Abstract

See full text

Alternating touchscreen conductors in each layer of a touchscreen display are connected to separate touchscreen controllers. Each controller completely and separately resolves a location anywhere on the display so that a failure of either controller, or the failure of conductors connected to either controller, do not degrade touchscreen usability. Conductors in separate layers, connected to separate controllers may be isolated via insulators to prevent undesirable shorts. Conductors are shaped to minimize the area covered by insulators and maximize the area of useful conductor overlap.
