Abstract

The present invention provides an ultrasonic touch screen system, which includes a substrate for propagating ultrasonic waves; at least one transducer located on the upper or lower side of the periphery of the substrate, and the same transducer is used for receiving and transmitting The ultrasonic wave, wherein the ultrasonic wave propagating along the surface of the substrate is used for touch recognition and/or fingerprint recognition, and the ultrasonic wave whose propagation direction is perpendicular to the substrate is used for fingerprint recognition; reflection stripes are located at the periphery of the substrate The upper side of the ultrasonic wave is used to change the propagation direction of the ultrasonic wave; the controller is electrically connected to the transducer and is used to drive the transducer to vibrate to generate the ultrasonic wave, and the transducer will receive all The ultrasonic waves are converted into electrical signals, and the controller is used to process the electrical signals.

Description

technical field [0001] The invention relates to the field of ultrasonic waves, in particular to an ultrasonic touch screen system. Background technique [0002] Ultrasonic touch technology is currently a widely used touch technology. With the change of the use environment, the touch system has gradually transformed from the previous professional application fields, such as industrial control, POS and other industries, to general applications. In this process, the safety of the touch system is becoming more and more important. [0003] The current ultrasonic touch screen system usually combines fingerprint biometric identification function to achieve better security. The existing ultrasonic touch screen realizes the touch identification function by using piezoelectric ceramic substrate as a transducer. The touch system does not implement the fingerprint biometric identification function. In the application that needs to realize the fingerprint biometric identification functi...
