触摸屏显示48。将X、Y方向的电压场施加于透明导电层ITO的同一层，最外层的镍金导电层(镍金导电层:五线电阻式触摸屏的外导电层采用延性金镍镀层材料，由于外导电层是经常接触的，所以采用金镍材料的延性来延长使用寿命。)它只被用作纯导体。触摸时，x轴和y轴的电压值??的接触点是分时划分的。方法测量接触点的位置。ITO内层需要4根引线，外层需要5根引线。容性屏的表面涂有ITO透明导电层，电压连接到四角。微小的直流电流扩展部分在屏幕表面形成均匀的电场。屏幕会感动的手时,人体作为一个耦合电容器,和当前从屏幕的四个角落收集其他杆形成一个耦合电容触摸的坐标计算的控制器计算当前的触摸位置的相对距离。红外触摸屏红外触摸屏是通过X、Y方向上密集的红外矩阵来检测和定位用户的触摸。 The infrared touch screen is equipped with a circuit board frame on the front of the display. The circuit board arranges infrared transmitting tubes and infrared receiving tubes on the four sides of the screen, one by one to form a horizontal and vertical infrared matrix. When the user touches the screen, the finger blocks the two infrared rays passing through the position, so that the position of the touch point on the screen can be determined. Any touch object can change the infrared on the contact to realize touch screen operation.
