Patent ID: 8420970

Claim:
A touch panel, comprising: a substrate; a plurality of first bridges, disposed on the substrate; an insulating layer, disposed on the substrate and covering the first bridges; a plurality of conductive columns, disposed in the insulating layer, wherein each of the first bridges is connected to two adjacent conductive columns; a plurality of second bridges, disposed on the insulating layer and crossing the first bridges respectively; a plurality of first sensing pads, disposed on the insulating layer and connected to the conductive columns, wherein each of the first bridges is located between two adjacent first sensing pads; a plurality of second sensing pads, disposed on the insulating layer, wherein each of the second bridges is connected between two adjacent second sensing pads; a reticulated electrode, disposed on the insulating layer and having a plurality of openings arranged in an array, wherein the first sensing pads and the second sensing pads are located in the openings respectively, and the first sensing pads and the second sensing pads are electrically insulated from the reticulated electrode; and a plurality of discharge electrodes, disposed on the insulating layer and connected to the reticulated electrode, wherein each of the discharge electrodes is located between two adjacent first sensing pads and between two adjacent second sensing pads.
