Flexible Display Warpage Prevention via Segmented Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display panels with flexible substrates tend to warp during operation, compromising display quality and user comfort due to the need to balance flexibility in storage and stiffness in extended states.
Innovation Solution
A display apparatus comprising a cover, slide rail component with elastic elements and bumps, and a support component with hollow portions, which fixes the sliding block on a rail and reduces stress on the connection surface by allowing the flexible display component to bend in conformity with a guide roller, enhancing flatness and resistance to external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a flexible substrate is used to enhance flexibility and impact resistance, then flexibility and durability are improved, but the display panel becomes prone to warpage during operation
Solution Approach 1:
The support component is divided into multiple first support portions and second support portions that are distributed across the display panel. These segmented support structures provide localized reinforcement without compromising the overall flexibility of the flexible substrate, effectively preventing warpage while maintaining the required flexibility.
Solution Approach 2:
The support component is strategically positioned at specific locations where warpage is most likely to occur during display panel operation. By providing targeted support only where needed rather than uniformly across the entire panel, the design maintains flexibility in non-critical areas while preventing warpage in critical regions.
2Length of moving object
If the flexible display panel is made thinner to improve flexibility, then flexibility is enhanced, but the panel becomes more susceptible to warpage and deformation
Solution Approach 1:
The support component is segmented into multiple discrete support portions rather than a single continuous structure. This segmentation allows the thin flexible panel to maintain its flexibility while receiving distributed support at multiple locations, preventing warpage without requiring increased thickness.
Solution Approach 2:
The support component appears to be constructed from materials with different mechanical properties than the flexible substrate, creating a composite structure that combines the flexibility of the thin substrate with the rigidity needed to prevent warpage, thereby maintaining both thinness and structural stability.
