Elastic Member Overlap Prevents Creases in Foldable Display Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices face issues with crease generation and foreign substance penetration into openings during repeated folding and unfolding, leading to potential defects in the folding area.
Innovation Solution
The display device incorporates a support member with openings in the folding area, an elastic member overlapping these openings, and adhesive members to secure the elastic member and prevent foreign substance penetration, while allowing for easy folding and unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a support member with openings is disposed on the bottom surface of the display panel in the folding area, then crease generation is prevented, but foreign substances can penetrate into the openings during folding and unfolding
Solution Approach 1:
An elastic member is introduced as an intermediary component between the support member with openings and the external environment. This elastic member covers the openings during folding operations, preventing foreign substances from penetrating into the openings while allowing the support member to maintain its crease-preventing function. The elastic member acts as a protective barrier that is present only when needed during folding and unfolding operations.
2Adaptability or versatility
If the display panel is made flexible to enable folding, then portability and adaptability are improved, but reliability deteriorates due to crease generation and potential defects in the folding area
Solution Approach 1:
The elastic member serves as a protective intermediary that is specifically deployed in the folding area to prevent foreign substance penetration and crease generation. This component is positioned between the flexible display panel and the external environment, providing localized protection only where folding occurs, thereby maintaining the overall flexibility and adaptability of the display panel while improving reliability in the critical folding region.
Solution Approach 2:
The elastic member is implemented as a flexible thin film or shell structure that can accommodate the folding movements of the display panel. This flexible protective layer maintains its integrity during repeated folding and unfolding operations, preventing external contaminants from entering the openings while allowing the display panel to maintain its flexible, foldable characteristics.

Function Achieved in This Case
This configuration enhances the reliability of the display device by preventing crease formation and foreign substance penetration, thus maintaining the integrity of the folding area even with repeated use.
Implementation Method 1
an elastic member disposed on a bottom surface of the support member and overlapping the openings in the folding area
Implementation Method 2
a first adhesive member disposed between the support member and the elastic member
