이 고안은 액정표시장치에 관한 것으로서, 보다 상세하게는 원스크린 구동방식의 액정표시소자의 전극배치를 개선하여 액정표시장치의 테스트시에 발생되는 불량율을 최소화 시키도록한 액정표시장치에 관한 것이다.The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device in which an electrode arrangement of a liquid crystal display device of a one screen driving method is improved to minimize a defect rate generated during a test of the liquid crystal display device.
일반적으로, 원스크린 구동방식의 액정표시장치는 제1도와 같이 액정패널(50)의 상측에 형성된 제1세그먼트 그라스부(30)상에는 제1 세그먼트 전극(35)이 배치되고, 액정패널(50)의 좌측에 형성된 제1 코먼 그라스부(10)상에는 제1코먼 전극(15)이 배치되어 있다.In general, in the one-screen driving type liquid crystal display device, the first segment electrode 35 is disposed on the first segment glass part 30 formed above the liquid crystal panel 50 as shown in FIG. 1, and the liquid crystal panel 50 is disposed. The first common electrode 15 is disposed on the first common glass portion 10 formed on the left side of the.
이와 같이 제1세그먼트 전극(25)과 제1 코먼 전극(15)이 각기 일측 방향에만 패터링되어 있으므로 액정표시장치의 패널의 전기적인 테스트시에 상기 세그먼트 전극과 코먼 전극이 포함되는 ITO 전극의 오픈현상이 발생되고, 액정패널과 TAB LSI의 본딩을 위한 ITO전극의 클리닝 및 본딩 후 리페어(Repair)단계에서 ITO 전극의 오픈현상이 자주 발생되었다.As described above, since the first segment electrode 25 and the first common electrode 15 are patterned only in one direction, the ITO electrode including the segment electrode and the common electrode is opened during the electrical test of the panel of the liquid crystal display. The phenomenon occurred, and the phenomenon of opening of the ITO electrode frequently occurred during the repair and repairing of the ITO electrode for bonding the liquid crystal panel and the TAB LSI and repairing after bonding.
따라서, 많은 제조공정을 통해 제품의 완성단계에서 ITO 전극의 불량에 의해 제품자체가 불량처리되는 비효율적인 문제가 있었다. 이러한 문제는 전체적으로 수율을 크게 떨어뜨리는 원인으로 된다.Therefore, there is an inefficient problem that the product itself is poorly processed by the defect of the ITO electrode at the completion of the product through many manufacturing processes. This problem causes a large drop in yield overall.
이 고안은 이와 같은 문제점을 해결하기 위한 것으로서, 이 고안의 목적은 액정패널의 세그먼트 전극과 코먼 전극을 패널의 상하측과 좌우측에 형성시켜 액정표시장치의 테스트시에는 추가로 형성시킨 전극을 이용하고 액정표시모듈 제작용 전극들은 테스트시에 사용하지 않도록 하여 상기 테스트 단계에서 전극의 오픈현상이 방지되게 한 액정표시장치를 제공하는데 있다.The object of the present invention is to solve the above problems, and an object of the present invention is to form segment electrodes and common electrodes on the upper and lower sides and the left and right sides of the panel. The present invention provides a liquid crystal display device in which electrodes for manufacturing a liquid crystal display module are not used during a test so that an open phenomenon of the electrode is prevented in the test step.
이와 같은 목적을 달성하기 위한 이 고안은, 액정패널의 좌, 우측에 제1, 제2 코먼 전극이 부착형성된 제1, 제2 코먼 그라스부가 형성되고, 액정패널의 상, 하측에 제1, 제2 세그먼트 전극이 부착형성된 제1, 제2 세그먼트 그라스부가 형성된 액정표시장치에 그 특징이 있다.The present invention for achieving the above object is, the first and second common glass portion is formed on the left and right sides of the liquid crystal panel, the first and second common glass is attached, the first and second on the upper and lower sides of the liquid crystal panel The liquid crystal display device having the first and second segment glass portions having the two-segment electrode attached thereto is characterized.
이하, 이 고안에 따른 액정표시장치의 일실시예에 대하여 첨부도면에 따라서 상세히 설명한다.Hereinafter, an embodiment of a liquid crystal display according to the present invention will be described in detail with reference to the accompanying drawings.
제2도는 이 고안에 따른 액정표시장치의 평면구조를 나타낸 것으로서, 액정패널(100)의 상하좌우에 ITO 전극이 부착 형성되는 그라스부가 있고, 이 그라스부는 좌측이 제1코먼 그라스부(10)이며 우측에 제2코먼 그라스부(20)이다.2 shows a planar structure of a liquid crystal display device according to the present invention, wherein a glass portion in which ITO electrodes are attached to the upper, lower, left, and right sides of the liquid crystal panel 100 is formed, and the glass portion is the first common glass portion 10 on the left side. The second common glass part 20 is on the right side.
또한, 상측이 제1 세그먼트 그라스부(30)이고, 하측이 제2 세그먼트 그라스부(40)이다.In addition, the upper side is the first segment glass portion 30, and the lower side is the second segment glass portion 40.
한편, 상기 제1, 제2 코먼 그라스부(10), (20)에는 각기 제1, 제2 코먼 전극(15), (25)이 부착형성되고, 제1, 제2 세그먼트 그라스부(30), (40)에는 각기 제1, 제2 세그먼트 전극(35), (45)이 부착형성된다.Meanwhile, first and second common electrodes 15 and 25 are attached to the first and second common glass parts 10 and 20, respectively, and the first and second segment glass parts 30 are formed. The first and second segment electrodes 35 and 45 are attached to the first and second segments 40 and 40, respectively.
상기 제1, 제2 코먼전극(15), (25)은 전기적으로 동일라인에 대해 상호 연결되있는 구조이며, 상기 제1, 제2 세그먼트 전극(35), (45)은 전기적으로 동일라인에 대해 상호 연결되어 있는 구조이다.The first and second common electrodes 15 and 25 are electrically connected to the same line, and the first and second segment electrodes 35 and 45 are electrically connected to the same line. Are interconnected structures.
여기서, 상기 제1 코먼 전극(15)과 제1세그먼트 전극(35)은 실제 액정표시장치에서 각기 TAB LSI와 연결되어 사용되는 전극이며, 상기 제2코먼전극(25)과 제2 세그먼트 전극(45)은 액정패널(100)의 전기적인 테스트 단계에서 ITO 전극패턴의 오픈 및 쇼트 테스트 등에 사용하도록 한 것이다.Here, the first common electrode 15 and the first segment electrode 35 are electrodes that are connected to the TAB LSI in an actual liquid crystal display, respectively, and the second common electrode 25 and the second segment electrode 45 are used. ) Is used to open and short the ITO electrode pattern during the electrical test step of the liquid crystal panel 100.
따라서, 액정패널(100)의 전기적인 테스트 단계에서 상기 제2 코먼 전극(25)과 제2 세그먼트 전극(45)을 이용하여 전원을 인가하게 되므로 전극에 손상이 발생할 경우에도 실제 액정표시모듈의 제작용 전극인 제1 코먼 전극(15)과 제1 세그먼트 전극(35)은 전혀 손상이 없게 되므로 ITO 전극의 불량에 의한 제품자체의 불량발생이 없게 된다.Therefore, since the power is applied using the second common electrode 25 and the second segment electrode 45 in the electrical test step of the liquid crystal panel 100, the actual liquid crystal display module is manufactured even when the electrode is damaged. Since the first common electrode 15 and the first segment electrode 35, which are the dragon electrodes, are not damaged at all, there is no defect in the product itself due to the defective ITO electrode.
또한, ITO 전극의 크리닝 및 리페어 단계에서 ITO 전극의 오픈이 발생할 경우에는 남은 여분의 코먼 전극과 세그먼트 전극의 재작업을 할 수 있게 된다.In addition, when the ITO electrode is opened during the cleaning and repairing of the ITO electrode, the remaining common and segment electrodes can be reworked.
이와 같이 이상이 없는 코먼 전극과 세그먼트 전극을 TAB LSI와 본딩시키고, 다른 코먼전극과 세그먼트 전극은 솔더 래지스트 처리로 절연층을 형성한다.In this manner, the common electrode and the segment electrode having no abnormality are bonded with the TAB LSI, and the other common electrode and the segment electrode form an insulating layer by solder resist treatment.
이상에서와 같이 이 고안에 따른 액정표시장치에 의하면, 코먼 전극과 세그먼트 전극이 각기 복수로 구비된 것이므로 어느 일측의 전극에 불량이 발생하여도 다른 일측의 전극을 대체 사용할 수 있게 된다.As described above, according to the liquid crystal display device according to the present invention, since the common electrode and the segment electrode are each provided in plural, the electrode on the other side can be used even if a defect occurs in the electrode on either side.
또한, 이와같은 효과를 가지게 되므로 ITO 전극의 전기적인 테스트시에 자주 발생되는 ITO 전극의 오픈현상과 액정패널과 TAB LSI의 본딩을 하기 위한 ITO 전극의 크리닝시와, 리페어 단계에서 일측의 ITO 전극에 오픈현상이 발생되어도 사용이 가능하므로 액정표시장치의 제조시 ITO 전극 불량에 의해 발생되는 제품의 불량율이 최소화되어 수율이 크게 향상되는 효과가 있다.In addition, since such an effect, the open phenomenon of the ITO electrode, which is frequently generated during the electrical test of the ITO electrode, and the cleaning of the ITO electrode for bonding the liquid crystal panel and the TAB LSI, and in the repairing step, Since it is possible to use even if an open phenomenon occurs, the yield rate of the product generated by the ITO electrode defects is minimized during the manufacturing of the liquid crystal display device, thereby greatly improving the yield.
