touch screen display repair.Ultrasonic touch screens include surface acoustic wave touch screens and bulk acoustic wave touch screens. They both use electro - acoustic piezoelectric transducers as sensors. The piezoelectric crystals used by the receiving sensor and the transmitting sensor are not a model. The difference is that the transmitting transducer has high power and the receiving transducer is more sensitive. The piezoelectric transducer has a long life and stable operation, and normal operation can guarantee no problems for 10 years. After the touch screen is installed, the transducer is hidden, but care must be taken during transportation and installation. The exposed transducer crystal cannot be squeezed. The surface acoustic wave touch screen has two pairs of sensors, X and Y axes, and uses the surface acoustic waves on the screen surface to detect finger touch. It can be said that the working surface is a layer of invisible and unbreakable acoustic energy. Inquiries are currently the most popular touch screen products on the market.
