Abstract
Electrostatic charge grounding is achieved by connecting an outer surface touchscreen conductive coating to a grounded conductor in a graphics terminal using an electrostatic charge routing system that provides a path for electrons that accumulate on the conductive coating to pass through one or more non-conductive elements in the graphics terminal. The grounded conductor can be a bezel made of metal or another conductor, a conductive paint layer applied to a bezel or other graphics terminal element, a metal spline pin or a metal screw. The electron path defined by the electrostatic charge routing system can include conductive and dissipative elements such as metal spline pins, metal screws, conductive epoxy, conducting plastic elements providing a short, closed electron bridge.
