Flexible Display Support Bars with Rotating Joints for Flatness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices struggle to maintain flatness when unfolded, leading to surface quality degradation and reduced portability due to deformation between support bars.
Innovation Solution
A display device design featuring a support layer with protruding support bars and rotating joints, where at least two support bars are inserted into grooves in the joints, providing increased rigidity and maintaining flatness of the display module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible display panel is made deformable to provide portability, then user convenience and portability are improved, but the display panel cannot maintain flatness when unfolded
Solution Approach 1:
The support structure is divided into multiple support bars that can be segmented and positioned at different locations. These support bars work together to maintain the flatness of the display panel when unfolded, while allowing the overall structure to be flexible and portable.
Solution Approach 2:
The support bars are configured to be movable relative to each other, allowing the structure to dynamically adapt between folded and unfolded states. This dynamic configuration enables the display to maintain flatness during use while being flexible for portability.
2Shape
If support bars are added to maintain flatness, then surface quality is improved, but the device complexity increases
Solution Approach 1:
The support structure utilizes thin support bars that are flexible yet effective at maintaining surface quality. These thin-film-like support elements provide the necessary structural support without adding significant complexity to the overall device design.
Solution Approach 2:
Instead of providing continuous support across the entire display area, support bars are strategically positioned at key locations where they provide sufficient support to maintain surface quality. This partial support approach reduces structural complexity while achieving the desired surface maintenance.
3Reliability
If multiple support bars are used to prevent deformation, then reliability is improved, but the ease of manufacture decreases
Solution Approach 1:
Multiple support bars are merged into a unified structure that works together as an integrated system. This combining of support elements simplifies the manufacturing process by reducing the number of separate components that need to be assembled, while still maintaining the reliability needed to prevent deformation.
Solution Approach 2:
The support bars are designed with universal characteristics that allow them to serve multiple functions: maintaining flatness, providing structural support, and enabling portability. This multi-functionality reduces the need for specialized components, thereby simplifying manufacturing and assembly.
