Engineering Contradiction Analysis
1Productivity
If display devices are connected through wireless network using antenna pattern, then connectivity and communication efficiency are improved, but device complexity increases due to integration of antenna and contact electrodes
Solution Approach 1:
The antenna pattern and contact electrodes are integrated into the same layer structure, combining communication and electrical connection functions into a unified design. This merging reduces the number of separate components and simplifies the overall device architecture while maintaining wireless connectivity capabilities.
Solution Approach 2:
The antenna pattern serves multiple functions: it enables wireless communication for network connectivity and simultaneously provides structural integration with contact electrodes for electrical connections. This multi-functionality improves communication efficiency without requiring entirely separate systems for each function.
2Manufacturing precision
If light emitting element size is reduced to nanometer to micrometer scale, then display resolution and density are improved, but manufacturing precision requirements increase
Solution Approach 1:
The light emitting element dimensions are optimized to specific nanometer to micrometer ranges, changing the size parameter to achieve high display density while maintaining manufacturability through controlled fabrication processes. This parameter optimization balances resolution improvement with manufacturing feasibility.
3Ease of operation
If wireless power transfer antenna is integrated into display device, then power supply convenience is improved, but energy loss may increase due to wireless transmission
Solution Approach 1:
The wireless power transfer antenna acts as an intermediary component that enables contactless power delivery to the display device. This intermediary facilitates convenient power supply operation while managing energy transmission losses through optimized antenna design and frequency selection.
