Foldable Display Band Structure for Bending Gap Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible displays in electronic devices are prone to damage due to gaps forming between the display and the frame during bending or flattening, which can cause structural integrity issues.
Innovation Solution
A deformable band with deformation arms and teeth is used to cover the edges of the deformation part between the display parts, providing support and pressure to maintain the display's integrity during bending or flattening, while also preventing foreign particle entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display is allowed to bend or flatten during deformation, then the device achieves transformability between folded and flattened states, but gaps appear between the display and frame causing structural integrity issues
Solution Approach 1:
The patent applies a deformable band with first and second deformation arms that can flex and deform along with the screen. These arms include teeth that engage with the screen surface, creating a flexible protective structure that maintains structural integrity during bending and flattening operations while allowing the device to transform between states.
Solution Approach 2:
The deformable band is designed to dynamically adapt its shape during device transformation. The first and second deformation arms can bend and deform in coordination with the screen's movement, transitioning from a protective covering state to a deformed state that follows the screen's contour during folding and flattening, then returning to the protective state when the device is in its final configuration.
2Strength
If the deformable band applies pressure to maintain display integrity during deformation, then the display durability is improved, but the band itself may be damaged without proper deformation capability
Solution Approach 1:
The deformable band is constructed as a flexible structure with deformation arms that can bend and deform. This flexibility allows the band to apply protective pressure to the screen while accommodating the mechanical stresses of deformation, preventing both screen damage and band failure by distributing forces through the flexible arms and their engaging teeth.
3Object-affected harmful factors
If the deformable band covers the edge of the deformation part to prevent foreign particle entry, then dustproofing is improved, but the band structure becomes more complex
Solution Approach 1:
The deformable band forms a continuous flexible covering over the deformation part edges. This single integrated band structure, with its first and second deformation arms, simultaneously provides dustproofing by sealing the edges while maintaining relative simplicity through its unified design that deforms with the screen rather than requiring multiple separate components.
