Description

정전용량방식 및 감압방식 터치필름Capacitive type and pressure sensitive type touch film
본 발명은 터치필름에 관한 것으로, 특히 정전용량방식 및 감압(저The present invention relates to a touch film, in particular, a capacitive type and a reduced pressure (low
항막)방식 모두 작동 가능한 터치필름에 관한 것이다.It relates to a touch film that can operate both of the anti-film) method.
최근의 휴대폰 또는 스마트폰은 버튼을 누르는 식의 입력방식에서 벗어나 사용자의 접촉만으로 신호 전달이 가능한 정전용량 또는 감압 터치 입력방식이 구현되어 출시되고 있다. 그러나 정전용량 터치 입력방식의 경우 비전도체 물질은 입력이 불가하다는 것과 터치스크린이 파손되었을 때 감압 터치 입력방식에 비해 오작동 가능성이 높다는 단점이 있고, 감압 터치 입력방식은 손가락, 펜 외에도 거의 모든 것을 이용해 화면을 터치할 수 있어 어떤 도구를 활용하든 입력이 가능하다는 장점이 있지만 대체로 화면 선명도가 떨어지고 충격에 약하다는 단점이 있다.Recently, mobile phones or smartphones have been released by implementing a capacitive or pressure-sensitive touch input method capable of transmitting a signal only by a user's contact, away from the input method of pushing a button. However, the capacitive touch input method has disadvantages that it is impossible to input non-conductive materials and that the possibility of malfunction is higher than that of the pressure-sensitive touch input method when the touch screen is damaged, and the pressure-sensitive touch input method uses almost anything other than fingers and pens. Since you can touch the screen, it has the advantage of being able to input whatever tool you use, but it has the disadvantage that the screen's sharpness is generally poor and it is weak against impact.
