Problems solved by technology

[0007] The purpose of the present invention is to provide a biometric image acquisition system, which aims to solve the problem that the existing biometric image acquisition technology needs the light emitted by the display panel as a signal source, so that the biometric image can only be obtained when the display panel is working. This makes the problem of limited application

Embodiment Construction

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely intended to illustrate the invention and are not intended to limit the invention.

[0023] A biomechanical image acquisition system of the embodiment of the present invention, by having a plurality of array sensor units on the substrate, each array sensor unit includes a first preset region and a second preset area, the first preset area The optical signals used to make the display panel are used to generate infrared light to the collected organism when the display panel is turned off, and the reflected signal is processed and generates a biometric image.

[0024] In order to illustrate the technical solution of the present invention, the following will...

Abstract

The invention belongs to the technical field of image acquisition, and provides a biometric image acquisition system. A plurality of array sensor units (210) are provided on a substrate (200), and each array sensor unit (210) includes a first preset An area (211) and a second preset area (212), the first preset area (211) is used to make the light signal emitted by the display panel penetrate, and the second preset area (212) is used when the display panel is closed When the infrared light is generated to the collected organism, the reflected signal is processed and the biometric image is generated, so it is not limited by the display content of the display panel light source, and the biometric image can be obtained even if the display panel is turned off. Therefore, the existing biometric image acquisition technology needs the light emitted by the display panel as a signal source, so that the biometric image can only be acquired when the display panel is working, which limits the application.

Description

Technical field [0001] The present invention belongs to the field of image acquisition, and in particular to a biometric image acquisition system. Background technique [0002] Since 2013 Apple mobile phone iPhone5s has introduced fingerprint recognition, fingerprint recognition technology is widely used in smart devices. Its simple and fast simultaneous feature, so that hundreds of millions of people receive and rely on fingerprint identification as mobile phones, tablets and other intelligence. The unlocking device of the device, while the mobile payment is raised, with the fingerprint recognition instead of the password to save the worry of the input password. Today, the fingerprint recognition module has become a smartphone standard configuration. [0003] The combination of fingerprint recognition and display technology is the problem of mobile phone developers for adapting to users of mobile phone screens and full-screen fingerprint recognition. If the optical fingerprint t...
