Abstract

A touch screen includes a triple layer anti-reflective coating (ARC). The touch screen can be an analog or a matrix resistive touch screen. The anti-reflective coating includes two high index layers and a low index layer. The exposed high index layer is conductive. The anti-reflective coating can be provided on one or both of a flex layer and a stable layer.
