Terminal equipment and full-screen fingerprint recognition method

The invention discloses terminal equipment and a full-screen fingerprint recognition method, which are used for realizing fingerprint recognition at any position of a screen. The terminal equipment comprises a screen, a plurality of ultrasonic transducers and a processor, the ultrasonic transducers are respectively coupled to the edge of the lower surface of a cover plate of the screen, and the ultrasonic transducers are also respectively coupled to the processor. The ultrasonic transducer is used for generating a first surface acoustic wave under the control of the processor; and under the control of a processor, a second surface wave is received, an electric signal corresponding to the second surface acoustic wave is output to the processor, and the second surface acoustic wave is generated after the first surface acoustic wave is propagated from the lower surface of the cover plate to the upper surface of the cover plate and then scattered by a finger pressed on the upper surface ofthe cover plate of the s
