Flexible Display Gap Control via Limiting Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices face issues such as scratching and unstable forces due to warping tail ends and high arches during rolling and sliding, which can lead to contact with the housing and damage.
Innovation Solution
A flexible display device design incorporating a housing, a flexible display screen, a support member, and a rotatable sliding-roller with a limiting structure, such as rigid tracks and magnetic structures, to maintain a gap between the screen and the housing, preventing contact and ensuring flatness during rolling and sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexible display screen is rolled and slid without a limiting structure, then the display device achieves compactness and portability, but the display module may be scratched due to warping tail end and high arch formation
Solution Approach 1:
A limiting structure comprising rigid tracks and limiting members is introduced as an intermediary between the flexible display screen and the housing. The rigid tracks guide the rolling and sliding motion, while the limiting members prevent the display screen from contacting the housing, thus avoiding scratches and damage during portability operations
Solution Approach 2:
The limiting structure is pre-configured within the housing before the flexible display screen undergoes rolling and sliding. The rigid tracks are predetermined in position and shape, and the limiting members are pre-positioned to maintain appropriate gaps, ensuring that the display screen is protected from warping and damage before actual use
2Device complexity
If the flexible display screen is allowed to contact the housing during rolling, then the structure is simplified, but unstable force is applied to the display module causing damage
Solution Approach 1:
The limiting structure acts as a mediator that maintains a controlled gap between the flexible display screen and the housing during rolling and sliding. This prevents direct contact and unstable force application while maintaining structural organization through predetermined rigid tracks and limiting members

AI summary
A flexible display device is provided, including: a housing, a flexible display screen, a support member and a sliding-roller. The support member is located between the flexible display screen and the sliding-roller, and is configured for driving the flexible display screen to be rolled on the sliding-roller. The sliding-roller is rotatable and is arranged in the housing. The flexible display device further includes a limiting structure provided between the support member and the housing for maintaining a gap between the flexible display screen and the housing. A display terminal is further provided.
