The first metal layer 200 is disposed on the first substrate 100, and the first metal layer 200 is used to provide a signal channel for the display panel, so that the first substrate 100 may be a thin film transistor substrate, and signal traces on the display panel are distributed on the first substrate 100 to provide electrical signals and control signals for a display area on the display panel. The second metal layer 300 is disposed in contact with the first metal layer 200, and the metal activity of the first metal layer 200 is stronger than that of the second metal layer 200, so when the second metal layer 300 is disposed on the surface of the first metal layer 200 or between the first metal layer 200 and the first substrate 100, it is equivalent to plating a protective layer around the first metal layer 200 to prevent the first metal layer 200 from being oxidized, so as to protect the first metal layer 200, and meanwhile, when the second metal layer 300 is disposed between the first metal layer 200 and the first substrate 100, the second metal layer 300 enhances the adhesion of the first metal layer 200 on the first substrate 100.
The metal reactivity of the first metal layer 200 is stronger than the metal reactivity of the second metal layer 300, when the first metal layer 200 and the second metal layer 300 are exposed to the environment, the first metal layer 200, the second metal layer 300 and the moisture in the air form a galvanic reaction, the first metal layer 200 with strong metal activity will be used as the cathode of the reaction and will be more easily corroded, so the external power 400 is installed on the display panel, the positive electrode of the external power source 400 is connected to the first metal layer 200, the negative electrode of the external power source 400 is connected to the second metal layer 300, so that the first metal layer 200 becomes the positive electrode, the second metal layer 300 becomes the negative electrode, when the first metal layer 200 and the second metal layer 300 are exposed to the environment, the first metal layer 200 is not corroded by the oxidation reaction as the positive electrode of the reaction, the signal wiring of the display panel is protected, and the condition that bubbles are generated in the display area is avoided.

Similarly, the main structural material of the second metal layer 300 may also be determined according to actual situations, as long as the metal activity thereof is ensured to be weaker than that of the first metal layer 200, and in the embodiment of the present invention, the second metal layer 300 may be selected from molybdenum (Mo), titanium (Ti), niobium (Nb), chromium (Cr), or the like, in consideration of the cost, strength, metal activity, and the like.
