48.触摸屏显示。将X、Y方向的电压场施加于同一层透明导电层ITO，以及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镍金涂层层材料，由于外导电层经常被触摸，所以采用了镍金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轴电压值??对接触点进行时间划分。测量触点位置的方法。ITO内层需要4个引线，外层有5个引线。电容屏的表面涂有一层透明的ITO导电层，电压连接到四个角上。微小的直流电流扩散部分在屏幕表面形成一个均匀的电场。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。红外触摸屏采用密集的红外矩阵在X和Y方向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.
