MOF Window Structure for Foldable Display Wrinkle Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices suffer from deformation and wrinkling due to repeated folding or bending operations, which compromises their structural integrity and functionality.
Innovation Solution
Incorporation of a metal-organic framework (MOF) in the window base layer or protecting layer of the display device, which exhibits a swelling characteristic under high temperatures and humidity, allowing it to mitigate deformation and wrinkles by reducing stress during folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional window structure is used in a flexible display device, then the device can be folded, but the window becomes deformed or wrinkled due to repeated folding operations
Solution Approach 1:
The window is constructed as a composite structure comprising a window base layer and a window protecting layer, where at least one layer includes MOF material. This composite structure combines the flexibility needed for folding with the stability required to prevent deformation and wrinkling during repeated folding operations.
Solution Approach 2:
The MOF material undergoes parameter changes in response to environmental conditions (temperature and humidity), allowing it to adjust its properties dynamically. This enables the window to maintain structural integrity during folding while adapting to varying operating conditions without permanent deformation.
2Stability of the object's composition
If the window material is made more rigid to prevent deformation, then structural stability improves, but flexibility and foldability are reduced
Solution Approach 1:
The window utilizes thin film structures with MOF material that provide both flexibility for folding and resistance to deformation. The thin film nature allows the window to bend and fold while the MOF component provides structural support that prevents excessive deformation and wrinkling.
Solution Approach 2:
By combining MOF material with window base and protecting layers, the invention creates a composite that exhibits both flexibility and rigidity. The MOF component provides structural stability while the overall composite structure maintains the flexibility needed for foldable display applications.
