Description
본 발명은 플라즈마 디스플레이 패널(PDP)에 관한 것으로서, 특히 PDP 의 구동시 기판 응력에 의해 발생되는 불량을 해결하기 위한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display panel (PDP), and in particular, to solve defects caused by substrate stress during driving of the PDP.
일반적인 PDP는 도 1 에 도시된 바와같이 상부기판(1)과 하부기판(2)으로 이루어지며, 상부기판(1)의 유지전극(3)과 하부기판(2)의 어드레스전극(4)이 교차되는 지점에서 셀(Cell)을 형성하고, 이러한 셀들이 모여서 하나의 플라즈마 디스플레이 패널(PDP)을 구성하게 된다. 또한 상기 상,하기판의 외곽에는 시일링결합을 위한 프릿시일(5)이 형성된다.As shown in FIG. 1, a general PDP includes an upper substrate 1 and a lower substrate 2, and the sustain electrode 3 of the upper substrate 1 and the address electrode 4 of the lower substrate 2 intersect with each other. Cells are formed at the point where the cells are formed, and these cells are collected to form one plasma display panel (PDP). In addition, the upper and lower substrates, the frit seal 5 for sealing coupling is formed.
도 2 는 기판 사이에 프릿시일(5)이 형성된 단면을 나타낸 것으로 내부의 전극구조는 도시하지 않았다.Fig. 2 shows a cross section in which the frit seal 5 is formed between the substrates and does not show the internal electrode structure.
상기와 같이 구성된 3전극 면방전 플라즈마 표시패널 중 임의의 셀의 화상표시과정은 다음과 같다.The image display process of any cell of the three-electrode surface discharge plasma display panel configured as described above is as follows.
먼저, 해당 유지전극(3)에 방전 개시전압이 공급되면 도 1 의 점선으로 표시된 바와같은 유효면(6) 내에서는 인접한 유지전극간에 면방전이 일어나고 이로 인하여 해당 방전공간의 내부면에 벽전하가 형성된다.First, when the discharge start voltage is supplied to the sustain electrode 3, surface discharge occurs between the adjacent sustain electrodes in the effective surface 6 as indicated by the dotted line in FIG. 1, thereby causing wall charges on the inner surface of the discharge space. Is formed.
그후, 유지전극(3)과 해당 어드레스전극(4)에 어드레스 방전전압이 공급되면 유지전극과 해당 어드레스전극간에 어드레스 방전이 일어나 해당 방전공간 내부에 주입된 방전가스가 전자와 이온으로 전리되면서 자외선이 방출되고, 상기 자외선에 의해 방전공간 내부면에 형성된 형광체층(미도시)이 여기되어 가시광선이 방출되며, 상기 가시광선이 전면기판을 통과하여 외부로 출사되면 외부에서 임의의 셀의발광 즉, 화상표시를 인식할 수 있게된다.Subsequently, when the address discharge voltage is supplied to the sustain electrode 3 and the address electrode 4, an address discharge occurs between the sustain electrode and the address electrode, and the discharge gas injected into the discharge space is ionized by electrons and ions, and ultraviolet rays are emitted. When the visible light is emitted to the outside by emitting the phosphor layer (not shown) formed on the inner surface of the discharge space by the ultraviolet rays, and the visible light is emitted to the outside through the front substrate, Image display can be recognized.
그후, 해당 유지전극에 유지 방전전압이 공급되면 전극라인간에 유지방전이 일어나 임의의 셀의 발광이 일정시간동안 유지된다.After that, when the sustain discharge voltage is supplied to the sustain electrode, sustain discharge occurs between the electrode lines, and light emission of any cell is maintained for a predetermined time.
그러나 상기와 같이 동작하는 PDP 기판구조에 있어서 두장의 상,하기판을 합착하면 프릿시일과 기판사이에 응력차이가 발생하게 되는데, 프릿시일에서는 인장강도가 걸리고 프릿시일과 접한 기판에서는 압축강도가 걸리며, 특히 패널 구동시에는 기판의 중앙부와 주변부 사이간의 온도차이가 생기게 된다. 이와 같은 기판전면의 온도차이가 통상 20℃정도가 되면 열팽창계수가 다른 프릿시일과 기판의 응력차이가 더욱 크게되어 도 3 과 같이 크랙시발점(A)으로 부터 크랙(a)이 발생하는데, 특히 상부기판(101)에서 자주 발생되는 문제점이 있었다.However, in the PDP substrate structure operating as described above, when two upper and lower substrates are bonded together, a stress difference occurs between the frit seal and the substrate. The tensile strength is applied to the frit seal and the compressive strength is applied to the substrate that is in contact with the frit seal. In particular, when the panel is driven, there is a temperature difference between the center portion and the peripheral portion of the substrate. When the temperature difference of the front surface of the substrate is generally about 20 ° C., the stress difference between the frit seal and the substrate having different thermal expansion coefficients becomes larger, so that the crack a occurs from the crack initiation point A as shown in FIG. There was a problem that often occurs in the substrate 101.
본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로 프릿시일과 접해있는 기판의 외측면을 따라 열전도성테이프를 부착시킴으로서, PDP의 구동시 발생되는 온도변화를 기판표면으로 직접 전달되게 하여 기판의 온도변화를 감소시키도록 하는데 목적이 있다.The present invention is invented to solve the problems of the prior art as described above by attaching a thermally conductive tape along the outer surface of the substrate in contact with the frit seal, to directly transfer the temperature change generated when the PDP is driven to the substrate surface To reduce the temperature change of the substrate.

이하, 본 발명을 첨부도면을 참조하여 이하에서 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
먼저 본 발명의 구성을 살펴보면 프릿시일(105)과 접해있는 상,하기판(101,102)의 외측면에 열정도성이 뛰어난 알루미늄(AL)계열의 열전도성테이프(106)를 프릿시일형상과 동일하게 접착시켜 구성하였다.First of all, the structure of the present invention bonds the thermally conductive tape 106 of aluminum (AL) series with superior passion to the outer surfaces of the upper and lower substrates 101 and 102 in contact with the frit seal 105 in the same manner as the frit seal shape. It was configured to.
이와같은 구조를 갖는 본 발명의 기술동작을 살펴보면 다음과 같다.Looking at the technical operation of the present invention having such a structure as follows.
글래스기판 표면에는 압축강도가 걸려있고 프릿시일(105) 표면에는 인장강도가 걸려있는 상태에서 PDP가 구동하면 기판의 온도상승으로 열에의한 기판의 팽창이 일어난다.When the PDP is driven while the compressive strength is applied to the surface of the glass substrate and the tensile strength is applied to the surface of the frit seal 105, the substrate is expanded due to the temperature rise of the substrate.
이때, 프릿시일과 기판의 열팽창계수 차이에 의해 종래기술에서는 시일 표면과 접한 기판면에서 크랙이 발생되고 통상 크랙이 발생하는 형태를 보면 프릿시일과 기판이 접한 부근의 한점이 시발점이 되어 기판의 모서리 끝까지 퍼져나가서 기판전체가 갈라지게 되는데, 본 발명에서는 열전도성 테이프(106)의 부착으로 인해 한 점에서 발생되는 크랙의 시발점이 면으로 확산되면서 크랙의 유발원인인 온도에 의한 영향을 줄일 수 있어 크랙의 발생을 막을 수 있는 것이다.In this case, cracks are generated on the substrate surface in contact with the seal surface due to the difference in the coefficient of thermal expansion between the frit seal and the substrate, and when the crack is generated, a point near the contact between the frit seal and the substrate becomes a starting point and the edge of the substrate. Spreads to the end and the whole substrate is split, but in the present invention, the starting point of the crack generated at one point due to the attachment of the thermally conductive tape 106 is spread to the surface, thereby reducing the influence of temperature causing the crack. This can prevent the occurrence of.
특히, 상기 열전도성 테이프(106)는 종래 크랙이 쉽게 발생되는 상부기판(101) 뿐만 아니라 하부기판(102)면에도 접착시킴으로 효과를 더욱 증대시킬 수 있게된다.In particular, the thermally conductive tape 106 can further enhance the effect by adhering to the upper substrate 101 as well as to the lower substrate 102 surface where cracks are easily generated.
이상 설명한 바와같이 본 발명의 PDP 기판구조는 열전도성 테이프의 부착을 통해 기판의 온도상승으로 인한 기판과 프릿시일간의 응력차이에 의한 크렉발생을 막아주는 효과가 있다.As described above, the PDP substrate structure of the present invention has an effect of preventing crack generation due to stress difference between the substrate and the fritday due to the temperature rise of the substrate through the attachment of the thermally conductive tape.
