Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transmissive areas are added to allow light transmission for additional functions (camera, sensor), then the functionality and light transmission capability are improved, but the display area and image quality are reduced
Solution Approach 1:
The display panel is divided into multiple display areas (first display area and second display area) with distinct functions. The second display area contains sub-pixel circuit areas surrounded by transmissive areas, allowing different regions to serve different purposes (display vs. light transmission) simultaneously, thus resolving the contradiction between functionality and display area.
Solution Approach 2:
Different regions of the display panel are assigned different properties: the first display area maintains full display functionality, while the second display area has localized transmissive regions surrounding sub-pixel circuits. This local differentiation allows light transmission in specific areas without compromising the overall display area and image quality.
2Adaptability or versatility
If transmissive areas are created for component arrangement, then component integration is improved, but image quality uniformity deteriorates
Solution Approach 1:
The transmissive areas are strategically positioned only in the second display area surrounding sub-pixel circuit areas, while the first display area maintains uniform display properties. This localized approach allows component integration in specific regions without affecting image quality uniformity across the entire panel.
Solution Approach 2:
The display panel is segmented into first and second display areas with different functional characteristics. The second display area is further segmented into sub-pixel circuit areas and transmissive areas, allowing precise control over where components are integrated and where light transmission occurs, thereby maintaining overall image quality uniformity.
3Reliability
If signal lines use metallic materials for electrical connection, then electrical conductivity is improved, but light transmission capability is reduced
Solution Approach 1:
The signal line is constructed as a composite structure combining transparent conductive material and metallic material. The transparent conductive material portion allows light transmission while providing electrical conductivity, and the metallic material portion enhances electrical connection reliability. This composite approach resolves the contradiction between electrical conductivity and light transmission capability.
Solution Approach 2:
Different portions of the signal line have different material compositions optimized for their specific functions: transparent conductive material in regions requiring light transmission and metallic material in regions requiring enhanced electrical connection. This local material differentiation resolves the contradiction between electrical reliability and light transmission.
