Graphene is a two-dimensional nanomaterial formed by the hybridization of carbon atoms. Graphene has become a popular new material in emerging industries because of its high conductivity, high toughness, high strength, high transparency, large specific surface area and other excellent properties. In view of the excellent properties and potential application value of graphene materials, a series of important progress has been made in semiconductor devices, transparent displays, sensors, capacitors, and other aspects. Graphene film light transmittance and conductivity is close to it ITO material, and can well solve the bottleneck of touch screen transparent electrode technology. It is one of the materials that replace Indium Tin Oxide (ITO) in flexible displays. Therefore, systematic research on graphene will play an important role in promoting the development of science and technology in the future. In this paper, the structure, properties, and development status of graphene are analyzed. Three traditional methods for preparing graphene films: mechanical peeling, chemical peeling, and chemical vapor deposition, and three novel process preparation methods: rotary spraying method, Plasma Enhanced Chemical Vapor Deposition (PECVD) method and layered self-assembly method are introduced. It summarizes the production process of graphene touch screen: transfer, modification, graphical, capacitive screen module preparation, its latest progress, and existing problems. Although preliminary studies have been conducted on the application of graphene films in various fields, the feasibility of its application has been verified, and it is expected to have significant advantages in some application fields, most of them are in the early stage of research and still face many technical challenges.
