Description

Touch structure

The present invention is a touch structure that provides a touch structure for improving or reducing electrode pattern traces or etch marks.

The etched region has no conductive film ITO, and the light can be directly incident on the transparent substrate. Since the refractive indices of the two regions are different from each other, the user can observe the etching line where the ITO region and the etching region are overlapped, and the display screen often has faults, blurred images, granulated particles, or reduced resolution. The picture quality is not good.
