Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple complicated manufacturing processes are performed to manufacture the display apparatus, then the display apparatus can be manufactured with multiple components, but defects or impurities are introduced leading to degraded picture quality and electrical characteristics
Solution Approach 1:
The side surface of the substrate is divided into multiple treatment areas (first treatment area, second treatment area, third treatment area) with different surface treatments. Each treatment area addresses specific manufacturing challenges locally, allowing complex manufacturing requirements to be met without compromising overall picture quality and electrical characteristics.
Solution Approach 2:
Different treatment areas on the substrate side surface have different surface properties (e.g., first treatment area with higher roughness for adhesion, second treatment area with lower roughness for insulation). This local differentiation allows each region to be optimized for its specific function, improving both manufacturing precision and device performance.
2Device complexity
If multiple complicated manufacturing processes are performed, then the display apparatus can be manufactured with multiple components, but the manufacturing efficiency is reduced
Solution Approach 1:
Multiple treatment areas with different surface treatments are integrated into a single substrate manufacturing process. This merging of multiple treatment functions into one unified approach improves manufacturing efficiency while maintaining the complexity of multiple components and their interconnections.
3Manufacturing precision
If the first treatment surface and second treatment surface are formed using different treatment methods, then the electrical characteristics and picture quality are improved, but the manufacturing process becomes more complex
Solution Approach 1:
Different treatment methods (e.g., laser treatment, chemical treatment, mechanical treatment) are applied to different treatment areas based on their specific functional requirements. The first treatment area uses one method for adhesion enhancement, while the second treatment area uses another method for insulation or electrical property optimization, thereby improving overall device performance.
Solution Approach 2:
The side surface is segmented into multiple treatment areas, each requiring different treatment methods. This segmentation allows the manufacturing process to address specific local requirements without uniformly complicating the entire manufacturing process.
4Manufacturing precision
If treatment areas with different shapes are formed on the substrate side surface, then the precision and uniformity of the display edges and surfaces are improved, but the manufacturing complexity increases
Solution Approach 1:
Different treatment areas have different geometric shapes and surface properties tailored to their specific functions. For example, the first treatment area may have a larger area with higher roughness for mechanical adhesion, while the second treatment area may have a smaller, more precisely defined shape for electrical insulation. This local optimization improves edge precision and surface uniformity.
Solution Approach 2:
The treatment areas are defined not only in the planar dimensions but also in the vertical dimension through different surface roughness and depth profiles. This multi-dimensional approach allows precise control of display edges and surfaces while managing manufacturing complexity.
