Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single scan driving circuit is used for both main display area and component area, then device complexity is reduced, but brightness uniformity and image quality deteriorate due to load deviations
Solution Approach 1:
The scan driving circuit is segmented into a first scan driving circuit for the main display area and a second scan driving circuit for the component area. This segmentation allows independent optimization of driving parameters for each region, eliminating brightness uniformity issues caused by mixed loading while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
Different scan driving circuits are assigned to different regions (main display area vs. component area) based on their specific requirements. The first scan driving circuit is optimized for high-resolution display needs, while the second is optimized for component area requirements, ensuring each region receives appropriate driving characteristics for optimal image quality.
2Adaptability or versatility
If electronic components are integrated in the component area, then device functionality is enhanced, but light transmission and image quality deteriorate
Solution Approach 1:
The display area is segmented into a main display area and a component area, allowing electronic components to be integrated in the component area without compromising the optical performance of the main display area. This spatial segmentation enables enhanced device functionality while preserving light transmission quality in the primary display region.
3Illumination intensity
If separate scan driving circuits are used for main and component areas, then image quality and brightness uniformity are improved, but device complexity increases
Solution Approach 1:
The scan driving circuit is divided into two independent circuits, each optimized for its specific region. This segmentation improves brightness uniformity by eliminating cross-interference between different loading conditions, while the modular design keeps device complexity manageable through clear functional separation.
Solution Approach 2:
Each scan driving circuit is designed with local quality in mind, with the first circuit optimized for main display area requirements and the second for component area requirements. This localized optimization achieves superior image quality and brightness uniformity without requiring overly complex integrated solutions.
