Ultrasonic fingerprint identification region marking system with no need to carry out extra processing on mobile phone panel

Abstract

The invention provides an ultrasonic fingerprint identification region marking system with no need to carry out extra processing on a mobile phone panel. A fingerprint sensor can be hidden under the mobile phone panel without damaging the completeness of the panel. According to an existing scheme, in order to enable a user to find an ultrasonic fingerprint identification region, some extra processing is carried out on the mobile phone panel, for example, a sunken region is processed on the mobile phone panel, thereby enabling the user to identify. The invention provides the ultrasonic fingerprint identification region marking scheme with no need to carry out extra processing on the mobile phone panel. Through adoption of the scheme, a mobile phone display screen is an OLED screen; the whole screen stretches to the bottom of the mobile phone panel; through utilization of a micro power consumption feature when the OLED mobile phone screen displays black, the fingerprint identification region is marked by setting one part of the screen above a hidden fingerprint identification module to be constant bright; and the other part of the screen displays the black, thereby saving power; a user is guided through a mobile phone vibration unit, thereby informing the user of a fingerprint identification region range; and the completeness of the display panel does not need to be damaged for extra processing.

Description

technical field [0001] The invention relates to the field of information technology, the field of mobile phone hardware design and manufacture, and the field of fingerprint identification. In particular, it relates to an ultrasonic fingerprint identification area identification system that does not require additional processing on the panel of the mobile phone. Background technique [0002] Fingerprint identification refers to identification by comparing the detailed feature points of different fingerprints. Fingerprint recognition technology involves image processing, pattern recognition, computer vision, mathematical morphology, wavelet analysis and many other disciplines. Because everyone's fingerprints are different, even between the ten fingers of the same person, there are obvious differences in fingerprints, so fingerprints can be used for identification. With the development of smart phone technology, electronic chip technology and fingerprint recognition technol...

Problems solved by technology

It is more convenient and easy to use the iphone as the first to be placed under the front panel, but the problem that comes with it is that this placement method occupies the lower area of ​​the front panel of the mobile phone, making the display screen unable to expand to the entire front screen

The emergence of the ultrasonic fingerprint recognition scheme has provided a solution to this problem, that is, placing the ultrasonic module that can penetrate the display panel for fingerprint recognition under the panel, but how to identify the fingerprint recognition area hidden under the panel to the user becomes a problem. A new problem, the first Xiaomi 5s mobile phone that uses ultrasonic fingerprint recognition technology on the bottom of the front panel of the mobile phone chooses to polish a groove on the panel to remind users where the fingerprint identification is located, but this method destroys the front panel. Integrity, and cannot extend the display screen under the entire front panel
