Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If auxiliary structures are added between adjacent first gate drive circuits, then electrical performance is improved and etching uniformity is ensured, but device complexity increases
Solution Approach 1:
The patent introduces auxiliary structures (including auxiliary semiconductor blocks and auxiliary electrodes) as intermediary elements between adjacent first gate drive circuits. These auxiliary structures serve as mediators to improve etching uniformity by providing reference surfaces and to enhance electrical performance by optimizing signal transmission paths, thereby resolving the contradiction between reliability improvement and device complexity increase.
Solution Approach 2:
The auxiliary structures are strategically positioned only in specific regions where adjacent first gate drive circuits are located, rather than uniformly across the entire display substrate. This localized approach ensures etching uniformity and electrical performance improvement in critical areas while minimizing the overall increase in device complexity.
2Manufacturing precision
If auxiliary structures are strategically placed between adjacent first gate drive circuits, then etching uniformity is ensured, but manufacturing complexity increases
Solution Approach 1:
The auxiliary structures function as intermediary reference surfaces that provide consistent geometric features for the etching process. By placing these auxiliary structures between adjacent first gate drive circuits, the patent creates uniform etching conditions across different regions, ensuring etching uniformity while the structured arrangement helps maintain manufacturing feasibility.
3Reliability
If auxiliary structures are added to optimize circuit arrangement, then display quality is improved, but device complexity increases
Solution Approach 1:
The auxiliary structures serve as intermediary elements that optimize the circuit pattern arrangement between adjacent first gate drive circuits. They provide structural references that improve signal integrity and reduce interference, thereby enhancing display quality while their systematic integration minimizes the impact on overall device complexity.
