A first stage of amplifying unit is configured to receive a fingerprint voltage, perform a voltage amplifying process on the fingerprint voltage, and output the fingerprint voltage on which the voltage amplifying process has been performed. A second stage of amplifying unit is configured to receive the fingerprint voltage on which the voltage amplifying process has been performed, perform a current and power amplifying process on the fingerprint voltage on which the voltage amplifying process has been performed, and output the fingerprint voltage on which the current and power amplifying process has been performed. A voltage difference between a valley and a ridge of a fingerprint is amplified, so that the signal can be read out easily and correctly and the output ability of the signal is enhanced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fingerprint driving circuit and display panel","description":"A fingerprint driving circuit and a display panel are provided.
