Multi-Layer Voltage Line Layout for Simpler LED Display Fabrication

The patent applies dimensionality change by forming voltage lines at different vertical levels (first conductive layer and second conductive layer) rather than in a single plane. This allows multiple voltage lines to be integrated without requiring additional lateral space or separate manufacturing steps, thereby reducing process complexity while managing structural complexity through vertical arrangement.

The patent segments the conductive layer structure into multiple distinct layers (first conductive layer with first and second voltage lines, second conductive layer with third and fourth voltage lines). This segmentation allows each layer to be formed independently with specific voltage lines, simplifying the manufacturing process by enabling parallel formation of multiple voltage lines across different layers.

The patent merges the formation of multiple voltage lines into a unified multi-layer conductive structure. By combining first and second voltage lines in the first conductive layer and third and fourth voltage lines in the second conductive layer, the patent achieves manufacturing efficiency through integrated formation processes while maintaining ease of manufacture through systematic layer organization.

The patent uses vertical dimensionality to resolve the contradiction between manufacturing efficiency and ease of manufacture. By distributing voltage lines across multiple vertical layers, the patent enables efficient parallel manufacturing of multiple voltage lines while keeping each layer's formation process relatively simple and manageable.
