The method includes steps of mixing and heat-treating a first polymer, a second polymer, and a third polymer to obtain a first mixture, adding a light-transmitting material to the first mixture to obtain a second mixture, adding a nano material to the second mixture to obtain a third mixture, performing subsequent processing on the uniformly mixed third mixture to obtain the polymer composite material. The polymer composite material is configured to replace conventional protective glass in ultrasonic fingerprint recognition technology, and to improve accuracy of fingerprint recognition."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for preparing polymer composite material and display panel for fingerprint recognition","description":"A method for preparing a polymer composite material is provided.
