US 2010/0164881 A1 · Touch Panel Structure

Abstract

A touch panel structure is provided. The touch panel structure comprises a cover glass, a first transparent electrode and a light shielding element. The cover glass has a touch surface, a sensing surface corresponding to the touch surface, wherein the sensing surface is defined with a center area and a peripheral area surrounding the center area thereon. The first transparent electrode is formed on the cover glass, comes into contact with the sensing surface and is disposed in the center area correspondingly. The light shielding element is formed on the cover glass, comes into contact with the sensing surface and is disposed in the peripheral area correspondingly.
