Abstract

The invention relates to the technical field of fingerprint identification, in particular to a display module and an electronic device. The display module includes an identification module, an ultrasonic wave transmitting module and a display module. A side of the display module for displaying is a display side. The identification module and the ultrasonic wave transmitting module are respectivelylocated on two opposite sides of the display module, and one of the identification module and the ultrasonic wave transmitting modules is located on the display side of the display module. The identification module includes a first electrode layer, a first piezoelectric layer and a second electrode layer. The first electrode layer and the second electrode layer are respectively disposed on two opposite surfaces of the first piezoelectric layer, and at least one of the first electrode layer and the second electrode layer is electrode blocks arrayed on the surface of the first piezoelectric layer. The first electrode layer of the identification module is fixed on the display side of the display module. The electronic device uses the above display module. The display module and the electronic device have the advantages of simple structure.

Description

【Technical field】 [0001] The invention relates to the technical field of fingerprint identification, in particular to a display module and an electronic device. 【Background technique】 [0002] At present, fingerprint recognition technology has been widely used in mobile terminals, smart homes, crime fighting and other fields. It brings a lot of convenience and safety to people's lives. At present, the mainstream fingerprint recognition technologies include optical fingerprint recognition, capacitive fingerprint recognition and ultrasonic fingerprint recognition, but they also have their own shortcomings, such as optical fingerprint recognition and capacitive fingerprint recognition, when the finger has oil, dust, water and other substances. The fingerprint image cannot be parsed; and ultrasonic fingerprint recognition has less requirements for the application environment, so ultrasonic fingerprint recognition is widely used. [0003] However, the structures of the existing...
