A first electrical signal is generated by a light sensation circuit in that fingerprint identification circuit according to the detected optical signal reflected by the finger, potential information of the first electrical signal is stored in a holding circuit, and a second electrical signal for fingerprint identification is output by a scanning circuit according to the potential information of the first electrical signal stored in the holding circuit, so that the fingerprint identification device can complete the collection of the electrical signals output by all the fingerprint identification circuits set by the fingerprint identification device in the case that the residence time of the user's finger is short, thereby supporting the design of fingerprint identification circuits with larger area and higher density in the optical fingerprint identification device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fingerprint identification circuit, display panel and control method thereof","description":"A fingerprint identification circuit, a display panel, and a control method thereof.
