엘씨디 패널의 데이터 오픈 리페어 라인의 패턴 구조{PATTERN STRUCTURE OF DATA OPEN REPAIR LINE OF LCD PANEL}Pattern structure of data open repair line of LCD panel {PATTERN STRUCTURE OF DATA OPEN REPAIR LINE OF LCD PANEL}

본 발명은 LCD 패널의 데이터 라인 오픈시 리페어 라인의 패턴 구조에 관한것으로, 보다 상세하게는, 데이터 라인 오픈시 리페어 수단으로 사용하는 리던던시 라인을 데이터 라인과 같은 구성물질 및 패턴으로 제조한 LCD 패널의 데이터 라인 오픈시 리페어 라인의 패턴구조에 관한 것이다.The present invention relates to a pattern structure of a repair line when opening a data line of an LCD panel, and more particularly, to an LCD panel in which a redundancy line used as a repair means when a data line is opened is made of the same material and pattern as a data line. It relates to a pattern structure of a repair line when opening a data line.

LCD 패널에서 데이터 라인과 리던던시 라인 및 그 접속부를 동일 물질로 하지 않을 경우 임피던스 매칭이 되지 않아 데이터 신호가 접속부에서 손실되어 리던던시 라인을 경유하여 최종 데이터 오픈된 포인트까지 신호가 원활하게 들어오지 못하게 된다.If the data line, the redundancy line and the connection part of the LCD panel are not made of the same material, impedance matching is not performed, and thus the data signal is lost at the connection part, and thus the signal does not flow smoothly to the final data open point via the redundancy line.

또한 데이터 신호가 지나가는 전류 경로를 보면, 리던던시 라인이 데이터 라인보다 폭이 크다. 이 경우 저항이 적을 수 있지만 캐패시턴스가 커서 임피던스가 커지므로, 데이터 오픈 지점까지 리던던시 라인을 경유하여 들어온 데이터 신호 파형은 왜곡된다.Also, when looking at the current path through which the data signal passes, the redundancy line is wider than the data line. In this case, the resistance may be small, but the capacitance is large, so the impedance is large, and thus the data signal waveform introduced through the redundancy line to the data open point is distorted.

본 발명의 목적은 상기한 바와 같은 종래기술에 있어서의 문제점을 개선하기 위하여 안출한 것으로, LCD 패널 제조공정에서 리던던시 라인과 데이터 라인 및 그 접속부 구성물질을 동일하게 하여 데이터 신호가 리던던시 라인을 경유할 때 데이터 신호가 100% 전달될 수 있도록 임피던스 매칭이 이루어지도록 한 LCD 패널의 데이터 리페어 라인의 패턴 구조를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to solve the problems in the prior art as described above. In the LCD panel manufacturing process, the redundancy line, the data line, and its connecting component are made the same so that the data signal passes through the redundancy line. The present invention provides a pattern structure of a data repair line of an LCD panel in which impedance matching is performed so that 100% of a data signal can be transmitted.

또한 리던던시 라인의 넓이(WIDTH)를 데이터 라인의 넓이와 동일하게 함으로써, RC 딜레이를 줄여 데이터 신호를 왜곡없이 리던던시 라인을 경유 데이터 오픈 라인까지 원활히 올 수 있도록 한 LCD 패널의 데이터 리페어 라인의 패턴 형성을 제공하는데 있다.In addition, the width of the redundancy line (WIDTH) is equal to the width of the data line, thereby reducing the RC delay to form a pattern of the data repair line of the LCD panel to smoothly come to the data open line via the redundancy line without distortion of the data signal To provide.

상기한 바와 같은 목적을 달성하기 위한 본 발명의 바람직한 실시예에 따르면, LCD 패널에 있어서, 데이터 라인과 리던던시 라인 및 그 접속부를 동일물질로 구성하고, 리던던시 라인과 데이터 라인의 넓이는 최적 임피던스 매칭이 될 수 있도록 동일한 넓이로 구성하고, 상기 데이터 라인과 리던던시 라인의 접속부는 모두 동일한 물질로 구성된 것을 특징으로 하는 LCD 패널의 데이터 오픈 리페어 라인의 패턴구조가 제공된다.According to a preferred embodiment of the present invention for achieving the above object, in the LCD panel, the data line and the redundancy line and the connection portion is made of the same material, the width of the redundancy line and the data line is the optimum impedance matching The pattern structure of the data open repair line of the LCD panel is provided in the same width so as to be possible, and the connection portion of the data line and the redundancy line are all made of the same material.

또한, 상기 리던던시 라인은 상기 데이터 라인과 2줄로 구성된 것을 특징으로 한다.The redundancy line may include the data line and two lines.

이하 본 발명에 따른 LCD 패널의 데이터 오픈 리페어 라인의 패턴구조에 대하여 첨부도면을 참조하여 상세히 설명한다.Hereinafter, a pattern structure of a data open repair line of an LCD panel according to the present invention will be described in detail with reference to the accompanying drawings.

도 1 은 본 발명에 따른 LCD 패널에서의 데이터 라인과 리던던시 라인을 가진 패널의 평면도로서, 이에 도시한 바와 같이, LCD 패널(100)에 있어서, 데이터 라인(30)과 리던던시 라인(20) 및 그 접속부(40)를 동일물질로 구성한다. 따라서, 리던던시 라인(20)과 데이터 라인(30)의 넓이는 최적 임피던스 매칭이 될 수 있도록 한다.1 is a plan view of a panel having data lines and redundancy lines in an LCD panel according to the present invention. As shown therein, in the LCD panel 100, the data lines 30 and redundancy lines 20 and their The connecting portion 40 is made of the same material. Therefore, the width of the redundancy line 20 and the data line 30 can be the optimum impedance matching.

데이터 패드(10)로부터 데이터 신호가 출력되어 데이터 라인(30)으로 각각 입력될 때, 데이터 오픈된 구간에서는 신호가 들어가지 않게 됨으로써 정상 모드에서는 R.G.B 패넌에서 적색이나 녹색 혹은 파랑색으로 데이터 라인이 보이게 된다.따라서 데이터 오픈된 라인을 레이저 리페어 할 경우 데이 신호가 리던던시 라인(20)을 통하여 데이터 오픈된 포인트까지 신호가 들어갈 수 있게 된다. 참고부호 c와 p는 각각 라인 컷팅부와 데이터 오픈부를 나타낸다.When data signals are output from the data pad 10 and input to the data lines 30, the signals are not input in the data open section, thereby making the data lines visible in red, green, or blue in the RGB pann in the normal mode. Therefore, when laser repairing the data open line, the signal can enter the data open point through the redundancy line 20. Reference numerals c and p denote line cutting portions and data opening portions, respectively.

도 2 는 데이터 신호파형을 나타낸 파형도로서, 이에 도시한 바와 같이, 임피던스 매칭이 되지 않을 경우 원래의 데이터 신호파형은 왜곡되어 데이터 신호 왜곡파형으로 나타난다.2 is a waveform diagram illustrating a data signal waveform. As shown in FIG. 2, when impedance matching is not performed, the original data signal waveform is distorted to appear as a data signal distortion waveform.

도 3 은 본 발명에 따른 리던던시 라인이 형성된 패널을 나타낸 평면도로서, 이에 도시한 바와 같이, 데이터 라인(30)의 넓이는 w1이고, 리던던시 라인(20)의 넓이 w2이며, 본 발명에서 w1과 w2는 서로 동일하게 형성되었고, 데이터 라인(30)과 리던던시 라인(20) 및 접속부(40)는 모두 동일한 물질로 형성된다.3 is a plan view showing a panel on which redundancy lines are formed according to the present invention. As shown therein, the width of the data line 30 is w1, the width w2 of the redundancy line 20, and w1 and w2 in the present invention. Are formed identically to each other, and the data line 30, the redundancy line 20, and the connecting portion 40 are all formed of the same material.

상기 설명한 바와 같이 본 발명에 따른 LCD 패널의 데이터 오픈 리페어 라인의 패턴구조에 의하면, LCD 패널의 데이터 라인 오픈시 리페어를 하게 되는 경우, 데이터 신호가 지나가는 경로(리던던시 라인)와 데이터 라인 및 그 접속부의 구성물질을 동일하게 함으로써 임피던스 매칭이 가능하며, 전류 경로의 넓이(WIDTH)를 동일하게 함으로써 RC 딜레이를 줄이는 효과가 있다.As described above, according to the pattern structure of the data open repair line of the LCD panel according to the present invention, when a repair is performed when the data line of the LCD panel is opened, a path (redundancy line), a data line through which the data signal passes, the data line and the connection portion thereof Impedance matching is possible by making the materials the same, and the RC delay is reduced by making the width of the current path (WIDTH) the same.

또한, LCD 패널에서 데이터 라인 오픈 불량 발생으로 인한 손실분을 리페어 함으로써 제조 원가를 낮출 수 있는 효과가 있다.In addition, it is possible to reduce the manufacturing cost by repairing the loss caused by the data line open failure in the LCD panel.

리던던시 라인을 이용한 데이터 오픈 리페어시 임피던스 감소의 효과가 있다.Impedance reduction in data open repair using a redundancy line has an effect.

RC 딜레이에 의한 파형 왜곡수준이 감소되는 효과가 있다.The waveform distortion level due to the RC delay is reduced.
