The invention discloses an arrangement method and structure of a bridging electrode capable of shielding bright spots. The arrangement method comprises the following steps of: providing a substrate; forming a transparent conductive layer on the substrate, wherein the transparent conductive layer is provided with a plurality of pattern blocks which are adjacently arranged mutually; forming an alignment film layer on the substrate, wherein the alignment film layer is provided with a plurality of bridging grooves which are transversely spanned among the pattern blocks; forming a conductive layer on the substrate, wherein the conductive layer is provided with a plurality of electric conductors which are respectively correspondingly arranged on the bridging grooves; forming a conductive corresponding layer at one side of the conductive layer, wherein the conductive corresponding layer is used for shielding the electric conductors; and forming a protection layer on the substrate, wherein the protection layer is used for increasing optical transmittance and protecting the substrate, the transparent conductive layer, the alignment film layer and the conductive layer.
Description
technical field [0001] The present invention relates to a method and structure for bridging electrode layout, in particular to a method and structure for shielding bright spots by using a conductive corresponding layer on one side of the conductive layer to shield the bright spots generated by the conductive layer. Background technique [0002] In the prior art, in the process of capacitive touch panel, two electrodes with different axial directions are formed on the substrate, and an insulating layer is formed again on one of the electrodes in the axial direction to provide the other axial direction. The electrodes are electrically connected through the metal wires provided on the insulating layer. However, conventionally, the metal wires disposed on the insulating layer may be damaged in the subsequent process, so that the metal wires cannot be turned on, thereby resulting in a decrease in the manufacturing yield of the capacitive touch panel. [0003] Therefore, in some ...
