Description
본 고안은 터치스크린에 관한 것으로, 더욱 자세하게는 정전 용량 터치 스크린에 관한 것이다.The present invention relates to a touch screen, and more particularly to a capacitive touch screen.
정전 용량 터치 스크린은 하나의 구동IC를 구비하는데, 현재 사용되는 종래의 정전용량 터치 스크린의 구동IC는 연성회로기판(FPC) 상에 장착되는데, 연성회로기판이 장착되는 기재는 유리(GLASS) 또는 박막 필름(FILM)이 된다. 종래 기술의 설계방식에 따른 경우 연성회로기판의 크기는 매우 크며, 디스플레이 모듈이 장착되면 매우 큰 공간을 점유하게 되어, 제품의 설계 난이도가 높아지게 되고 전체 제품의 설계 비용이 상승하게 된다.The capacitive touchscreen has one driver IC. The driver IC of the conventional capacitive touchscreen currently used is mounted on a flexible printed circuit board (FPC). The substrate on which the flexible circuit board is mounted is made of glass And becomes a thin film (FILM). According to the conventional design method, the size of the flexible circuit board is very large, and when the display module is mounted, a very large space is occupied, so that the designing difficulty of the product is increased and the design cost of the entire product is increased.
본 고안의 목적은 종래기술이 가지고 있는 전술한 문제점을 보완하는 개선된 정전용량 터치 스크린을 제공하는 것으로, 구조가 단순하고, 점유공간이 작은 특징을 가지고 있다. The object of the present invention is to provide an improved capacitive touch screen which overcomes the above-mentioned problems of the related art, and has a simple structure and a small occupied space.
전술한 목적을 달성하기 위하여, 본 고안이 제공하는 개선된 정전 용량 터치 스크린은 기재(base material), 구동IC, ITO회로, 연성회로기판(FPC)을 포함하여 구성되는데, 여기서 상기 구동IC는 직접 기재 패널 상에 장착되고, 리드(lead)는 기재 패널 외부로 방출된다.In order to achieve the above object, an improved capacitive touch screen provided by the present invention comprises a base material, a driving IC, an ITO circuit, and a flexible circuit board (FPC) Is mounted on the base panel, and the lead is emitted to the outside of the base panel.
전술한 기재는 유리 또는 박막 필름이 된다. The above-described substrate is a glass or a thin film.
전술한 ITO회로는 단층 또는 복층이 된다.The above-mentioned ITO circuit may be a single layer or a multilayer.
본 고안에 따른 정전용량 터치 스크린의 구동IC는 직접 기재 패널 상에 장착됨으로써 터치스크린의 연성회로기판 크기가 작아지게 되고, 연성회로기판은 단지 몇 가닥의 선을 잡아당기기만 하면 된다. 단일 패널은 설계가 간단하게 되어, 터치스크린이 전체 제품에서 점유하는 공간이 대폭 작아지게 되어 공간 절약형 제품설계가 가능하게 됨으로써 설계 및 생산 비용을 절감시킬 수 있다. The driving IC of the capacitive touch screen according to the present invention is mounted directly on the substrate panel, so that the size of the flexible circuit board of the touch screen is reduced. The flexible circuit board is only required to pull out a few wires. The single panel simplifies the design, and the space occupied by the touch screen in the entire product is significantly reduced, which enables space-saving product design, thus reducing design and production costs.
도 1은 본 고안에 따른 정전용량 터치 스크린의 설명도이다.1 is an explanatory diagram of a capacitive touch screen according to the present invention.
이하에서는 실시예를 통해서 본 고안의 기술적 특징을 설명하도록 한다. 다만 여기서 주의해야 할 것은 상기 실시예는 본 고안의 보호범위를 제한하기 위해 사용되어서는 안된다는 것이다.Hereinafter, technical features of the present invention will be described by way of examples. It should be noted, however, that the above embodiments should not be used to limit the scope of protection of the present invention.
도 1에 도시된 바와 같이, 본 고안이 제공하는 정전용량 터치 스크린은, 기재(10), 구동IC, ITO회로, 연성회로기판(도면에 미도시)을 포함하여 구성된다. 여기서, 기재(10)는 유리 또는 박막 필름이 되며, ITO회로는 단층 또는 복층이 되며, 구동IC(20)는 직접 기재(10) 패널 상에 장착되고, 리드(21)는 기재(10) 패널 외부로 방출된다.As shown in Fig. 1, the capacitive touch screen provided by the present invention comprises a substrate 10, a driving IC, an ITO circuit, and a flexible circuit board (not shown). Here, the substrate 10 is a glass or a thin film, and the ITO circuit is a single layer or a multilayer. The driving IC 20 is directly mounted on the panel 10, And is discharged to the outside.
