A gate driver 104 driving the gate according to the gate driving signal output from the controller 103, a data driver 105 driving the data according to the data driving signal output from the controller 103, and And a gate controller 106 for controlling the gate tab package 102 and a printed circuit board 107.

도면중 미설명부호 CS는 콘트롤 신호이며, CES는 공통전극신호이고, VS는 영상신호이고, Vcc는 전원을 표시한 것이다.In the drawings, reference numeral CS denotes a control signal, CES denotes a common electrode signal, VS denotes an image signal, and Vcc denotes a power source.

상기에서 데이타 및 게이트 탭패키지(101)(102)의 한쪽 끝부분은 패널(100)에 접촉시키고 다른 한쪽끝부분은 인쇄회로기판(107)에 접촉시킨다.One end of the data and gate tab packages 101 and 102 is in contact with the panel 100 and the other end is in contact with the printed circuit board 107.

이와같이 구성된 일반적인 액정표시장치의 동작을 상세히 설명하면, 영상신호(VS)가 데이타구동부(101)에 입력되며, 제어부(103)는 외부로 부터 입력된 제어신호(CS)에 따라 데이타 및 게이트 구동신호를 출력시킨다.When the operation of the general liquid crystal display device configured as described above is described in detail, the image signal VS is input to the data driver 101, and the controller 103 receives data and gate driving signals according to the control signal CS input from the outside. Outputs

상기 제어부(103)로 부터 출력된 데이타 구동신호에 따라 데이타구동부(1O1)는 구동하여 입력되는 영상신호(VS)를 처리하게 되며 이와같이 처리된 영상신호(VS)를 패널(100)에 인가하게 된다.According to the data driving signal output from the controller 103, the data driving unit 101 drives and processes the input image signal VS, and applies the processed image signal VS to the panel 100. .

한편 상기 영상신호의 스캐닝을 위해 제어부(103)에서 출력된 게이트 구동신호는 게이트구동부(102)에 인가되며, 상기 게이트구동부(1O2)는 게이트 제어부(106)에서 출력된 제어신호에 따라 구동되어 상기 영상신호의 타이밍을 적절히 조절하게 된다.On the other hand, the gate driving signal output from the control unit 103 for scanning the image signal is applied to the gate driver 102, the gate driver 102 is driven in accordance with the control signal output from the gate controller 106 is The timing of the video signal is adjusted appropriately.

그러나 이러한 일반적인 액정표시 장치는 탭패키지에 실장된 데이타 및 게이트 구동회로가 정전기에 매우 취약한 반도체 집적회로로 되어 있으며 각 패드가 분리되어 있어 정전기에 노출된 상태이다.However, such a general liquid crystal display device is a semiconductor integrated circuit in which data and gate driving circuits mounted in a tab package are very vulnerable to static electricity, and each pad is separated and thus exposed to static electricity.

이로인해 장치내 정전기가 발생되면 각 패드사이에 순간적으로 큰 전압차가 발생되어 회로가 파손되며, 이로인해 탭패키지의 보관, 운반 및 액정패널회로에 부착시 정전기로 인해 탭패키지가 손상되는 문제점이 있었다.Due to this, when static electricity is generated in the device, a large voltage difference is generated between the pads at a moment, and the circuit is damaged. This causes the tab package to be damaged due to static electricity when the tab package is stored, transported, and attached to the liquid crystal panel circuit. .

따라서 본 발명의 목적은 탭패키지의 보관, 운반 및 액정패널회로에 부착시 정전기로 인한 탭패키지의 손상을 방지하도록 액정표시장치의 탭패키지 제조방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a method for manufacturing a tab package of a liquid crystal display device to prevent damage to the tab package due to static electricity when the tab package is stored, transported and attached to the liquid crystal panel circuit.
