Foldable Display Support Structure for Bending Flatness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for flexible display panels in foldable devices fail to effectively support the bending portion, leading to bulging and poor flatness, which results in creases and potential film stripping, reducing the display's service life and display quality.
Innovation Solution
A support device with a rotating shaft support and multiple support components connected to the bending and non-bending portions of the flexible display panel, providing comprehensive support to maintain flatness and prevent bulging during folding and unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple support device is used for flexible display panels, then the device complexity is reduced, but the bending portion cannot be effectively supported, leading to bulging and poor flatness
Solution Approach 1:
The support device is divided into multiple support components (first support component, second support component, third support component, fourth support component) that are distributed at different positions (first end, second end, middle position) of the bending portion. Each support component independently supports specific regions, collectively providing comprehensive support to maintain flatness without requiring a monolithic complex structure.
Solution Approach 2:
Support components are strategically positioned at critical locations (ends and middle of bending portion) where support is most needed. The first and second support components are located at the ends of the bending portion, while the third and fourth support components are positioned at the middle, providing localized support precisely where bulging is most likely to occur.
2Reliability
If existing support devices are used, then the structure is simpler, but creases and film stripping occur, reducing display service life
Solution Approach 1:
The support device uses multiple discrete support components rather than a single continuous support structure. This segmentation allows each component to independently prevent creasing at its specific location, collectively providing comprehensive protection against film stripping and extending display service life.
Solution Approach 2:
Support components are positioned at critical stress points (ends and middle of bending portion) where creases are most likely to form during folding and unfolding. This localized support at high-stress areas prevents film stripping at these vulnerable points, thereby extending the overall service life of the display.
3Manufacturing precision
If comprehensive support is provided to maintain flatness, then the display quality is enhanced, but the device structure becomes more complex
Solution Approach 1:
The support device is segmented into multiple identical or similar support components positioned at different locations. This modular approach achieves comprehensive support and maintains flatness through the collective action of simple, repetitive units rather than a single complex structure, facilitating easier manufacturing and assembly.
Solution Approach 2:
Support components are positioned at specific critical locations (ends and middle of bending portion) where maintaining flatness is most important for display quality. This targeted local support at key positions achieves overall flatness maintenance with minimal necessary support points.
