Abstract

The invention provides an ultrasonic touch screen system. The system comprises a substrate used for propagating ultrasonic, at least one transducer located on the upper side or the lower side of the periphery of the substrate, reflection fringes and a controller; the same transducer is used for receiving and emitting the ultrasonic, wherein the ultrasonic propagated along the surface of the substrate is used for touch recognition and / or fingerprint recognition, and the ultrasonic of which the propagation direction is perpendicular to the substrate is used for fingerprint recognition; the reflection fringes are located on the upper side of the periphery of the substrate and used for changing the ultrasonic propagation direction; the controller is electrically connected with the transducersand used for driving the transducers to vibrate so as to generate the ultrasonic, the transducers convert the received ultrasonic into electric signals, and the controller is used for processing the electric 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...
