Abstract

The invention relates to the technical field of fingerprint identification, and particularly relates to a display module and an electronic device. The display module comprises an identification moduleand a display module, wherein the identification module comprises a first electrode layer, a piezoelectric layer and a second electrode layer; the first electrode layer and the second electrode layerare arranged on two opposite surfaces of the piezoelectric layer respectively; at least one of the first electrode layer and the second electrode layer is electrode blocks arranged on the surface ofthe piezoelectric layer in an array mode; and the identification module is fixed on one side, for displaying, of the display module. The electronic device adopts the above display module. The displaymodule and the electronic device have the advantages of simple structures.

Description

【Technical field】 [0001] The invention relates to the technical field of fingerprint identification, in particular to a display module and electronic equipment. 【Background technique】 [0002] At present, fingerprint recognition technology has been widely used in many fields such as mobile terminals, smart homes, and crime fighting. It brings a lot of convenience and safety to people's life. The current 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. Fingerprint images cannot be resolved; and ultrasonic fingerprint recognition does not have such high requirements for the application environment, so ultrasonic fingerprint recognition is widely used. [0003] However, the structures of the existing display modules are all very complicated, ...
