交互式触摸屏呈现。以x轴发射传感器为例:发送的发射换能器将电信号通过触摸屏控制器电缆成声波能量并将其传输到左边的表面,然后声波能量是反映在一组精密反射条纹在玻璃中传播一个向上均匀的表面,声波能量通过所述屏体表面，所述屏体上部的反射条纹聚集成向右的线并传送到所述x轴接收换能器。接收换能器将返回的表面声波能量转换成电能。信号。发射换能器发射窄脉冲后，声波能量通过不同路径到达接收换能器，最早到达的在最右边，最晚到达的在最左边，这些声波能量的早到和晚到叠加在一起。不难看出，波形信号是宽的。接收到的信号在x轴方向上收集所有通过不同路径返回的声波能量。它们在y轴上有相同的距离，但在x轴上，最远的比率是最近的那个走了最大x轴距离的两倍。因此，该波形信号的时间轴反映的是每个原始波形叠加前的位置，即X轴坐标。 When there is no touch on the transmitted signal and received signal waveforms, the received signal waveform is exactly the same as the reference waveform. When a finger or other object capable of absorbing or blocking the sound wave energy touches the screen, the sound wave energy that the X axis travels upwards through the finger part is partially absorbed, reflecting that the waveform has an attenuation gap on the receiving waveform, that is, at a certain time position. The received waveform attenuates a gap corresponding to the signal blocked by the finger. To calculate the gap position, you must touch the coordinate controller to analyze the attenuation of the received signal and determine the X coordinate from the gap position. After that, the same process of the Y axis determines the Y coordinate of the touch point. In addition to the X and Y coordinates that general touch screens can respond to, the surface acoustic wave touch screen also responds to the third axis Z coordinate, which can sense the user's touch pressure value. The principle is calculated from the attenuation at the received signal attenuation. Once the three axes are determined, the controller passes them to the host. 4.3 surface acoustic wave touch screen features higher definition, good light transmittance. Highly durable and good scratch resistance
