Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transmissive area is integrated within the display area, then functionality for light transmission (e.g., cameras or sensors) is improved, but the display area is reduced
Solution Approach 1:
The display area is segmented into a first display area and a second display area, with the transmissive area integrated within the second display area. This segmentation allows the display to maintain its overall functionality while creating a dedicated zone for light transmission, thus resolving the contradiction between maintaining display area and enabling transmissive functionality.
Solution Approach 2:
The second display area is designed to serve dual purposes: it functions as a display region while also containing the transmissive area that allows light transmission for cameras or sensors. This multi-functionality approach enables the same physical space to fulfill multiple roles, improving versatility without sacrificing display area.
2Manufacturing precision
If distinct sub-pixel circuits with separate signal lines are used for first and second display areas, then display quality is improved, but device complexity increases
Solution Approach 1:
Distinct sub-pixel circuits and signal lines are provided for the first display area and the second display area. This segmentation allows independent control and optimization of each display region, ensuring high display quality for both areas while managing complexity through modular design.
Solution Approach 2:
Different signal lines (first signal line and second signal line) are used to transfer different signals to the sub-pixel circuits in different display areas. This local differentiation allows each area to be optimized for its specific function, with the second display area's signal lines configured to accommodate the transmissive area requirements.
3Ease of manufacture
If the second display area is surrounded by the first display area, then layout optimization is improved, but manufacturing complexity increases
Solution Approach 1:
The display area is divided into a first display area and a second display area arranged in an island configuration, where the second display area is surrounded by the first display area. This segmentation creates a clear layout structure that simplifies manufacturing planning while enabling the transmissive area to be properly positioned within the second display area.
