Touch panel

摘要

A touch panel includes a transparent substrate, electrodes, traces and at least two ground rings on the transparent substrate. The traces connect the electrodes to transmit signals. At least two ground rings connect to each other through a plurality of bridges and surround the electrodes and the traces. Each bridge has at least one ESD tip or peak to enhance local electric field strength and electrostatic discharge.

1. A touch panel, comprising:
a transparent substrate; a plurality of electrodes and traces on the transparent substrate, the traces connecting the electrodes to transmit signals; and a first ground ring and a second ground ring on the transparent substrate and surrounding the electrodes and the traces, a plurality of bridges connecting the first and the second ground rings, the bridge comprising at least one electrostatic discharge tip to enhance a local electric field strength and to initiate electrostatic discharging, wherein the first ground ring and the second ground ring are separated by a space of atmosphere so that the bridges across the space of atmosphere initiate electrostatic discharging toward atmosphere environment.
