Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple light boards are combined (tiled) to form large-sized display devices, then the display size is increased, but seams become visible at the border between adjacent tiles and misalignment occurs
Solution Approach 1:
Positioning marks are pre-formed on the light-emitting structure and carrying substrate before assembly. These marks serve as alignment references that guide the precise positioning of adjacent light boards during the tiling process, eliminating misalignment issues while maintaining large display size.
Solution Approach 2:
Positioning marks act as intermediary elements between adjacent light boards. By providing visual or physical reference points at the boundaries of tiled displays, these marks enable precise alignment and reduce the visibility of seams between adjacent tiles.

3Manufacturing precision
If positioning marks are formed on light-emitting structure and carrying substrate, then alignment precision is improved, but manufacturing process complexity increases
Solution Approach 1:
The positioning marks are integrated into the existing light-emitting structure and carrying substrate manufacturing processes. By combining the positioning mark formation with the manufacturing of these components, the patent avoids adding separate manufacturing steps, thereby maintaining alignment precision while minimizing increases in manufacturing process complexity.
