AI Technical Summary

Technical Problem

The limited functionality of existing biometric detection modules in electronic devices results in a lack of high integration and a sleek design, increasing the learning and measurement costs for users.

Method used

The texture recognition module is integrated with the bioelectric signal acquisition module. By setting a first conductive layer with a resistivity of 1×10-2Ω·m to 1×106Ω·m, it can have both identity recognition and bioelectric signal acquisition functions. An operational amplifier and a pre-detection module are combined to optimize the signal detection effect.

Benefits of technology

It achieves a two-in-one fusion of identity recognition and bioelectrical signal detection, improving the integration and sleek appearance of electronic devices, reducing the risk of unlocking with fake fingers, and reducing power consumption.

Abstract

The embodiment of the invention provides a detection assembly, a touch display screen, electronic equipment and a control method of the electronic equipment, relates to the field of electronics, and aims to provide the detection assembly which integrates a bioelectricity signal detection function and an identity recognition signal detection function. The detection assembly comprises a line recognition module, a first conductive layer and a bio-electricity signal acquisition module. The first conductive layer is arranged on the collection side of the line recognition module and serves as a biological sampling electrode. The line recognition module and the first conductive layer serving as a biological sampling electrode are fused with each other, so that one detection assembly has the functions of identity recognition and bio-electricity signal collection. Therefore, a user can obtain an identity recognition signal and a bio-electricity signal by placing a hand to-be-detected part on the detection assembly.
