Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal materials are used in signal lines to ensure electrical conductivity and signal transmission, then electrical functionality is maintained, but optical transmittance in the first area deteriorates due to interference with camera modules and image quality
Solution Approach 1:
The data line is divided into different patterns with different materials based on location: first patterns in the first area use transparent conductive oxide for high transmittance, while second patterns in the second area use metal materials for reliable conductivity. This local differentiation resolves the contradiction by optimizing material selection for each specific area's requirements.
Solution Approach 2:
The data line structure combines multiple materials (transparent conductive oxide and metal materials) in different patterns and layers. This composite approach allows the system to achieve both high optical transmittance where needed (first area) and reliable electrical functionality where needed (second area), resolving the contradiction between these two requirements.
2Ease of manufacture
If a uniform data line structure is used across the entire active area to simplify manufacturing, then manufacturing complexity is reduced, but optical transmittance in the first area deteriorates due to unnecessary metal material presence
Solution Approach 1:
Instead of a uniform structure, the data line employs local quality differentiation with first patterns and second patterns using different materials in different areas. This resolves the contradiction by making the structure non-uniform only where necessary to achieve high transmittance in the first area while maintaining manufacturing feasibility through systematic patterning.
3Illumination intensity
If transparent conductive oxide is used in the first area to improve optical transmittance, then image quality and camera module performance are enhanced, but electrical conductivity compared to metal materials deteriorates
Solution Approach 1:
The invention applies transparent conductive oxide specifically in the first area where high optical transmittance is critical, while using metal materials in the second area where high conductivity is prioritized. This local differentiation resolves the contradiction by matching material properties to functional requirements in each area.
Solution Approach 2:
The data line structure combines transparent conductive oxide and metal materials in a composite configuration with first patterns and second patterns. This composite material approach allows the system to achieve optimal electrical conductivity and optical transmittance by selecting the appropriate material for each specific functional requirement.
