Field of the Invention The present invention relates to a touch panel, and more particularly, to a touch panel employing a compensation electrode pattern for preventing wire electrode disconnection that employs an ITO compensation electrode pattern in order to prevent disconnection of a wiring part electrode formed of Ag.

도 1은 종래의 터치 패널의 배선 전극들을 보여주는 도면이다. 도시된 바와 같이, 종래의 터치 패널은 ITO 배선 영역(10)과 ITO 액티브 영역(30)이 일체형으로 형성되어 있고, 그 가장자리에 Ag 배선 전극들(20)이 형성되어 있다.1 is a view illustrating wiring electrodes of a conventional touch panel. As shown in the drawing, in the conventional touch panel, the ITO wiring region 10 and the ITO active region 30 are integrally formed, and Ag wiring electrodes 20 are formed at the edge thereof.

이러한 터치 패널에서 ITO 액티브 영역(30)의 특정지점에 손가락이나 다른 물체의 터치가 이루어지면 그 지점으로부터 Ag 배선 전극들(20) 까지의 거리에 따른 저항값을 판독하여 터치 지점의 위치를 알 수 있게된다.In such a touch panel, when a finger or other object is touched at a specific point of the ITO active area 30, the location of the touch point can be known by reading a resistance value according to the distance from the point to the Ag wiring electrodes 20. Will be.

그러나 이러한 종래의 터치 패널은 그 제조 공정 중 Ag 배선 전극 형성 공정에서 단선이 발생하기 쉽다. 도 2는 이러한 종래의 터치 패널의 Ag 배선 전극의 단선 모습을 보여주는 도면이다. 도시된 바와 같이, Ag 배선 전극(20)의 아래에는 부도체인 유리 기판(40)이 존재하므로, Ag 배선 전극 인쇄시에 이물이나 스크린 마스크의 막힘 등으로 단선(open) 영역(25)이 생기는 등의 불량이 발생하기 쉽다.However, such a conventional touch panel is likely to be disconnected in the Ag wiring electrode forming step of the manufacturing process. 2 is a view showing a disconnection state of the Ag wiring electrode of the conventional touch panel. As shown, since the glass substrate 40 which is a non-conductor exists under the Ag wiring electrode 20, an open area 25 may be generated due to clogging of a foreign material or a screen mask during printing of the Ag wiring electrode. Of defects are likely to occur.

또한, 완성된 터치 패널의 제품 사용중에도 Ag 배선 전극(20)의 크랙에 의한 단선 불량도 발생하기 쉽다.In addition, disconnection failure due to cracking of the Ag wiring electrode 20 is also likely to occur even during the use of the finished touch panel.

본 발명은 상기와 같은 문제점을 개선하고자 창안한 것으로, Ag 배선 전극 밑에 단선 보상용 전극 패턴을 형성하여 Ag 배선 전극 인쇄시 이물 혹은 스크린 마스크의 막힘에 단선 및 사용중 Ag 배선 전극의 크랙에 의한 단선이 생기더라도 이를 보상하여 전기적 단선을 방지할 수 있는 배선 전극 단선 방지용 보상 전극 패턴을 채용한 터치 패널을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, by forming an electrode pattern for disconnection compensation under the Ag wiring electrode, when the Ag wiring electrode is printed, disconnection or clogging due to cracking of the Ag wiring electrode is prevented. It is an object of the present invention to provide a touch panel employing a compensation electrode pattern for preventing wire disconnection, which can prevent electrical disconnection even if it occurs.

도 3은 본 발명에 따른 터치 패널의 배선 전극들을 보여주는 도면이다. 도시된 바와 같이, 본 발명에 따른 터치 패널은 유리 기판(400) 상에 오른쪽 가장자리의 ITO 배선 영역(100)과 ITO 액티브 영역(300)이 일체형으로 형성되고, 그 왼쪽과상하부의 가장자리의 Ag 배선 전극들이 형성될 자리에도 ITO 보상 전극 패턴(110)이 형성되며, 오른쪽 가장자리의 ITO 배선 영역(100)과 왼쪽 가장자리의 ITO 배선 영역(110)을 포함하는 ITO 배선 상에 Ag 배선 전극(200)이 형성된 구조를 갖는다.3 is a view illustrating wiring electrodes of a touch panel according to the present invention.

Has a formed structure.

도 4 및 도 5는 각각 도 3의 터치 패널을 제작하기 방법을 설명하기 위한 도면들이다. 그 제작 방법은 다음과 같다.4 and 5 are diagrams for describing a method of manufacturing the touch panel of FIG. 3, respectively. The production method is as follows.

먼저, 도 4에 도시된 바와 같이, 유리 기판(400) 상에 오른쪽 가장자리의 ITO 배선 영역(100)과 ITO 액티브 영역(300)을 일체형으로 형성한다. 이때, 그 왼쪽과 상하부의 가장자리에 Ag 배선 전극들이 형성될 자리에도 ITO 보상 전극 패턴(110)을 함께 형성한다.First, as shown in FIG. 4, the ITO wiring region 100 and the ITO active region 300 at the right edge are integrally formed on the glass substrate 400. At this time, the ITO compensation electrode pattern 110 is formed together with the positions where Ag wiring electrodes are formed at the left and upper and lower edges thereof.

다음에, 도 5에 도시된 바와 같은 Ag 배선 전극(200)들을 앞서 형성된(도 4 참조) 오른쪽 가장자리의 ITO 배선 영역(100)과 왼쪽 가장자리의 ITO 배선 영역(110)을 포함하는 ITO 배선 상에 형성하면 터치 패널이 완성된다.Next, the Ag wiring electrodes 200 as shown in FIG. 5 are formed on the ITO wiring including the ITO wiring region 100 at the right edge and the ITO wiring region 110 at the left edge formed previously (see FIG. 4). When formed, the touch panel is completed.

이와 같이 제작된 터치 패널에서는 도 6에 도시된 바와 같이 제조 공정시 Ag 배선 전극(200)에 단선 영역(250)이 발생하더라도 그 밑에 ITO 보상 전극 패턴(100)이 형성되어 있기 때문에 전기적 단선이 발생하지 않는다.In the touch panel manufactured as described above, although the disconnection region 250 is formed in the Ag wiring electrode 200 during the manufacturing process as shown in FIG. 6, since the ITO compensation electrode pattern 100 is formed thereunder, electrical disconnection occurs. I never do that.

이상 설명한 바와 같이, 본 발명에 따른 배선 전극 단선 방지용 보상 전극 패턴을 채용한 터치 패널은, Ag 배선 전극 밑에 ITO 보상 전극 패턴을 미리 형성하여 둠으로써, Ag 배선 전극 형성 공정시 이물이나 스크린 마스크의 막힘에 의해 단선이 생기거나 완성된 Ag 배선 전극의 크랙에 의한 단선이 생기더라도 전기적 단선을 예방할 수 있는 장점이 있다.As described above, the touch panel employing the compensation electrode pattern for preventing wire electrode disconnection according to the present invention is formed by forming an ITO compensation electrode pattern under the Ag wiring electrode in advance, thereby preventing clogging of foreign matter or screen mask during the Ag wiring electrode forming process. By this, even if disconnection occurs or disconnection due to cracking of the completed Ag wiring electrode, there is an advantage of preventing electrical disconnection.
