Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If display panels are arranged along a curved surface to form a complex-shaped display, then the design value and aesthetic appeal are improved, but the reliability deteriorates due to bending-induced defective display
Solution Approach 1:
The display surface is divided into multiple discrete display panels (first display panel and second display panels) that are separately mounted on the curved surface. This segmentation allows each panel to be independently positioned and secured, reducing the risk of bending-induced defects while maintaining the overall complex shape.
Solution Approach 2:
The display panels are pre-fixed to the curved surface using fixing members before final assembly. This preliminary fixation ensures that the panels are securely positioned and prevented from bending during subsequent handling and operation, thereby maintaining display reliability in the complex-shaped configuration.

If driver circuits are positioned to overlap with the display portion to improve space utilization, then the area efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
Different functional circuits are assigned to different regions of the display panel: the gate driver circuit is positioned to overlap with the display portion for space efficiency, while the source driver circuit is positioned to overlap with the non-display portion. This local differentiation optimizes area utilization while managing manufacturing complexity through region-specific circuit placement.
3Shape
If multiple display panels are fixed along a curved surface to achieve a well-designed display, then the aesthetic value is improved, but the mechanical stress increases
Solution Approach 1:
Fixing members are introduced as intermediary components between the display panels and the curved surface support structure. These fixing members distribute and reduce the mechanical stress on the panels while maintaining their fixed positions along the curved surface, thereby preserving both the aesthetic design and the mechanical strength.
