Engineering Contradiction Analysis
1Volume of moving object
If the size of light emitting devices is reduced to achieve miniaturization, then the display resolution and integration density are improved, but the arrangement and connection of terminals for leading wires become infeasible
Solution Approach 1:
The patent transitions from planar terminal arrangement to three-dimensional vertical stacking. Terminals are arranged in multiple layers (first terminal layer, second terminal layer) at different heights, with conductive holes penetrating through intermediate layers. This vertical dimensionality change allows terminals to be positioned without exceeding the light emitting device layer's coverage area while still providing adequate connection points for miniaturized devices.
Solution Approach 2:
The patent implements nested structures where conductive holes are formed within the light emitting device layer and extend to terminal layers. The terminal connection structure is nested within the overall display module, with terminals positioned within or at edges of the light emitting device layer coverage. This nesting allows compact integration of terminal connections within the miniaturized device footprint.
2Area of stationary object
If terminals are arranged within the coverage range of the light emitting device layer to maintain compact size, then the overall device footprint is reduced, but the electrical connection reliability may be compromised
Solution Approach 1:
The patent divides the terminal connection system into multiple independent terminal layers (first terminal layer, second terminal layer) with distinct functional roles. Each layer can be independently positioned and connected through conductive holes, providing redundant connection paths. This segmentation ensures that even if one connection path is compromised, alternative paths through different layers maintain electrical reliability.
Solution Approach 2:
By arranging terminals in multiple vertical layers rather than a single plane, the patent creates three-dimensional connection pathways through the light emitting device layer. Conductive holes penetrate vertically through the layer, establishing reliable electrical connections between terminals in different layers and the light emitting devices, thereby maintaining connection reliability within a compact footprint.
