Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is expanded to include corner regions, then the display area increases, but the structural integrity and image quality may deteriorate
Solution Approach 1:
The display panel is segmented into a main display area with first pixels and a corner display area with second pixels. This segmentation allows different pixel arrangements and configurations to be used in different regions, enabling the corner area to be expanded while maintaining appropriate structural integrity and image quality through region-specific design optimizations.
Solution Approach 2:
Different pixel configurations and arrangements are applied to different regions of the display panel. The main display area uses one configuration while the corner display area uses another, allowing each region to have optimized local quality appropriate for its specific functional requirements and structural constraints.
2Manufacturing precision
If pixel circuits are arranged in alternating configurations in corner regions, then image quality improves, but device complexity increases
Solution Approach 1:
The pixel circuits in the corner display area are divided into different groups with different arrangement configurations. By segmenting the corner region into multiple pixel circuit groups with alternating arrangements, the patent achieves improved image quality through diversified circuit layouts while managing complexity through systematic regional division.
Solution Approach 2:
Alternating pixel circuit configurations are employed in the corner display area, creating asymmetric arrangements that optimize image quality by reducing moire effects and improving display uniformity. This asymmetric design accepts increased complexity as a trade-off for superior imaging performance in the corner regions.
3Area of stationary object
If signal lines are extended to cover corner regions, then display coverage increases, but signal transmission complexity increases
Solution Approach 1:
The signal transmission system is segmented to provide dedicated signal lines for different display regions. Corner pixel circuits are configured to receive signals through optimized routing that extends display coverage to corner areas while managing transmission complexity through region-specific signal distribution architectures.
