Flexible Display Support Assembly for Curling Reliability and Lower Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design of support structures for curling displays is crucial for ensuring reliable curling and unfolding actions, but existing solutions often face challenges in maintaining stability and reducing stress on the flexible display screen.
Innovation Solution
A flexible display apparatus with a two-layer support assembly, comprising a bendable first support member and a plurality of support bars in the second support member, which are arranged parallel to the roller shaft, along with a tension applying component to maintain the flat state and enhance curling reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support structure is added to assist curling and unfolding actions, then the reliability of curling display is improved, but the stress on the flexible display screen increases
Solution Approach 1:
The support structure is divided into multiple support members (first support member and second support member) with different functions. The first support member provides overall structural support while the second support member specifically assists the curling action. This segmentation allows the stress to be distributed across multiple components rather than concentrated on the flexible display screen alone.
Solution Approach 2:
The support members act as intermediary elements between the flexible display screen and the curling mechanism. Instead of the curling mechanism directly acting on the screen, the support members mediate the force transmission, reducing the direct stress on the display screen while still enabling the curling action.
2Reliability
If a support structure is designed to assist curling action, then the curling reliability is improved, but the device complexity increases
Solution Approach 1:
The first support member is designed as a flexible plate-like structure that can bend and deform during the curling and unfolding actions. This flexibility allows the support structure to adapt to the dynamic movements without requiring complex mechanical joints or rigid connections, thereby maintaining simplicity while ensuring reliable curling operation.
Solution Approach 2:
The support structure is designed to be dynamic rather than static. The flexible first support member and the arrangement of support bars allow the structure to change its configuration during curling and unfolding, adapting to the operational requirements without needing complex control mechanisms.
3Duration of action of stationary object
If multiple support members are used to reduce stress on the flexible module, then the service life is improved, but the manufacturing complexity increases
Solution Approach 1:
The first support member and second support member are integrated into a unified support assembly that works together as a cohesive unit. This merging of functions into a single assembled structure simplifies the manufacturing process compared to creating multiple separate complex components, while still providing the stress-distributing benefits of multiple support elements.

AI summary
Disclosed are a flexible display apparatus and a support assembly. The flexible display apparatus includes: a roller shaft; and a flexible module including a rolling and sliding region and a flat region. The rolling and sliding region moves around the roller shaft. The flexible module includes a flexible display screen and the support assembly. The support assembly is disposed on the side of the surface of the flexible display screen facing the roller shaft, and includes a first support member and a second support member. The second support member is disposed on the side of the first support member facing away from the flexible display screen, and includes a plurality of support bars. The plurality of support bars are arranged along the moving direction of the flexible module, and each support bar is consistent with the extending direction of the roller shaft and is fixed on the first support member.
