Abstract: A touch screen panel comprises an outer surface that defines a touch sensitive surface with a touch sensitive area. The outer surface comprises friction features distributed throughout at least a portion of the touch sensitive area according to one or more predetermined spacings. The friction features are configured to have predetermined friction characteristics that impart a desired tactile effect, e.g., a paper-like feel, to the touch sensitive surface when contacted by a user's finger or a stylus. Methods of forming a touch screen panel with predetermined friction features are also described.
