touch screen display 80.The transmitting transducer converts the electrical signal sent by the controller through the touch screen cable into sound wave energy and transmits it to the left surface, and then a set of precision reflection stripes under the glass plate reflects the sound wave energy into an upward uniform surface for transmission. The surface of the screen body is formed by the reflection stripes on the top to form a rightward line that is transmitted to the X- axis receiving transducer. The receiving transducer converts the returned surface acoustic wave energy into an electrical signal.
