Flexible Display Module With Multi-Supporter Hinge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible display devices face a trade-off between portability and screen size, with larger screens compromising portability and shorter lifetimes due to unnecessary bending when folded, and multiple-fold designs increasing thickness, limiting both size and longevity.
Innovation Solution
A flexible display module comprising interconnected supporters and a hinge mechanism that allows the screen to be completely folded inward and outward, enabling partial hiding inside the device while maintaining display functionality and reducing bending stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display device has a larger display screen, then the display size is improved, but the portability deteriorates
Solution Approach 1:
The flexible screen is nested within the display device housing through a multi-stage folding mechanism. The screen can be completely folded inward and stored inside the device body, with supporter structures providing nested support at different folding stages. This allows a large display screen to be compacted into a small portable form factor.
Solution Approach 2:
The display device employs dynamic folding mechanisms with multiple supporters that can rotate between different positions. The supporters transition between extended and retracted states, enabling the screen to dynamically change from a large unfolded display to a compact folded state for portability.
2Length of moving object
If the flexible screen is folded repeatedly for portability, then the portability is improved, but the lifetime deteriorates
Solution Approach 1:
The display device is designed with a multi-stage folding mechanism that guides the screen through predetermined folding paths. The supporters are pre-positioned to support the screen at each folding stage, preventing unpredictable bending and reducing stress concentration that would accelerate screen degradation.
Solution Approach 2:
The folding mechanism changes the bending radius and folding angle parameters during the folding process. By controlling these parameters through the supporter structures, the screen experiences more uniform and less severe bending stresses compared to simple single-axis folding, thereby extending screen lifetime.
3Length of moving object
If a single-fold mechanism is used for portability, then the portability is improved, but the display size capability deteriorates
Solution Approach 1:
The folding mechanism is segmented into multiple independent supporters (first supporter, second supporter, third supporter) that can rotate independently. This segmentation allows the screen to be folded in multiple stages, achieving compact thickness while maintaining the capability to support a large display screen area when fully extended.
Solution Approach 2:
The multi-stage folding mechanism utilizes multiple rotational dimensions rather than a single folding axis. The supporters rotate in sequence around different axes, enabling the screen to achieve compact thickness in one dimension while preserving the ability to maintain large display area when unfolded, effectively using dimensional transitions to resolve the contradiction.

AI summary
A flexible display module and an electronic apparatus comprising the flexible display module are disclosed. The flexible display module comprises a first supporter, a second supporter, a third supporter, a connector, and a flexible screen. The first supporter, the connector, the second supporter, and the third supporter are connected rotatably with one another in sequence. The first supporter, the second supporter, and the third supporter are used for supporting the flexible screen together. According to the present disclosure, not only large size display can be provided, but also part of contents can be displayed after the flexible screen is completely folded. The flexible screen can be completely folded after inward folding once and outward folding once. In this manner, part of the flexible screen can be hidden inside the display device, and the other part of the flexible screen can be exposed outside the display device. The flexible screen has a good portability and a long lifetime.
