The Importance of Touch Screens
In recent years, with the popularization of high-end smart electronic products, the development of the touch screen industry has reached an explosive growth period from quantitative change to qualitative change. There has been increasingly numbers of diversified products utilizing touch screens. The industrial-scale demand presnts a booming touch screen market. Its rapid development has greatly widened its application fields.
Accelerate Research and Practice of Graphene in Touch Screens
The market's demand for large-size, flexible, bendable, high-definition, and non-breakable touch screens is becoming increasingly prominent. The conductive film material that can meet the above-mentioned performance of the touch screen needs to have three conditions of low resistance, good optical penetration, and flexibility. Compared with the rare and expensive indium tin oxide (ITO) that is currently commonly used for transparent electrodes in OLED displays, graphene can provide a thinner, more transparent, faster, and lower cost alternative, thereby avoiding the shortage of ITO. Based on the long-term development of the industry, graphene is the most potential substitute for ITO materials.

Alfa Chemistry has put efforts in promoting the industrialization of graphene film materials in the touch display field, and strive to rapidly internationalize the graphene industry. Alfa Chemistry is committed to the commercial application of graphene films, and has formed a variety of process routes and mass production equipment in major key links such as film preparation and transparent conductive electrode manufacturing. A series of technical obstacles in graphene touch screen modules have been resolved.
