Abstract

The invention relates to the technical field of fingerprint recognition, and particularly to a detection module, a display device and electronic equipment. The detection module of the invention is used to be disposed on an opposite side of one side which is of a display module and is used for display, and realizes at least one function in fingerprint recognition, pressure sensing and touch recognition. In a direction from a place near the display module to a place away from the display module, the detection module includes an upper electrode layer, a piezoelectric layer, a lower electrode layer, a non-conductive substrate and a circuit board which are sequentially disposed in a laminated manner. The circuit board is electrically connected with the upper electrode layer and the lower electrode layer respectively. The size of the detection module is equivalent to the size of the display module. The detection module, the display device and the electronic equipment of the invention have the advantages of simple structures and high reliability, and more accord with trends of lightening and thinning and high integration degrees of electronic equipment.

Description

【Technical field】 [0001] The invention relates to the technical field of fingerprint identification, in particular to a detection module, a display device 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 detection modules are ...
