Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple small-size sub-display panels are spliced to obtain a large-size display screen, then the display screen size is increased, but seam-related defects and display uniformity deteriorate
Solution Approach 1:
A flexible strip-shaped display structure is introduced as an intermediary component between adjacent sub-display panels. This strip includes a display region that fills the gap between panels and a foldable portion that enables seamless connection. The strip-shaped display structure acts as a mediator that eliminates visible seams while maintaining display uniformity across the entire large-size screen.
Solution Approach 2:
The strip-shaped display structure extends in the vertical direction (along the splicing direction) rather than only in the horizontal direction. By adding this vertical extension dimension, the display structure can cover the gap between sub-panels and provide seamless splicing, thereby improving display uniformity while maintaining large screen size.
2Manufacturing precision
If a strip-shaped display structure with foldable portion is used to cover gaps between sub-display panels, then display uniformity is improved, but device complexity increases
Solution Approach 1:
The strip-shaped display structure incorporates a foldable portion made of flexible materials that can be bent and folded. This flexibility allows the structure to adapt to the gap between sub-display panels and be stacked against the back surface, achieving seamless splicing without requiring complex mechanical mechanisms or additional support structures.
Solution Approach 2:
The foldable portion of the strip-shaped display structure is designed to be folded back and stacked against the back surface of the sub-display panel when not in use. This nesting arrangement minimizes the occupied space and simplifies the overall device structure while maintaining the capability to cover gaps and improve display uniformity.
3Manufacturing precision
If the extension part is bent away from the light exit side to cover gaps, then seamless splicing is achieved, but the structural stability deteriorates
Solution Approach 1:
The strip-shaped display structure utilizes flexible materials that can be bent and folded without compromising structural integrity. The foldable portion can be bent away from the light exit side to cover gaps between sub-panels, and the flexibility of the material ensures that the structure remains stable and maintains its functional properties during bending and stacking.
