A transparent conductive substrate structure used for a thermoforming process includes a transparent cover plate and a touch sensing layer structure. The transparent cover plate includes a toughening layer on one side thereof. The touch sensing layer structure arranged on one surface of the toughening layer, and includes a first transparent conductive layer, a dielectric layer, a barrier layer, a second transparent conductive layer, and a buffer protective layer. Each transparent conductive layer is directly applied to the transparent cover plate, so that the thickness between the transparent conductive layers is below 1 &#x3bc;m. The thickness between layers may be reduced to increase the sensitivity of the touch sensing layer structure. To prevent each transparent conductive layer and an electrode wire layer from breaking during the thermoforming process, the transparent conductive substrate structure is combined with the buffer protective layer to strengthen the structure of each transparent conductive layer.

Transparent conductive substrate structure used for thermoforming process

A laser etching method for a transparent conductive plate includes the steps as follows: providing a transparent conductive plate having a transparent conductive layer; continuingly emitting a plurality of laser beams to the transparent conductive layer, and controlling the center points of the laser beams to move in a front path and a rear path partially overlapping a beginning portion of the front path for forming an end connection groove connecting the beginning and the end thereof, or controlling the center points of the laser beams to move in a transverse path and a longitudinal path without overlapping the transverse path for forming a T-shaped groove, or controlling the center points of the laser beams to sequentially move in a first path, a curve path, and a second path substantially perpendicular to the first path for forming a curve groove.
