OLED Array Substrate Parallel Power Lines Voltage Drop

The patent applies composite materials by creating a hybrid power line structure where aluminum power lines (providing manufacturing stability) are combined with copper or silver auxiliary power lines (providing low resistivity). These two different materials work together in the same circuit to simultaneously achieve manufacturing reliability and reduced voltage drop, directly resolving the technical contradiction between stability and energy loss.

The patent applies local quality by assigning different functional roles to different parts of the power line system. Copper or silver auxiliary power lines are used specifically in segments where low resistivity is critical for reducing voltage drop, while aluminum power lines are used in segments where manufacturing stability is paramount. This localized application of different material properties resolves the contradiction between reducing energy loss and maintaining process stability.

The patent applies merging by integrating the aluminum power line and copper/silver auxiliary power line into a unified parallel connection structure. The two different material lines are combined in parallel within the same circuit architecture, allowing them to work together synergistically to reduce voltage drop while sharing the same manufacturing and design framework, thus managing the complexity through unified integration rather than separate systems.
