触摸信号的频率是由触摸笔发出，触摸笔上有两个按键，按下这两个按键可以输出两个不同频率的信号，分别为k1、k2.触摸笔的作用相当于鼠标，当触摸笔输出一次k1频率时相当于点击一下鼠标左键，输出一次k2频率相当于点击鼠标右键。当触摸笔笔尖与LCD距离≤3~5 cm时，触摸检测装置可感应到触摸信号，这时光标随着触摸笔在LCD上移动。触摸信号频率检测精度的高低是触摸屏是否稳定的关键因素。频率检测电路及仿真结果如图3、图4所示，TOUCH_SIN端为触摸信号输入端，通过施密特触发器，然后信号从FRE端发送到单片机，进行运算处理，计算出触摸信号的频率。利用Multisim软件平台建立出频率检测电路仿真模型，从仿真结果中可以看到，经过处理后的触摸信号转换为具有相同周期T的方波信号，将方波信号传送到微处理器，微处理器在t时间里计算出方波的个数n,则信号的周期T=t/n,频率f=1/T,由此确定触摸信号的频率。
