Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If LED chips are positioned close to substrate edges to maximize display area, then display area is improved, but tiling distance becomes insufficient
Solution Approach 1:
The patent segments the substrate into distinct functional zones: a display area containing pixel units and LED chips, and a non-display area (edge region) providing sufficient tiling distance. This segmentation allows the display area to be maximized while ensuring the edge region maintains adequate spacing for tiling operations, resolving the contradiction between display area and tiling distance.
2Length of moving object
If LED chips are positioned away from substrate edges to ensure sufficient tiling distance, then tiling distance is improved, but display area is reduced
Solution Approach 1:
The patent optimizes the two-dimensional layout by strategically positioning LED chips within pixel units that are themselves located within the display area, maintaining adequate distance from substrate edges. This dimensional optimization ensures sufficient tiling distance while maximizing the utilization of display area through efficient spatial arrangement.
3Device complexity
If multiple LED chips share a single pixel unit, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent merges multiple LED chips (first, second, and third LED chips) within a single pixel unit, reducing the overall number of pixel units required and simplifying the device structure. This merging approach decreases device complexity while the standardized chip arrangements and defined positioning relationships help manage manufacturing precision requirements.
