Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional sealing materials are used to bond display substrates, then sealing integrity is achieved, but electromagnetic radiation pollution is generated affecting human health
Solution Approach 1:
The sealing material uses a composite formulation combining polyimide resin with specific inorganic fillers (silicon dioxide, titanium dioxide, zirconium dioxide, or aluminum oxide) dispersed throughout the matrix. This composite structure enables the material to maintain sealing integrity while the inorganic particles provide electromagnetic radiation shielding properties, resolving the contradiction between sealing performance and radiation protection.
Solution Approach 2:
The inorganic filler particles act as intermediary substances within the sealing material that intercept and scatter electromagnetic radiation before it can penetrate to affect human tissue. These particles serve as a mediating barrier between the display device and the surrounding environment, allowing the sealing material to fulfill both its structural sealing function and its radiation mitigation function simultaneously.
2Object-affected harmful factors
If inorganic fillers are added to polyimide for electromagnetic shielding, then radiation protection improves, but material homogeneity decreases
Solution Approach 1:
The inorganic fillers are distributed throughout the polyimide matrix to create localized regions of electromagnetic shielding capability. Rather than requiring uniform composition throughout, the material achieves effective radiation protection through the strategic dispersion of shielding particles at specific locations within the sealing structure, accepting localized heterogeneity for the benefit of overall radiation protection.
Solution Approach 2:
The patent optimizes parameters including the type of inorganic filler selected, the particle size distribution, and the concentration of fillers within the polyimide matrix. By carefully controlling these parameters, the material achieves effective electromagnetic shielding while minimizing negative impacts on homogeneity and processing characteristics.
