The invention discloses a layout method for electrodes of a touch pad and an electrode structure of the touch pad. The layout method includes steps that a substrate is provided; a first conducting layer is formed on one side of the substrate and provided with more than two pattern blocks which are arranged adjacently, and the first conducting layer is transparent; an alignment film layer is formed on one side of the substrate; a second conducting layer is formed on one side of the substrate, and provided with more than two electric leads used for being connected with at least one of the pattern blocks; and a protecting layer is formed on the second conducting layer and used for protecting the second conducting layer. By the aid of the layout method, common process for electrodes can be reduced, particularly, a third conducting layer and another protecting layer do not need to be formed on the other side of the substrate, an electrostatic effect can be effectively prevented, and capacitance and flexibility are improved.
Description
technical field [0001] The invention relates to a method and structure for laying out electrodes of a touch panel, especially electrodes with bridging grooves, and achieves the method and structure with the same effect through the smallest process structure. Background technique [0002] In the known technology, in the process of touch panel, two electrodes with different axes are formed on the substrate, and an insulating layer is formed again on one of the electrodes in one axis, so as to provide the electrodes in the other axis to pass through the The metal wires provided on the insulating layer are electrically connected. However, traditionally, the metal wires disposed on the insulating layer may be damaged due to subsequent processes, making conduction impossible, thereby resulting in a decrease in the production yield of the touch panel. [0003] Therefore, in some technologies, the metal wires can be disposed in the bridging grooves by using bridged groove technolog...
