투 레이어 방식 정전용량 터치스크린 및 그 제조방법{Two-layer type Touch screen and its method}Two-layer capacitive touch screen and its manufacturing method {Two-layer type Touch screen and its method}

본 발명은 투 레이어 방식 정전용량 터치스크린 및 그 제조방법에 관한 것으로, 더욱 상세하게는 투 레이어 방식 정전용량 터치스크린에 있어서, ITO용 필름에 코팅된 ITO도전층을 하나의 이상의 절연 애칭선을 통하여 정전전극과 정전절연부를 등 간격으로 형성하여, 터치스크린의 제조에 있어서 엇갈리게 겹쳐지는 정전전극 사이의 겹침 구분선으로 인한 선명도 저하를 방지하도록 함을 목적으로 한 것이다.The present invention relates to a two-layer capacitive touch screen and a method of manufacturing the same. More particularly, in a two-layer capacitive touch screen, an ITO conductive layer coated on an ITO film is formed through at least one insulating nickname line. By forming the electrostatic electrode and the electrostatic insulator at equal intervals, an object of the present invention is to prevent sharpness from being reduced due to overlapping division lines between the overlapping electrostatic electrodes in the manufacture of a touch screen.

일반적으로, 터치스크린은 디스플레이에 표시되어 있는 버튼을 손가락으로 접촉하는 것만으로 컴퓨터를 대화적, 직감적으로 조작함으로써 남녀노소 누구나 쉽게 사용할 수 있는 입력장치이다.In general, a touch screen is an input device that can be easily used by anyone of all ages by interactively and intuitively manipulating a computer by simply touching a button displayed on a display with a finger.

이상과 같은 터치스크린은 저항막방식과 정전용량방식, 적외선방식, 초음파 방식 등이 사용되고 있으며 현재로 저항막방식이 대세를 이루고 있고 그 두께를 최소화함에 있어서는 정전용량방식이 사용되고 있다.Resistive film method, capacitive method, infrared method, ultrasonic method and the like are used as the touch screen as described above, and the resistive film method is generally used and the capacitive method is used to minimize the thickness thereof.

여기서, 상기 정전용량방식의 터치스크린은 그 구조가 도전투광판으로 이루어진 ITO판과, 상기 ITO판의 테두리에 은분페인트를 페인트 형성한 전극부와, 상기 전극부의 하부를 절연하는 절연코팅부와, 상기 전극부의 터치로 인한 오동작을 방지하기 위하여 상면에 전극부의 상측에 코팅된 차폐코팅부로 구성되는 것이다.Herein, the capacitive touch screen includes an ITO plate having a conductive transparent plate, an electrode portion having silver powder painted on the edge of the ITO plate, an insulating coating portion for insulating the lower portion of the electrode portion, In order to prevent the malfunction due to the touch of the electrode portion is to consist of a shielding coating portion coated on the upper side of the electrode portion.

그리고, 상기 ITO판은 투광성 수지로 이루어진 ITO용 필름과, 상기 ITO용 필름의 하부에 도전성 물질이 코팅 형성된 ITO도전층으로 구성되는 것으로, 상기 ITO판은 X축의 정전전극을 형성한 X축 ITO판과 Y축의 정전전극을 형성한 Y축 ITO판으로 구성하고 이를 복층으로 형성한 투 레이어(2 layer) 방식으로 개발되어 사용되고 있다.The ITO plate is composed of an ITO film made of a light-transmissive resin, and an ITO conductive layer having a conductive material coated on a lower portion of the ITO film. The ITO plate is an X-axis ITO plate having an X-axis electrostatic electrode formed thereon. And a Y-axis ITO plate formed with a Y-axis electrostatic electrode, which has been developed and used in a two-layer (two layer) method.

이상과 같은 투 레이어 방식의 ITO판의 제조는 ITO용 필름에 도전성 물질을 코팅하여 ITO도전층을 형성하고, 상기 ITO도전층을 애칭작업을 통하여 정전전극을 등 간격을 형성하며 상기 정전전극의 사이에는 애칭작업을 통하여 정전절연부가 형성되게 제조하는 것으로서, X축 ITO판의 정전전극은 Y축 ITO판의 정전전극부의 정전절연부에 위치되게 애칭형성되고, Y축 ITO판의 정전전극은 X축 ITO판의 정전전극부의 정전절연부에 위치되게 애칭형성되는 것이다.The production of the two-layer ITO plate as described above is to form an ITO conductive layer by coating a conductive material on the film for ITO, forming an electrostatic electrode equally spaced through the nicking operation of the ITO conductive layer between the electrostatic electrode The electrostatic insulation is formed to be formed through a nicking operation, wherein the electrostatic electrode of the X-axis ITO plate is etched to be located in the electrostatic insulation portion of the electrostatic electrode portion of the Y-axis ITO plate, and the electrostatic electrode of the Y-axis ITO plate is It is nicknamed to be located in the electrostatic insulating portion of the electrostatic electrode portion of the ITO plate.

그러나, 상기한 바와 같은 종래의 투 레이어 방식 정전용량 터치스크린은 엇갈리게 겹쳐지는 X축의 정전전극과 Y축의 정전전극 사이로 투영되는 정전절연부가 겹침 구분선을 형성하여 선명도가 저하되어 디스플레이되는 영상의 화질이 저하되고, 정전전극의 겹침과정에 있어서 그 겹침이 정밀하지 않으면 상기 구부선의 굵기 편차가 발생하고 이로 인하여 선명도가 균일하지 않은 문제점이 있었다.However, in the conventional two-layer capacitive touch screen as described above, the capacitive insulator projected between the staggered X-axis electrostatic electrode and the Y-axis electrostatic electrode forms an overlapping line, resulting in deterioration of sharpness and deterioration of image quality of the displayed image. If the overlap is not precise in the overlapping process of the electrostatic electrode, the thickness variation of the bend line may occur, thereby causing a problem in that the sharpness is not uniform.

이에, 본 발명은 투 레이어 방식 정전용량 터치스크린의 제조에 있어서 엇갈 리게 겹쳐지는 정전전극에 의하여 형성되는 겹침 구분선으로 인한 선명도의 저하와 정밀한 겹침이 이루어지지 않으므로 인한 겹침 구분선의 굵기 편차로 인한 전체적인 선명도의 편차가 발생하는 문제점을 해결할 수 있도록 한 것이다.Thus, in the manufacture of the two-layer capacitive touch screen, the sharpness of the overlapping line formed by the overlapping capacitive electrodes overlapped and the sharpness of the overlapping line due to the variation in the thickness of the overlapping line due to the lack of precise overlapping are not achieved. This is to solve the problem that the deviation occurs.

즉, 본 발명은 투 레이어 방식 정전용량 터치스크린에 있어서, ITO용 필름에 코팅된 ITO도전층을 하나의 이상의 절연 애칭선을 통하여 정전전극과 정전절연부를 등 간격으로 형성한 것이다.That is, in the two-layer capacitive touch screen, the ITO conductive layer coated on the ITO film is formed at equal intervals through the at least one insulating nickname line.

따라서, 본 발명은 정전전극 사이에 형성되는 정전절연부를 절연 애칭선로 형성함으로써 그 제조에 있어서 엇갈리게 겹쳐지는 정전전극의 겹침 구분선이 애칭되지 않은 정전절연부에 의하여 가려져 선명도가 균일하게 유지되고 정전전극의 엇갈림 겹침 편차에 따른 겹침 구분선의 편차로 인한 전체적인 선명도의 균일성 저하가 방지되는 것이다.Accordingly, the present invention forms an electrostatic insulator formed between the electrostatic electrodes with an insulation nickname line, so that overlapping overlapping lines of the electrostatic electrodes, which are staggered in manufacturing, are covered by an unnicknamed electrostatic insulator to maintain uniform clarity and Deterioration of the uniformity of the overall sharpness due to the deviation of the overlapping line due to the overlap overlap deviation is prevented.
