Abstract

The embodiment of the invention provides a full screen fingerprint acquisition method and a mobile terminal. The full screen fingerprint acquisition method and the mobile terminal are characterized in that an ultrasonic transducer array is arranged below a touch screen of the mobile terminal; and the ultrasonic transducer array includes N independent fingerprint acquisition areas, and N is an integer and is greater than 1. The full screen fingerprint acquisition method includes the steps: when the touch screen senses a contact substance, obtaining a press area, of the touch screen, pressed by the contact substance; determining M independent fingerprint acquisition areas corresponding to the press area, in the N independent fingerprint acquisition areas, wherein M is a positive integer and is smaller than N; and using the ultrasonic transducer array corresponding to the M independent fingerprint acquisition areas to acquire the images of the contact substance. The full screen fingerprint acquisition method can activate the ultrasonic energy transducers of the corresponding areas to perform fingerprint acquisition during the process of ultrasonic full screen fingerprint identification, so as to reduce the power consumption of the mobile terminal.

Description

Technical field [0001] The invention relates to the field of data processing, in particular to a full-screen fingerprint collection method and a mobile terminal. Background technique [0002] In the prior art, mobile terminals (such as mobile phones, tablet computers, etc.) are mostly equipped with fingerprint recognition functions. The fingerprint recognition functions of most mobile terminals need to be implemented by pressing a specific area (such as home button, back button) of the mobile terminal. With the advent of full-screen fingerprint recognition technology, especially the ultrasonic-based full-screen fingerprint recognition technology, users can press any part of the touch screen of the mobile terminal to achieve fingerprint recognition operation, but at the same time it also increases the power consumption of fingerprint recognition. The problem. Summary of the invention [0003] The embodiment of the present invention provides a full-screen fingerprint collection met...
