Patent number: 9733749Abstract: A manufacturing process for forming a touch structure utilizes a first anti-etching optical layer to define the electrodes pattern and utilizes a second anti-etching optical layer to define the traces pattern. The first anti-etching optical layer and the second anti-etching optical layer do not need to be removed. The refractive index of the first anti-etching optical layer and the refractive index of the second anti-etching optical layer can be adjusted to reduce the display difference between the etched region and the non-etched region.Type: GrantFiled: December 18, 2013Date of Patent: August 15, 2017Assignee: TPK Touch Solutions Inc.Inventors: Chen-Yu Liu, Lu-Hsing Lee
