touch screen display development kit.The three corners of the sound wave screen are respectively attached with transducers for transmitting and receiving sound waves in the X and Y directions (transducer: made of special ceramic materials, which are divided into transmitting transducers and receiving transducers. The electric signal sent by the device through the touch screen cable is converted into acoustic wave energy and surface acoustic wave energy gathered by the reflection stripes into electrical signals.), The four sides are engraved with reflection stripes reflecting the surface ultrasonic waves. When a finger or a soft object touches the screen, part of the sound wave energy is absorbed, so the received signal is changed, and the X and Y coordinates of the touch are obtained through the processing of the controller.
