NOVELTY - A silver paste graphene composite conductive paste comprises 20-30 pts. wt. graphene and 70-80 pts. wt. silver paste. The mixing ratio of graphene and silver paste in the conductive paste is 1:3. USE - Silver paste graphene composite conductive paste of transparent display screen used in city brightening project, large screen display system, large square lighting, stage scenery, bar, high-grade singing hall, city landmark building, municipal building, airport, automobile 4S shop, hotel, bank and brand chain store. ADVANTAGE - The silver paste graphene composite conductive paste is provided as the connection welding point of the LED lamp on the transparent display screen and the metal wire on the conductive glass, so as to realize the electric connection between the display screen and conductive glass. The conductivity and radiating performance of the conductive paste are improved so as to satisfy the electric signal transmission requirement of the large transparent display screen. The radiating performance of the conductive paste is improved. The LED lamp working for a long time to generate a large amount of heat to affect the service life of the transparent display screen is avoided.
