Abstract

A touch panel includes a substrate, a plurality of first and second conductive series, and a plurality of first and second auxiliary electrodes. The first and the second conductive series are disposed alternately on the substrate and located on a light-transmission area of the substrate. A portion of each of the first and second conductive series extends to a peripheral area of the substrate. The first and the second auxiliary electrodes are disposed on the peripheral area. The first auxiliary electrodes connect to the portion of the first conductive series extending to the peripheral area and generate capacitive sensing with the portion of the second conductive series located on the peripheral area. The second auxiliary electrodes connect to the portion of the second conductive series extending to the peripheral area and generate capacitive sensing with the portion of the first conductive series located on the peripheral area.
