Description

간섭 없이 감도가 향상되는 단일 적층 구조를 갖는 터치스크린 패널Touch screen panel with single laminated structure for improved sensitivity without interference
본 발명은 터치스크린 패널에 관한 것으로서, 보다 구체적으로는 간섭 없이 감도가 향상되는 단일 적층 구조를 갖는 터치스크린 패널에 관한 것이다.The present invention relates to a touch screen panel, and more particularly, to a touch screen panel having a single laminated structure in which sensitivity is improved without interference.
터치스크린 패널(touchscreen panel)이란 접촉식 패널이라고도 하는데, 디스플레이에 표시되어 있는 버튼을 접촉함으로써, 대화적이고 직감적인 조작을 가능하게 하여 손쉽게 컴퓨터를 조작할 수 있게 하는 컴퓨팅 입력 장치를 말한다. 정전용량 방식의 터치 패널은 사람의 몸에 있는 정전용량을 이용하는 방식이다. 정전용량 방식의 터치 패널은, 교류 전압을 이용하여 사람의 정전용량에 의해 일어나는 저항과 전류의 변화를 측정하여 터치를 인식하는 방식과, 커패시터의 충전되는 양을 비교하여 터치 유무를 판단하는 방식으로 나눌 수 있다. 이와 같은 정전용량 방식의 터치 패널은, 필름을 사용하는 저항 막 방식에 비해 내구성이 탁월하여 수분이나 작은 손상에도 동작에 지장이 없다. 또한, 터치의 정확도가 비교적 높고, 광학적 특성이 우수하여 화면이 선명하다. 특히, 정전용량의 충전 방식을 이용하는 터치 패널은, 다중 포인트가 가능하고 소형으로 제작이 가능하여 모바일 스마트 기기에 많이 사용되고 있다.A touchscreen panel, also referred to as a touch panel, refers to a computing input device that makes it possible to easily operate a computer by enabling interactive and intuitive operations by touching a button displayed on a display. A capacitive touch panel uses a capacitance in a human body. In the capacitive touch panel, a touch is recognized by measuring a change in resistance and current caused by a capacitance of a person using an alternating voltage, and a method of determining whether there is a touch by comparing the amount of charge of a capacitor. Can be divided. Such a capacitive touch panel is superior in durability compared to a resistive film method using a film, and thus does not interfere with operation even with moisture or small damage. In addition, the touch accuracy is relatively high, and the optical characteristic is excellent, so that the screen is clear. In particular, the touch panel using the capacitive charging method is multi-point and can be manufactured in a small size, which is widely used in mobile smart devices.
종래의 정전용량 방식의 터치 패널은 주로 ITO(Indium Tin Oxide)를 사용하는데, 유리 기판 상부에 ITO를 투명 전극으로 사용하여 터치 신호를 감지하게 된다. 이때, 투명 전극은 2개 층을 사용하여 터치 신호를 감지하고 위치를 검출하는 방법이 사용되고 있으며, 이와 같은 방법이 가장 편리하고 안전한 터치 인식 방식으로 알려져 있다. 그러나 이와 같은 방법은 투명 전극을 2층 이상 사용해야 하므로 제조 단가가 상승하는 단점이 있다. 이와 같은 문제점을 해결하기 위하여, 하나의 투명 전극 층만을 이용하여 2층을 사용하는 것과 같은 효과를 내기 위한 다양한 연구가 시도되고 있다.Conventional capacitive touch panels mainly use indium tin oxide (ITO), and use ITO as a transparent electrode on a glass substrate to sense a touch signal. In this case, a method of detecting a touch signal and detecting a position using two layers is used as the transparent electrode. Such a method is known as the most convenient and safe touch recognition method. However, such a method has a disadvantage in that the manufacturing cost increases because two or more transparent electrodes must be used. In order to solve this problem, various studies have been attempted to produce the same effect as using two layers using only one transparent electrode layer.
도 1은 단일 적층 구조를 갖는 터치스크린 패널의 평면도 구성을 도시한 도면이다. 도 1에 도시된 터치스크린 패널은, 본 출원인에 의해 개발 구현된 단일 적층 구조를 갖는 터치스크린 패널로서, 본 발명의 일실시예에 따른 간섭 없이 감도가 향상되는 단일 적층 구조를 갖는 터치스크린 패널과의 대비를 위해 개량 발명 이전의 구성을 일례로 도시한 것이다.1 illustrates a plan view of a touch screen panel having a single stacked structure. The touch screen panel shown in FIG. 1 is a touch screen panel having a single laminated structure developed and implemented by the present applicant, and has a single laminated structure in which a sensitivity is improved without interference according to an embodiment of the present invention. For the sake of contrast, the configuration before the invention is shown as an example.
도 1에 도시된 바와 같이, 단일 적층 구조를 갖는 터치스크린 패널은, 복수의 패턴센서 감지부(11)와, G1 연결부(12)와, G2 연결부(13)와, 차단 노드(14)와, 베젤부(15)와 베젤 연결부(16)를 구비하는 터치 패널(10), FPCB(20), 및 터치 컨트롤러(30)를 포함하여 구성된다. 이러한 터치스크린 패널은 특정 패턴센서 감지부(11)에 접촉 신호가 입력되면, G1 연결부(12)와 G2 연결부(13)의 그룹 노드 간의 상호 커패시턴스의 측정을 통해 터치를 감지하게 된다. 이때, 터치스크린 패널(TSP)의 투명전극 중에서 패턴센서 감지부(11) 이외에도 G2 연결부(13)와 G1 연결부(12)에 의한 커패시턴스로 인해 간섭 현상이 발생하게 된다. 이러한 간섭 현상을 없애기 위해 커패시턴스 발생을 막는 차단 노드(14)를 사용하게 된다. 패턴센서 감지부(11)의 개수가 증가함에 따라 연결선이 증가하여 패턴센서 감지부(11)의 크기가 작아지고, 터치 감도의 저하가 유발된다. 즉, 간섭 현상을 없애기 위한 shield 또는 다른 노드가 위의 차단 노드(14)의 형태로 추가됨에 따라 G2 연결부(13)가 두꺼워지고, 두꺼운 G2 연결부(13)로 인해 패턴센서 감지부(11)의 감지 영역이 작아져 터치 감도의 저하가 발생하게 된다. 또한 패턴센서 감지부(11)의 개수 증가 시에 G2 연결부(13) 또한 증가되어 패턴센서 감지부(11)의 크기를 작게 만들게 되고, 패턴센서 감지부(11)의 크기가 작아짐으로 인해 터치 감도의 저하가 발생되는 문제점이 있었다.As shown in FIG. 1, the touch screen panel having a single stack structure includes a plurality of pattern sensor detection units 11, a G1 connection unit 12, a G2 connection unit 13, a blocking node 14, The touch panel 10 includes a bezel part 15 and a bezel connection part 16, an FPCB 20, and a touch controller 30. When the touch signal is input to the specific pattern sensor detecting unit 11, the touch screen panel detects a touch by measuring mutual capacitance between the group nodes of the G1 connection unit 12 and the G2 connection unit 13. In this case, an interference phenomenon occurs due to the capacitance caused by the G2 connection part 13 and the G1 connection part 12 in addition to the pattern sensor detecting part 11 among the transparent electrodes of the touch screen panel TSP. In order to eliminate such interference, a blocking node 14 which prevents capacitance generation is used. As the number of the pattern sensor detectors 11 increases, the connecting line increases, so that the size of the pattern sensor detector 11 decreases, and the touch sensitivity is lowered. That is, as the shield or another node to eliminate the interference phenomenon is added in the form of the blocking node 14 above, the G2 connection part 13 becomes thicker, and the thick G2 connection part 13 causes the pattern sensor detection part 11 The sensing area is reduced, resulting in a drop in touch sensitivity. In addition, when the number of the pattern sensor detection unit 11 is increased, the G2 connection unit 13 is also increased to make the size of the pattern sensor detection unit 11 smaller and the touch sensitivity due to the smaller size of the pattern sensor detection unit 11. There was a problem that the degradation of.
