Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional foldable displays exhibit gaps after flattening, affecting display effectiveness due to the need for space in the folding process and stress on flexible AMOLED screens during folding.
Innovation Solution
A foldable display module with deformable members, such as airbags, between support mechanisms and flexible screens that expand in volume to seamlessly splice the screens in a flat state, reducing stress and eliminating gaps when folded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional splicing method is used for foldable screens, then the support mechanisms can accommodate movement during folding, but large gaps appear between screens after unfolding
Solution Approach 1:
The support mechanisms are designed to be movable rather than fixed, allowing them to dynamically adjust position during folding and unfolding operations. This dynamic adjustment enables the mechanisms to accommodate screen movement while maintaining precise alignment in the unfolded state, eliminating gaps between screens.
Solution Approach 2:
The invention changes the positional parameters of the support mechanisms based on the folding state. During folding, the mechanisms are positioned to accommodate movement; when unfolded, they are repositioned to achieve precise screen alignment. This parameter change resolves the contradiction between operational ease and alignment precision.
2Adaptability or versatility
If space is allocated for support mechanism movement during folding, then folding operation is enabled, but large gaps appear after unfolding
Solution Approach 1:
The display system is segmented into flexible screens and separate support mechanisms. This segmentation allows the support mechanisms to be independently positioned and adjusted without affecting the continuous display area of the screens when unfolded, while still providing necessary movement space during folding operations.
Solution Approach 2:
The support mechanisms operate in a dimension separate from the display plane, allowing them to move and adjust without creating gaps in the display area. By relocating the mechanisms to another dimensional space, the invention maintains full display coverage while enabling folding adaptability.
3Reliability
If flexible AMOLED screens are used for splicing, then high contrast and wide viewing angles are achieved, but stress during folding causes display gaps
Solution Approach 1:
The movable support mechanisms act as intermediaries between the flexible AMOLED screens and the folding structure. These mechanisms absorb and distribute stress during folding, protecting the screens from damage while maintaining display quality. The intermediaries enable the fragile flexible screens to withstand repeated folding without developing gaps or defects.
