Problems solved by technology

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. Unable to analyze fingerprint images; 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 devices are very complicated and the integration level is low.

Description

【Technical field】 [0001] The invention relates to the technical field of fingerprint identification, in particular to 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 display devices are very complicated and t...
