본 발명은 전극구조에 관한 것으로서, 더욱 상세하게는 플라즈마 디스플레이 패널(PDP), 액정 표시소자(LCD), 형광 표시관(VFD), 전계 발광소자(EL), 전계방출(FED) 등의 평판표시소자에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode structure, and more particularly, to flat panel displays such as plasma display panels (PDPs), liquid crystal display devices (LCDs), fluorescent display tubes (VFDs), electroluminescent devices (EL), and field emission (FED) displays. It relates to an element.
일반적인 칼라 PDP는 도 1 에 도시된 바와같이 상부구조와 하부구조로 구성되는데, 상부구조는 상판글라스(1)와, 상기 상판글라스(1)에 형성되는 유지전극과, 상기 유지전극(3) 방전시에 발생한 표면전하를 유지하기 위한 유전체층(4)과, 보호층(5)으로 이루어지고, 하부구조는 하판글라스(2)와, 상기 하판글라스(2) 상에 형성되는 어드레스전극(6)으로 이루어지며, 상기 상판글라스(1)와 하판글라스(2) 사이에는 표면에 형광체(8)가 도포된 격벽(7)이 형성된다.A general color PDP is composed of an upper structure and a lower structure, as shown in FIG. 1, wherein the upper structure includes an upper glass 1, a sustain electrode formed on the upper glass 1, and a discharge of the sustain electrode 3. A dielectric layer 4 and a protective layer 5 for retaining surface charges generated at the time, and the lower structure includes a lower plate glass 2 and an address electrode 6 formed on the lower plate glass 2. The partition wall 7 having the phosphor 8 coated on the surface is formed between the upper glass 1 and the lower glass 2.
이와같이 구성되는 종래 PDP 구조에 있어서, 상기 유지전극은 약 300㎛의 폭을 갖으며 투명전극(3)과 버스전극(3')으로 이루어지는데, 상기 투명전극라인(3)은 양단에 방전전압이 공급되면 해당 방전공간 내부에서 상호 면방전을 일으키고, 상기 버스전극라인(3')은 투명전극라인(3)위에 각각 형성되어 약50~100㎛의 폭을 갖으며 투명전극라인의 저항에 의한 전압강하를 방지한다.In the conventional PDP structure configured as described above, the sustain electrode has a width of about 300 μm and includes a transparent electrode 3 and a bus electrode 3 ′, and the transparent electrode line 3 has a discharge voltage at both ends thereof. When supplied, mutual surface discharge occurs in the corresponding discharge space, and the bus electrode lines 3 'are formed on the transparent electrode lines 3, respectively, having a width of about 50 to 100 µm and a voltage due to the resistance of the transparent electrode lines. Prevent descent.
이러한 전극구조를 갖는 종래 상판글라스 양단에는 도 2 의 (가)와 같이 패드부(10)가 형성되어 전극으로의 전압을 공급하게 된다.A pad portion 10 is formed at both ends of a conventional upper glass having such an electrode structure to supply a voltage to the electrode as shown in FIG.
그러나 도 2 의 (나)에 나타낸 바와 같이 유지전극상의 버스전극(3')은 폭이 50~100㎛이고 패드부(10)에서는 100~200㎛인 반면 패드부로의 절곡부(A)에서는 폭이 약40㎛정도밖에 되지 않으므로 인하여 제조공정중 작업자의 부주의 혹은 외부충격등으로 인하여 절곡부에서 전극이 쉽게 단선되고, 이는 결국 전압공급 불량을 초래하게 되는 문제점이 있었다.However, as shown in (b) of FIG. 2, the bus electrode 3 'on the sustain electrode has a width of 50 to 100 µm and a width of 100 to 200 µm in the pad portion 10, whereas the width of the bus electrode 3' on the sustaining portion A is in the bend portion A to the pad portion. Since only about 40㎛ the electrode is easily disconnected at the bent due to inadvertent or external impact of the worker during the manufacturing process, which has a problem that eventually leads to poor voltage supply.
본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로 단선의 위험이 있는 버스전극의 절곡부 폭을 넓게 형성함으로서, 제조공정시 전극 단선에 의한 제품의 불량을 막도록 하는데 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above, by forming a wide width of the bent portion of the bus electrode which is a risk of disconnection, the object of the present invention is to prevent product defects due to electrode disconnection during the manufacturing process. have.
본 발명을 도 3 및 도 4를 참조하여 이하에서 상세히 설명한다.The invention is described in detail below with reference to FIGS. 3 and 4.
먼저 본 발명에 의한 버스전극의 구조를 살펴보면 도 3 에 도시된 바와같이 상판글라스의 투명전극(100)상에 위치하는 버스전극(103)이 유효부 양단의 패드부(110)까지 연장되고, 상기 연장부를 전압인가부(101)라 칭하면, 상기 전압인가부(101)와 유효부측 버스전극(103)을 연결하는 연결부(102)와 유효부측 버스전극(103)의 경계를 이루는 절곡선(b)을 하나의 단위패드 중심축(104)에서 중심축(104)과 수직(θ1)을 이루도록 하고, 양측으로 갈수록 점차 중심축과의 각(θ2)이 감소하도록 형성하였다.First, referring to the structure of the bus electrode according to the present invention, as shown in FIG. 3, the bus electrode 103 positioned on the transparent electrode 100 of the upper plate glass extends to the pad portion 110 at both ends of the effective portion. When the extension is referred to as a voltage applying unit 101, a bend line b forming a boundary between the connection unit 102 connecting the voltage applying unit 101 and the effective side bus electrode 103 and the effective side bus electrode 103. ) Is formed so as to form a vertical (θ1) with the central axis 104 in one unit pad central axis 104, and gradually decreases the angle (θ2) with the central axis toward both sides.
이러한 본 발명의 구조는 버스전극의 전압인가부측(101) 절곡부(a)의 폭은 단위패드의 중심축(104)에서 양측면으로 가더라도 종래와 동일한 폭을 유지하게 되지만, 유효부측 절곡부(b)의 폭은 중심축(104)에서 양측면으로 갈수록 종래에 비하여 차츰 넓어지게 되며 끝단에서는 도 3 의 점선으로 나타낸 바와같이 종래 길이에 비해 절곡부(b)의 폭에 많은 변화가 생겼음을 알 수 있다.In the structure of the present invention, the width of the bent portion (a) of the voltage applying portion 101 of the bus electrode is maintained at the same width as before even when going from both sides of the central axis 104 of the unit pad. The width of b) becomes wider than the conventional one as it goes from the central axis 104 to both sides, and at the end, as shown by the dotted line in FIG. 3, the width of the bent portion b is larger than that of the conventional length. have.
즉, 단위패드의 중심축(104)에서는 절곡부(b)가 중심축과 수직에 가깝게 되지만 양측면으로 갈수록 중심축(104)과 절곡부(b)가 이루는 각이 차츰 감소하여θ2에 이르게 되는 것이다.That is, in the central axis 104 of the unit pad, the bent portion b becomes close to the vertical axis, but the angle between the central axis 104 and the bent portion b gradually decreases toward both sides to reach θ2. .
이러한 구조로 인하여 단선의 문제가 발생하던 버스전극(103)의 유효부측 절곡부(b)의 폭을 증가시킴으로, 전극의 불량율을 감소시키고 결국 제품의 신뢰성을 향상시키게 되는 것이다.By increasing the width of the bent portion (b) of the effective portion of the bus electrode 103 due to this structure, the problem of disconnection is reduced, thereby reducing the defective rate of the electrode and eventually improving the reliability of the product.
그리고 다른 실시예로 도 4 에 도시된 바와같이 버스전극의 전압인가부(101)의 절곡부(c) 역시 상기와 같이 단위패드의 중심축(104)과 이루는 각(θ3)을 양측 면으로 갈수록 차츰 감소시킴으로 유효부측 버스전극(103)의 절곡부(b)뿐 만 아니라 전압인가부(101)의 절곡부(c)폭을 증가시켜 제품의 신뢰성을 더욱 향상시킬수 있게된다.In another embodiment, as shown in FIG. 4, the bent portion c of the voltage applying unit 101 of the bus electrode also has an angle θ3 formed with the central axis 104 of the unit pad toward both sides as described above. By gradually decreasing the width of the bent portion (c) of the voltage applying portion 101 as well as the bent portion (b) of the effective side bus electrode 103, it is possible to further improve the reliability of the product.
이상 설명한 바와같이 본 발명의 전극구조는 버스전극의 단선에 취약한 절곡부 폭을 증가시킴으로 외부충격이나 제품의 제조공정중 발생하기 쉬운 전극단선을 막아주어 제품의 신뢰성을 향상시키는 효과가 있다.As described above, the electrode structure of the present invention increases the width of the bent portion that is vulnerable to the disconnection of the bus electrode, thereby preventing the external shock or the electrode disconnection that is likely to occur during the manufacturing process of the product, thereby improving the reliability of the product.
