Problems solved by technology

Among them, the fingerprint identification module installed on the back of the mobile terminal makes it impossible for the user to directly determine the position of the fingerprint identification module with the naked eye when viewing the mobile phone, which affects the user experience and reduces the aesthetic feeling of the back of the mobile terminal; and the integration of the fingerprint identification module The solution to the side of the mobile device, because the design of the mobile terminal is getting thinner and thinner, there is not enough space to install a sensitive and accurate fingerprint recognition module on the side of the mobile terminal, and it is gradually abandoned by the manufacturer
Moreover, the openings required to expose the fingerprint recognition module to the surface of the mobile terminal also cause certain static interference to the mobile terminal

Abstract

The present disclosure relates to an under-screen fingerprint verification device, method, storage medium and mobile terminal. The device includes: a pressure-sensitive fingerprint sensing module and a processing unit arranged at a preset distance below the screen of the mobile terminal; the pressure-sensitive fingerprint sensing The module is configured to collect the vertical deformation at each pixel in the contact area between the finger and the screen, and the two-dimensional coordinates of each pixel on the screen when a pressing action applied to a designated area of ​​the screen is detected, and the pressing pressure on the contact area between the finger and the screen; the processing unit is configured to compare the collected data with the pre-stored security fingerprint sample data, so as to realize fingerprint verification. The pressure-sensitive fingerprint sensing module integrated under the screen can collect the texture information and pressure information of the finger touching the screen to complete fingerprint verification, ensuring the sensitivity and accuracy of fingerprint recognition under the screen, and avoiding the fingerprint recognition module being installed on the mobile terminal While on the back, the screen-to-body ratio is increased.

Description

technical field [0001] The present disclosure relates to the technical field of fingerprint verification, and in particular to an off-screen fingerprint verification device, method, storage medium and mobile terminal. Background technique [0002] With the development of mobile terminals, a full screen has gradually become a trend in the design of the front surface of the mobile terminal. When designing a full-screen mobile terminal, the front camera and fingerprint recognition device, which are usually installed on the front surface of the mobile terminal, have always been a major problem for various manufacturers to increase the screen-to-body ratio of the front surface of the mobile terminal. In related technologies, for the fingerprint sensor, some manufacturers choose to integrate the fingerprint identification module into the back or side of the mobile device. Among them, the fingerprint identification module installed on the back of the mobile terminal makes it impos...
