ABSTRACT
Touchscreens are visual outputs that can detect the presence and location of a touch within the display area, permitting physical interaction with what is shown on the display itself. Touchscreen is an electronic visual display device that the user can control through simple or multi-touch gestures by touching the screen with a special stylus/pen and or one or more fingers. Touchscreens are easy to use and require no additional work space and no moving parts such as keyboard and mouse system. This chapter focuses on the aspects of graphene as a transparent electrode for touchscreen applications. Most resistive touch panels are designed to operate with a minimum threshold activation force. The chapter demonstrates the superior mechanical properties of a graphene film in the context of actual device performance. Graphene-based touchscreens are currently in production line and reaching end users.
