Flexible Display Support Structure for Bending Region Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display panels are prone to damage due to frequent pressing at the edge region, leading to a short service lifetime, as the existing structure cannot effectively distribute pressing forces without causing excessive depression and damage to the bending region.
Innovation Solution
A flexible display device design featuring a support structure with a bending region, extension region, and accommodation space, where the support structure is located within the accommodation space and extends into the bending space, providing additional support and reducing the impact of pressing forces on the bending region, and includes features like a round corner structure, adhesive connections, and a filling structure to enhance durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cover plate is made very thin to maintain flexibility, then the flexibility and flexibility of the display panel is improved, but the pressing force bearing capacity deteriorates
Solution Approach 1:
The support structure is divided into multiple components: a first support structure extending from the bending region, a second support structure extending from the extension region, and a connecting structure linking them. This segmentation allows each component to bear specific portions of the pressing force, distributing the load rather than relying on the thin cover plate alone.
Solution Approach 2:
The support structure acts as an intermediary element between the pressing force and the bending region. It receives the pressing force from the cover plate and transfers it to the main structure region and extension region, preventing direct transmission of excessive forces to the fragile bending region.
2Adaptability or versatility
If the bending region is made flexible to enable bending, then the flexibility is improved, but the resistance to pressing force deteriorates
Solution Approach 1:
The support structure is pre-installed in the accommodation space to provide cushioning protection before pressing forces are applied. The first support structure, second support structure, and connecting structure form a protective framework that absorbs and distributes pressing forces, preventing damage to the bending region before excessive forces can cause harm.
Solution Approach 2:
The support structure combines rigid and flexible elements to create a composite system. The connecting structure includes a first flexible portion and a second flexible portion that can deform to absorb energy, while the first support structure and second support structure provide rigid support. This composite approach maintains flexibility while enhancing resistance to pressing forces.
3Strength
If the accommodation space is created to house the support structure, then the support capability is improved, but the structural complexity increases
Solution Approach 1:
The support structure is nested within the existing accommodation space of the display panel. The first support structure, second support structure, and connecting structure are arranged to fit within the space already defined by the bending region and extension region, utilizing existing structural boundaries rather than adding entirely new structural elements.
Solution Approach 2:
The support structure is merged with the existing display panel structure. The first support structure connects to the bending region, the second support structure connects to the extension region, and the connecting structure integrates these elements into a unified support system that works together with the existing panel architecture.
