Abstract
Since two dimensional material of single atomic carbon layer – graphene was isolated successfully from HOPG using mechanical exfoliation methods in 2004, many researchers have showed their interests to the graphene’s fantastic and excellent properties. In addition to physical properties of the graphene, the graphene also attracts more interests in touch technology due to its high transmittance, stiffness and conductivity properties. Transparent conductive film is a kind of substance which can be combined with the grapheme quickly in touch industry. In the past, the communication interface between men and computers is keyboard or mouse; however, touch technology enables users to perform fast, intuitive function selection today and brings new experiences to users. Nowadays touch technology is becoming increasingly popular and no one can live without it. So how to use the graphene in this field becomes an important issue. In this study, we changed the metal bridge structure, the traditional process of making touch panels, and use bottom bridge structure to make the graphene touch panel. Finally, we developed the graphene touch panel manufacturing process successfully, and achieved a multi-point sensing graphene capacitive touch panel inclusive of two structures — bottom bridge structure and double side structure. It can be the foundation of flexible touch panel practical applications and provides diverse development of indicators to followers in the display industry in the future.
