Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If alignment electrodes are used to align light emitting elements, then alignment efficiency is improved, but device complexity increases due to additional electrodes and signal phases
Solution Approach 1:
The alignment electrode structure is segmented into multiple independent electrodes (first alignment electrode, second alignment electrode, first auxiliary electrode, second auxiliary electrode) that can be controlled separately. This segmentation allows independent control of different electrode groups, enabling complex alignment patterns while maintaining manufacturing precision.
Solution Approach 2:
The system employs dynamic signal control with multiple phases applied to different electrodes. By dynamically switching signal phases (0-degree phase and 180-degree phase) across different electrodes, the system achieves precise and flexible alignment control without requiring static complex structures.
2Manufacturing precision
If auxiliary electrodes with different signal phases are added, then deflection alignment efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The auxiliary electrodes are segmented as separate components from the main alignment electrodes, allowing independent fabrication and positioning. This segmentation enables precise control over electrode spacing and positioning, which is critical for achieving the desired deflection alignment efficiency.
Solution Approach 2:
The system utilizes parameter changes in signal phase (0-degree and 180-degree phases) applied to different auxiliary electrodes to achieve deflection alignment. By changing the electrical parameters rather than physical structure, the system improves alignment efficiency while managing manufacturing complexity.
