Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional conductive lines and connection lines are used in display apparatuses, then electrical connectivity is achieved, but resolution and light emission efficiency are limited due to design constraints
Solution Approach 1:
The conductive line is divided into multiple discrete conductive patterns spaced apart from each other, rather than using a continuous conductive line. This segmentation allows for reduced optical interference and improved resolution while maintaining electrical connectivity through the alternating connection patterns.
Solution Approach 2:
Connection patterns are introduced as intermediary elements that electrically connect the separated conductive patterns. These connection patterns act as mediators to maintain electrical continuity while allowing the conductive patterns to be spatially separated for improved resolution and light emission.
2Illumination intensity
If conventional connection lines are used, then electrical connections are established, but transmittance and brightness are reduced due to material and structural limitations
Solution Approach 1:
Different regions of the conductive system have different properties: conductive patterns provide electrical connectivity while connection patterns provide optical transparency. This local differentiation of function allows the connection lines to have high transmittance in critical areas while maintaining necessary electrical connections.
Solution Approach 2:
The conductive system uses composite structures combining different conductive materials with varying transmittance properties. This allows optimization of both electrical conductivity and optical transmittance in different parts of the system, improving overall brightness while maintaining connectivity.
3Measurement precision
If conductive patterns are placed closer together to improve resolution, then pixel density increases, but electrical interference and manufacturing difficulty increase
Solution Approach 1:
The alternating arrangement of conductive patterns and connection patterns creates a multi-dimensional structure that separates electrical pathways spatially. This dimensional organization reduces electrical interference between adjacent pixels while maintaining manufacturability through systematic patterning.
