Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stretchable OLED display panels face distortion issues during stretching, leading to poor display performance due to shear stress on display islands and gaps in the connection bridge structure.
Innovation Solution
A display panel design featuring a flexible substrate and a support substrate jointed through a magnetic field generated by first and second magnetic units. The magnetic units, comprising magnetic devices or membranes, ensure the flexible substrate remains stable and undistorted during stretching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible OLED display panel uses a connection bridge structure to enable stretching, then the display panel achieves flexibility and stretchability, but the display islands experience shear stress and the connection bridges create gaps leading to distortion during stretching
Solution Approach 1:
The display panel is divided into discrete display islands separated by connection bridges, allowing independent movement of each island during stretching while maintaining overall connectivity. This segmentation enables the display to accommodate deformation without creating continuous stress paths that would cause distortion.
Solution Approach 2:
Magnetic units are introduced as intermediary elements between the display islands and the flexible substrate. These magnetic units provide a non-mechanical coupling mechanism that maintains relative positioning stability while allowing the flexible substrate to stretch, eliminating direct mechanical stress transmission to the display regions.
2Stability of the object's composition
If magnetic units are introduced to prevent distortion during stretching, then display region stability is improved, but the device complexity increases due to additional magnetic components
Solution Approach 1:
The magnetic units are integrated directly into the flexible substrate structure, combining the substrate and magnetic components into a unified element. This merging eliminates the need for separate magnetic component assemblies, reducing overall device complexity while maintaining the stabilizing magnetic effect during stretching.
