Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is used in high temperature and high humidity environment, then the display device can operate in various conditions, but the metal components of the panel corrode due to electrolyte contamination
Solution Approach 1:
The patent introduces an anisotropic conductive film containing a corrosion inhibitor compound as an intermediary layer between the electrolyte environment and the metal components of the display panel. This mediator prevents direct contact between harmful electrolyte ions and the metal surface, thereby resolving the contradiction between environmental adaptability and corrosion resistance
Solution Approach 2:
The corrosion inhibitor compound creates a protective barrier that effectively isolates the metal components from the corrosive high temperature and high humidity environment, maintaining an inert protective atmosphere at the metal surface even when the display device operates in harsh external conditions
2Reliability
If a corrosion inhibitor compound is added to the anisotropic conductive film, then the corrosion resistance of the display panel is improved, but the complexity of the film composition increases
Solution Approach 1:
The patent optimizes the concentration parameter of the corrosion inhibitor compound within a specific range (0.1 to 10 wt%) to achieve effective corrosion protection while minimizing the impact on film composition complexity. This parameter optimization allows the system to gain corrosion resistance without excessive complexity
Solution Approach 2:
The patent creates a composite anisotropic conductive film by combining the corrosion inhibitor compound with existing film components (binder resin, conductive particles, cationic polymerizable resin). This composite approach integrates the corrosion protection function into the existing film structure, adding minimal complexity while achieving reliable corrosion resistance
