Abstract

The invention provides a pressure induction module integrating a fingerprint recognition function, a driving method and a display device. The pressure induction module integrating the fingerprint recognition function comprises a pressure induction unit and a control unit, wherein the pressure induction unit comprises N rows and M columns of pressure induction subunits, pressure induction processing subunits and fingerprint recognition processing subunits, wherein N and M are both positive integers; the pressure induction subunit in the n(th) row and the m(th) column comprises a pressure induction module in the n(th) row and the m(th) column and a fingerprint recognition module in the n(th) row and the m(th) column, and the pressure induction processing subunits and the fingerprint recognition module in the n(th) row and the m(th) column are connected with the control unit, wherein n is a positive integer smaller than or equal to N, and m is a positive integer smaller than or equal to M; and the control unit is used for sending a fingerprint recognition control signal to the fingerprint recognition module in the n(th) row and the m(th) column after receiving a pressure induction instruction signal. Through the pressure induction module, the problems that in the prior art, the fingerprint recognition module is possibly triggered by mistake, consequently, power consumption is high, and unnecessary noise is caused by circuit coupling factors are solved.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a pressure sensing module integrated with a fingerprint identification function, a driving method thereof, and a display device. Background technique [0002] In the prior art, there have been many solutions for integrating optical fingerprint recognition into display devices. If the fingerprint recognition module is integrated into the full-screen display, the fingerprint recognition module may be triggered by mistake. For example, when the screen is normally on, the fingerprint The identification module is still working, which will increase power consumption, and may cause unnecessary noise due to circuit coupling factors, thereby affecting the display. Contents of the invention [0003] The main purpose of the present invention is to provide a pressure sensing module with integrated fingerprint identification function, its driving method and display device, which can solve th...
