본 발명은 좌표입력장치 및 그 제조방법에 관한 것으로서, 더 상세하게는 터치 스크린과 같은 좌표입력장치의 전극을 보다 더 간단하고 용이하게 제작할 수 있도록 된 구조를 갖는 좌표입력장치 및 그 제조방법에 관한 것이다.The present invention relates to a coordinate input device and a method of manufacturing the same, and more particularly, to a coordinate input device having a structure that can be more simply and easily manufactured electrodes of a coordinate input device such as a touch screen will be.

일반적으로, 터치 스크린과 같은 좌표입력장치란 펜, 손가락등에 의하여 접촉된 장소의 좌표를 검출하여 퍼스널컴퓨터등의 시스템에 위치를 알려주는 것을 일컫는다. 이와 같은 좌표입력장치의 일실시예인 터치 스크린의 동작원리를 제1A도 및 제1B도를 참조하면서 살펴보면 다음과 같다. 예를 들어, 터치 스크린의 P지점을 펜 또는 손가락 등으로 접촉하면, 터치 스크린의 상·하부에 형성되어 있는 상부 및 하부 패널의 전극(EL1,2)에 의해 Y축 방향의 위치가 인식되고, 터치 스크린의 좌,우에 형성되어 있는 전극(EL3,4)에 의해 X축 방향의 위치가 인식된다. 즉, 터치 스크린의 P지점을 기준으로 하여 세로방향으로는 도시된 저항(R1,R2)에 의해 인가전압(V)이 분배되고, P지점을 기준으로 하여 가로방향으로는 도시된 저항(R3,R4)에 의해 인가전압(V)이 분배되어 P지점이 인식될 수 있게 된다. 상기와 같이 저항에 의해 인가전압이 분배되는 분배 전압값을 수식으로 표현하면 아래의 공식과 같다. In general, a coordinate input device such as a touch screen refers to detecting a coordinate of a place contacted by a pen, a finger, or the like, and informing a system such as a personal computer. Looking at the operation principle of the touch screen as an embodiment of such a coordinate input device with reference to Figures 1A and 1B as follows. For example, when the P point of the touch screen is touched with a pen or a finger, the position in the Y-axis direction is recognized by the electrodes EL1 and 2 of the upper and lower panels formed on the upper and lower portions of the touch screen. The positions in the X-axis direction are recognized by the electrodes EL3 and 4 formed on the left and right sides of the touch screen. That is, the applied voltage V is distributed by the resistors R1 and R2 shown in the vertical direction with respect to the point P of the touch screen, and the resistances R3, shown in the horizontal direction based on the point P, are distributed. The applied voltage V is distributed by R4) so that the P point can be recognized. As expressed above, the divided voltage value in which the applied voltage is divided by the resistor is expressed by the following formula.
