US 2013/0092520 A1 · TOUCH DEVICE AND FABRICATION METHOD THEREOF

Abstract

The present disclosure relates to a touch technology, and more particularly to a touch device and a fabrication method thereof. The touch device comprises a sensing area and a peripheral area. The touch device further comprises a sensing electrode layer, a shading layer, a signal transmission line layer, and a conductive layer. The sensing electrode layer extends from the sensing area to the peripheral area. The shading layer is disposed on the peripheral area to overlay the sensing electrode layer and has a through hole to expose a portion of the sensing electrode layer. The signal transmission line layer is disposed on the shading layer and does not cover the through hole. The conductive layer fills the through hole and electrically connects the sensing electrode layer. In addition, a fabrication method of a touch device is also provided.

Dependent claims

A touch device, comprising a sensing area and a peripheral area surrounding the sensing area, further comprising:

a sensing electrode layer extending from the sensing area to the peripheral area;
a first shading layer disposed on the peripheral area and overlaying the sensing electrode layer disposed on the peripheral area, wherein the first shading layer has a through hole to expose a part of the sensing electrode layer disposed on the peripheral area;
a signal transmission line layer disposed on the first shading layer without covering the through hole;
and
a conductive layer filled in the though hole of the first shading layer until conductive material overflows, wherein the conductive layer is electrically connected to the sensing electrode layer and the signal transmission line layer.
