Engineering Contradiction Analysis
1Manufacturing precision
If plasma etching process is used in manufacturing, then high-resolution display apparatus can be manufactured, but static electricity may unintentionally damage components or degrade performance
Solution Approach 1:
The patent applies preliminary anti-action by introducing a ground line connected to a ground pad before the plasma etching process occurs. This ground connection is established in advance to prevent static electricity accumulation that would otherwise damage components during the plasma etching process. The ground line acts as a preventive measure against the harmful static electricity effects that inherently occur during high-resolution manufacturing.
2Ease of manufacture
If conventional conductive line structure is used, then manufacturing is simpler, but static electricity damage and charge accumulation occur
Solution Approach 1:
The patent segments the conductive line structure into functionally distinct components: signal transmission lines for normal operation and a separate ground line connected to a ground pad for static electricity dissipation. This segmentation allows the structure to simultaneously maintain manufacturing simplicity while providing dedicated pathways for charge management, thereby reducing static electricity damage without significantly complicating the overall manufacturing process.
