Abstract:
1. A projective capacitive touch sensor structure, comprising: a substrate; a first transparent patterned electrode disposed on the substrate; two second transparent patterned electrodes disposed on the substrate and located at two sides of the first transparent patterned electrode; a bridging wire striding over the first transparent patterned electrode and electrically bridging the second transparent patterned electrodes located at the two sides of the first transparent patterned electrode to form a conducting wire; and a transparent dielectric pad disposed between the bridging wire and the first transparent patterned electrode, wherein a dielectric portion of the transparent dielectric pad located above the first transparent patterned electrode and the second transparent patterned electrodes comprises an upper surface, a lower surface, and an inclined side surface connecting the upper surface and the lower surface, an area of the upper surface is 70% to 95% of an area of the lower surface, and an included angle between the inclined side surface and the lower surface is an acute angle.
