Problems solved by technology

[0004] However, since the light intensity emitted by the organic light-emitting unit in the screen itself has certain limitations, the thickness that the light emitted by the organic light-emitting unit can penetrate is generally small, so the requirement for the thickness of the screen is relatively high, and the optical fingerprint recognition The setting also affects the pixel distribution in the screen, which is not conducive to realizing the high resolution of the screen

Abstract

The invention provides a fingerprint recognition device and a fingerprint recognition panel, relates to a fingerprint recognition technology, and can solve the problem that the requirement of an existing optical fingerprint module for the thickness of a screen body is high. The touch screen comprises a pressure change layer, a sensing receiving layer and a fingerprint identification module, Wherein the pressure change layer is made of an elastic and conductive material; Wherein the sensing receiving layer and the pressure change layer are oppositely arranged, a pressure change gap is formed between the sensing receiving layer and the pressure change layer, and the pressure change gap is used for accommodating deformation of the pressure change layer towards the sensing receiving layer whenthe pressure change layer is pressed; Wherein the sensing receiving layer and the pressure change layer are electrically connected with the fingerprint identification module, and the fingerprint identification module is used for determining electric field distribution between the sensing receiving layer and the pressure change layer according to deformation of the pressure change layer when the pressure change layer is pressed.

Description

technical field [0001] The present invention relates to fingerprint identification technology, in particular to a fingerprint identification device and a fingerprint identification panel. Background technique [0002] At present, in order to protect the information security of users, the use of fingerprint recognition function on smart terminals such as mobile phones is becoming more and more common, for example, it is used for unlocking smart terminals and mobile payment. Great convenience. [0003] In the prior art, by arranging an optical fingerprint module on the back of the screen body of the smart terminal, that is, the surface facing away from the user, the light emitted by the organic light-emitting unit in the screen body is reflected by the different energies of the peaks and valleys of the fingerprint of the finger, and then is reflected by the screen. The optical fingerprint module on the back of the body receives, and through the energy difference between the p...
