Abstract
본 발명은 평판표시장치의 패널과 기판간을 접속하는 신규한 접속구조를 개시한다.The present invention discloses a novel connection structure for connecting between a panel and a substrate of a flat panel display.
패널에는 화소구동을 위해 다수의 전극들이 인출되어 전극패드를 구성하는데 이들을 기판에 접속시키기 위해 커넥터가 사용된다. 그런데 전극의 수가 늘어 피치가 감소되면 전극간에 간섭과 구동노이즈가 발생되어 패널의 고밀도화에 장애가 되었다.In the panel, a plurality of electrodes are drawn out for pixel driving to form an electrode pad, and a connector is used to connect them to a substrate. However, as the number of electrodes increases and the pitch decreases, interference and driving noise are generated between the electrodes, which impedes a high density of the panels.
본 발명에서는 절연막이 전극들의 노출되는 접속위치가 서로 다르도록 적층됨으로써 인접전극들을 서로 전기적으로 분리함으로써 패널의 고밀도화 및 신뢰성 향상을 달성하였다.In the present invention, the insulating film is laminated so that the exposed positions of the electrodes are different from each other, thereby electrically separating adjacent electrodes from each other, thereby achieving high density and improved reliability of the panel.

본 발명은 평판표시장치에 관한 것으로, 더 상세히는 표시패널과 회로기판간을 전기적으로 접속시키는 접속구조에 관한 것이다.The present invention relates to a flat panel display device, and more particularly, to a connection structure for electrically connecting a display panel and a circuit board.
LCD(Liquid Crystal Display)나 PDP(Plasma Display Panel) 등의 평판표시패널(Flat Display Panel)을 이용한 평판표시장치는 전자기기의 경박단소화 경향에 따라 점차 그 사용범위가 확대되고 있다. 이러한 평판표시패널에 화상 등의 고정보밀도의 정보를 표시하기 위해서는 고정된 화소에 의한 세그먼트(segment) 방식이 아니라 매트릭스(matrix)방식으로 구성해야 한다.BACKGROUND OF THE INVENTION Flat display devices using a flat display panel such as an LCD (Liquid Crystal Display) or a plasma display panel (PDP) are gradually being used in accordance with the trend of thin and short electronic devices. In order to display information of high information density such as an image on such a flat panel display panel, it is necessary to configure a matrix method, not a segment method using fixed pixels.
이에 따라 제1도에 도시된 바와 같이, 패널(panel;P)과 회로기판(B)에는 XY방향의 다수의 화소를 선택적으로 구동하기 위해 다수의 전극(G)이 인출되는 바, 이 전극(G)들의 집합을 통칭하여 전극패드(電極 pad:D1,D2)로 부르고 있다.Accordingly, as shown in FIG. 1, a plurality of electrodes G are drawn out to the panel P and the circuit board B to selectively drive the plurality of pixels in the XY direction. The set of G) is collectively called electrode pads (D1, D2).
이와같은 패널(P)을 그 구동회로등이 내장된 기판(B)과 접속하기 위해서는 패널(P)과 기판(B)의 전극패드(D1,D2)간을 상호 접속시켜야 하는 바, 이와같은 전극패드(D1,D2)간의 접속에는 일반적으로 FPC(Flexible Panel Connector)로 불리우는 커넥터(k)가 사용되고 이 커넥터(K)는 유연한 절연재질의 베이스(base)상에 구리등 연성이 큰 금속을 적층하여 복수의 도전전극을 형성한 것으로, 유연하게 절곡될 수 있으므로 점선과 같이 기판(B)을 패널(P)의 하부에 설치하는등 표시장치의 설계에 많은 편의를 주고 있다.In order to connect such a panel P with the substrate B in which the drive circuit and the like are embedded, the panel P and the electrode pads D1 and D2 of the substrate B must be interconnected. The connector (k), commonly called FPC (Flexible Panel Connector), is used to connect the pads (D1, D2). Since a plurality of conductive electrodes are formed and can be bent flexibly, a large amount of convenience is provided in the design of the display device, such as installing the substrate B below the panel P as shown by the dotted line.
그런데, 이와같은 접속구조는 제2도에 도시된 바와같이, 패널(P) 또는 기판(B)의 전극패드(D1,D2)의 전극(G)과 커넥터(K)의 베이스(S)상의 도전전극(T)이 동일한 피치(pitch)로 대응되어 서로 정확히 접합된 상태로 접촉되지 않으면 안된다. 그런데 패널(P)의 고(高) 피치(pitch)화에 따라 전극패드(D1,D2)의 전극(G)수가 점차 증가하게 되므로 전극(G)간의 피치가 좁아지게 되고, 이에따라 대응 전극간의 정확한 접속이 어려워지며 접속면적이 작아 적절한 구동이 곤란하며 노이즈 혼입이 많은 문제가 있었다.By the way, as shown in FIG. 2, the connection structure of the connection structure includes the electrodes G of the electrode pads D1 and D2 of the panel P or the substrate B and the base S of the connector K. FIG. The electrodes T must be in contact with each other at the same pitch and exactly bonded to each other. However, as the number of electrodes G of the electrode pads D1 and D2 gradually increases with the increase of the pitch of the panel P, the pitch between the electrodes G becomes narrower, and accordingly the accuracy between the corresponding electrodes is reduced. The connection became difficult, the connection area was small, proper driving was difficult, and there were many problems of noise mixing.
이와같은 문제점은 평판표시소자의 고해상도화에 큰 장애요인이 되고 있었다.This problem has been a major obstacle to the high resolution of the flat panel display device.
상술한 종래의 문제점을 감안하여 본 발명의 목적은 전극패드의 전극간 피치가 조밀해지더라도 대응전극간의 정확한 접속이 가능한 접속구조를 제공하는 것을 목적으로 한다.It is an object of the present invention in view of the above-mentioned conventional problems to provide a connection structure capable of accurate connection between corresponding electrodes even when the pitch between electrodes of the electrode pad becomes dense.
이러한 목적을 달성하기 위해 본 발명에 의한 접속구조는, 패널과 기판에서 인출된 다수의 전극으로 구성된 전극패드를 구비하는 평판표시장치의 패널 접속구조에 있어서, 전극패드상에 인접전극들의 접속위치가 서로 달라지도록 절연하는 절연막(dieletriclayer)을 교대 형성함으로써, 전극을 그 단부가 상호 전기적으로 절연된 복수의 그룹(group)으로 분리하는 것을 특징으로 한다.In order to achieve the above object, the connection structure according to the present invention is a panel connection structure of a flat panel display device having an electrode pad composed of a plurality of electrodes drawn out of a panel and a substrate. By alternately forming an insulating film (dieletriclayer) to be different from each other, it is characterized in that the electrode is separated into a plurality of groups whose ends are electrically insulated from each other.
이와같은 본 발명 접속구조의 구체적 특징과 다른 이점들은 첨부된 도면을 참조한 이하의 바람직한 실시예의 설명으로 더욱 명확해질 것이다.Such specific features and other advantages of the present invention connection structure will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.
제3도에서, 패널(P)또는 기판(B)의 전극패드(D1)는 상호 소정의 피치로 배열된 전극(G1,G2)들을 구비한다. 이 전극(G1,G2)들은 본 발명 특징에 의해 인접 전극들 간에 그 단부가 서로 전기적으로 절연되는데, 이를 위해 전극패드(D1)의 전극(G1,G2)상에는 절연막(Ⅰ)이 소정의 형상 및 두께로 적층되어 있다. 도면에서 전극(G1,G2)들은 두 그룹으로 구분되는데, 이에 따라 절연막(I)은 절연부(O)또는 노출부(X)가 서로 교열(staggered)되는 형태, 즉 횡방향으로 보았을 때 절연부(0)와 노출부(X)가 반복되는 형태의 두 행(row)으로 형성된다. 예를들어 도면의 좌단에 부재번호가 표기된 두 전극(G1, G2)를 살표보며 최좌단의 전극(G1)은 절연막(I)이 형성되지 않는 노출부(X)가 선단측에 위치하고, 그 다음 전극(G2)은 최좌단전극(G1)의 노출부(X)위치에 절연막(O)이 형성되어 절연부(O)가 되고 그 내측에 절연막(Ⅰ)이 형성되지 않은 노출부(X)가 위치한다. 이 노출부(X)에 노출된 각전극(G1,G2)부분이 활점(active point)들이 되므로 이들이 접속점을 형성하고, 이 접속점은 전극(G1,G2)하나 걸러 동일위치에 형성된다. 이에 따라 인접전극(G1,G2)들간에는 전기적으로 완전히 분리되어 전극패드(D1)와 커넥터(도시안됨)간의 상대위치가 다소 어긋나더라도 인접전극(G1,G2)들간의 전기적 간섭은 전혀 발생되지 않는다.In FIG. 3, the electrode pads D1 of the panel P or the substrate B have electrodes G1 and G2 arranged at a predetermined pitch to each other. The electrodes G1 and G2 are electrically insulated from each other between adjacent electrodes by a feature of the present invention. For this purpose, the insulating film I has a predetermined shape and is formed on the electrodes G1 and G2 of the electrode pad D1. Laminated in thickness. In the drawing, the electrodes G1 and G2 are divided into two groups. Accordingly, the insulating layer I is formed in such a manner that the insulating portion O or the exposed portion X is staggered with each other, that is, when viewed in the transverse direction. (0) and the exposed portion (X) are formed in two rows in a repeating form. For example, at the left end of the drawing, two electrodes G1 and G2 marked with member numbers are shown on the left side, and the leftmost electrode G1 has an exposed portion X at which the insulating film I is not formed is located at the tip side. In the electrode G2, the insulating layer O is formed at the exposed portion X of the leftmost electrode G1 to form the insulating portion O, and the exposed portion X without the insulating layer I formed therein. Located. Since the portions of each electrode G1 and G2 exposed to the exposed portion X become active points, they form connection points, which are formed at the same position every other electrode G1 and G2. Accordingly, even if the relative position between the electrode pad D1 and the connector (not shown) is slightly shifted between the adjacent electrodes G1 and G2, the electrical interference between the adjacent electrodes G1 and G2 does not occur at all. .
이와 같은 본 발명 접속구조는 여러 가지 다양한 응용이 가능한 바, 예를들어, 제4도의 실시예에서는 전극(G1', G2')들이 서로 종단위치가 다른 두 그룹으로 형성되고, 내측그룹의 전극(G2')들상에만 절연막(I')이 적층된다. 이때 내측그룹의 전극(G2')들의 종단에 대응하는 부분에는 절연막(Ⅰ')이 형성되지 않아 창(window)형태의 노즐부(X')를 구성하여, 이 부분이 내측그룹의 전극(G2')들의 접속점이 된다. 이러한 구성은 인접전극(G1', G2')들간의 전기적 분리가 더욱 확실해지므로 그 종단에는 면적이 증대된 접속노드(connecting nod;N)를 형성하여 더욱 확실한 접속을 제공하는 것이 바람직하다.Such a connection structure of the present invention can be variously applied. For example, in the embodiment of FIG. 4, the electrodes G1 'and G2' are formed of two groups having different termination positions from each other, and the electrodes of the inner group ( The insulating film I 'is laminated only on the G2'). At this time, since the insulating film I 'is not formed at a portion corresponding to the end of the electrodes G2' of the inner group, the nozzle portion X 'in the form of a window is formed, and this portion is the electrode G2 of the inner group. ') Is the connection point. In such a configuration, since electrical separation between adjacent electrodes G1 'and G2' becomes more secure, it is desirable to provide a more reliable connection by forming a connecting node N having an increased area at its end.
한편 이러한 접속구조에 사용되는 커넥터는 일반적인 커넥터나 제3도 및 제4도에 대응하는 형태의 절연막을 구비하는 커넥터등이 사용될 수 있으나, 가장 바람직하기로는 본원과 동일자로 출원되는 패널 커넥터(특허출원번호 추후보정)가 사용될 수 있다.The connector used in the connection structure may be a general connector or a connector having an insulating film corresponding to FIGS. 3 and 4, but most preferably a panel connector (patent application) Number correction) can be used.
이와 같이 본 발명에 의하면 전극간의 전기적 분리가 가능하므로 전극의 피치 또는 밀도를 종래보다 2배로 하여도 신뢰성 높은 구동이 가능하게 된다. 뿐만아니라 본 발명은 기존의 접속구도에 부가적으로 실시될 수 있고, 이에 따라 접속불량이나 노이즈 등의 문제를 해결하여 평판표시장치의 신뢰성을 향상 시킬수 있게 된다.As described above, according to the present invention, electrical separation between the electrodes is possible, so that a reliable driving is possible even if the pitch or density of the electrode is doubled. In addition, the present invention can be implemented in addition to the existing connection configuration, thereby improving the reliability of the flat panel display by solving problems such as poor connection or noise.
이와 같이 본 발명은 평판표시장치의 고해상도화와 신뢰성 향상에 큰 효과가 있다.As described above, the present invention has a great effect in increasing the resolution and reliability of the flat panel display.
