Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pixel sizes are decreased to increase display resolution, then display detail is improved, but luminescent efficiency is rapidly lowered
Solution Approach 1:
The electrode structures are segmented into multiple opening arrays with different patterns. The first electrode has a first opening array and the second electrode has a second opening array, creating segmented light transmission paths that reduce light loss and improve luminescent efficiency while maintaining high display resolution through the segmented micro-structure design
Solution Approach 2:
The patent introduces a vertical dimension by stacking multiple electrode layers with different opening patterns at different heights. This three-dimensional arrangement of opening arrays allows light to pass through multiple layers without complete overlap, improving both resolution and luminescent efficiency by utilizing spatial distribution in multiple dimensions
2Ease of manufacture
If conventional display technologies are used to maintain simple manufacturing, then manufacturing complexity is low, but luminescent efficiency remains very low
Solution Approach 1:
The support member serves multiple functions: it maintains the spacing between electrode layers, provides structural support, and enables the voltage-driven movement of the second electrode. This multi-functional design simplifies the overall structure while achieving improved luminescent efficiency through the movable electrode configuration
Solution Approach 2:
The second electrode is designed to be movable relative to the first electrode through voltage application. This dynamic configuration allows the device to switch between different states (electrode close together vs. electrode spaced apart), enabling control of light transmission and improving luminescent efficiency without requiring complex manufacturing
3Device complexity
If electrode opening arrays are overlapped to simplify structure, then device complexity is reduced, but light transmission control is insufficient
Solution Approach 1:
The first and second opening arrays are designed with asymmetric, non-overlapping patterns. The first opening array and second opening array have different spatial distributions, creating an asymmetric light transmission path that enhances control over light transmission while maintaining relatively simple electrode structures
