을 형성한다.Then, the mask is exposed to UV and then developed in a developing step to form a pattern, and then the partition wall 107 is formed through an etching step 7 of hitting with sand (CaCo 3).

상기 에칭공정(7)은 박리액에서 100∼300초 동안 에칭을 행하고 세정을 행한 후 형광체(108)를 인쇄한다. 그리고 격벽(107) 상부에 잔존하는 드라이 필름(111)을 벗겨낸후 로에 넣어 550∼600도 사이에서 20∼60분 동안 소성시켜 하판글라스를 완성하게 되는 것이다.In the etching step 7, the etching solution is etched for 100 to 300 seconds in the stripping solution, washed, and the phosphor 108 is printed. Then, the remaining dry film 111 on the partition 107 is peeled off and put into a furnace to be fired for 20 to 60 minutes between 550 to 600 degrees to complete the bottom glass.

상기 드라이 필름(111) 제거하는 방법은 종래의 박리액에 녹여서 할 경우 형광체를 오염시키고 충격을 주게 되므로 테이프 혹은 기계적으로 부착하는 방법을 사용한다.The method of removing the dry film 111 uses a method of attaching a tape or mechanically because it melts in a conventional peeling solution and contaminates a phosphor and gives an impact.

이러한 본 발명의 제조방법은 격벽(107) 형성후 소성하지 않은 상태에서 형광체 R,G,B를 인쇄함으로 격벽을 튼튼하게 유지하여 인쇄시에 격벽재가 보호되도록 하고, 얼라인을 쉽게 구현할 수 있는 것이다.The manufacturing method of the present invention is to maintain the barrier ribs by printing the phosphors R, G, B in the unfired state after the barrier rib 107 is formed so that the barrier ribs are protected during printing, and the alignment can be easily implemented. .

그리고 다른 실시예로 도 4 에 나타낸 바와같이 드라이 필름 대신 BM역할을 위한 블랙쉬트(112)를 격벽형성물질(110)위에 부착하면, 별도의 격벽(107)의 상면에 형성되는 BM도포공정을 생략할 수 있으므로 제품의 제조공정을 단순화 할 수 있게된다.In another embodiment, as illustrated in FIG. 4, when the black sheet 112 for the BM role is attached to the partition forming material 110 instead of the dry film, the BM coating process formed on the upper surface of the separate partition 107 is omitted. As a result, the manufacturing process of the product can be simplified.

이상 설명한 바와같이 본 발명의 제조방법은 글래스 변형에 의한 미스얼라인을 방지하여 오동작을 막아주고, 격벽재가 박리액에 의해 오염되지 않도록 하여 제품의 신뢰성을 향상시키는 효과가 있다.As described above, the manufacturing method of the present invention prevents misalignment due to glass deformation, thereby preventing malfunction, and prevents the partition wall material from being contaminated by the peeling liquid, thereby improving the reliability of the product.
