The face-to-ear bridge structure of the present invention can be electrically connected to an external 単% (not shown) by means of a suitable shielding layer (Fig.: not shown) and using a connection line (not shown) to provide a touch function. Therefore, the touch panel bridging structure of the present invention is characterized in that the insulating layer = the via hole structure has a fine planarization of the conductive layer, and the access is limited by the risk of poor climbing due to poor exposure of the insulating layer (10). In addition, it can pass through the invented bridge structure to solve the problem that the bridge is clearly visible due to the width of the insulation layer, so the through hole is not limited to the special figure 八上上者 only as a transfer (four) Dejia 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 [Simple description of the diagram] f A diagram of the _ control panel bridging structure of the present invention.
