In the fingerprint recognition device of the present disclosure, the collimator transmits the collimated light reflected by the fingerprint and blocks the scattered light, so that the light emitted by the light emitting layer is reflected by the finger, and the approximately collimated reflected light can transmit through the collimator while the oblique light is blocked by the collimator. The sensor recognizes the ridges and valleys of the fingerprint according to the area through which the light is transmitted by the collimator. The fingerprint recognition device may be manufactured by a simple manufacturing process and have strong practicability, and is suitable for fingerprint collection and recognition in the display area of the organic light emitting diode display."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fingerprint recognition device and manufacturing method thereof, display panel and manufacturing method thereof and fingerprint recognition method","description":"Provided are a fingerprint recognition device and a manufacturing method thereof, a display panel and a manufacturing method thereof, a display device, and a fingerprint recognition method.
