  • Publication number: 20160103523
    Abstract: A touch device comprises a substrate, a plurality of sensing electrodes and a plurality of dummy electrodes. The sensing electrodes are disposed on the substrate. The dummy electrodes disposed on the substrate and between the sensing electrodes. The dummy electrodes are disposed separately by a plurality of trenches which are disposed across each other. An intersection of the trenches is configured with at least one first protrusion. Because of the first protrusion disposed at the intersection of the trenches, the corona discharge occurring at the dummy electrode can be reduced and the electrical performance of the touch device won't be deteriorated. Besides, the disposition of the first protrusion can blur the edge of the dummy electrode, so that human eyes will uneasily perceive the dummy electrode and the display performance of the touch device can be enhanced.
