Flexible Members for Foldable Display Stress Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices often suffer from excessive stress during folding operations, leading to potential damage of the display panel due to rigid fixation methods.
Innovation Solution
A display device design featuring flexible first and second members, with elastic properties, that are thicker than their adhesion layers, covering overlapping areas between supports and the display panel, to absorb deformation and distribute stress evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the display panel is firmly fixed to the support with adhesive, then the fixation strength is improved, but stress is easily applied to the display panel during folding operation, leading to potential damage
Solution Approach 1:
The patent introduces flexible members (first and second members) that are more flexible than the display panel itself. These members are fixed to the supports and adhere to the display panel, creating a flexible intermediary layer that can accommodate bending stresses during folding operations while maintaining secure fixation.
Solution Approach 2:
The patent changes the flexibility parameter of the fixation system by introducing members with specific flexibility characteristics. The first and second members are designed to be more flexible than the display panel, allowing them to deform preferentially during folding, thereby protecting the display panel from excessive stress.
2Adaptability or versatility
If the display panel is made foldable by connecting supports, then the adaptability is improved, but excessive stress is applied to the display panel during bending, causing potential damage
Solution Approach 1:
The patent introduces flexible members as intermediary elements between the supports and the display panel. These members act as mediators that absorb and distribute the mechanical stress generated during folding operations, preventing direct transmission of excessive stress to the display panel while enabling the foldable functionality.
Solution Approach 2:
The flexible members are pre-installed on the supports before the display panel is assembled. These members provide beforehand cushioning by being positioned to absorb and distribute stresses that will occur during subsequent folding operations, protecting the display panel from damage before the stress is applied.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents excessive stress on the display panel, reducing the risk of damage during bending by allowing flexible members to absorb deformation, thereby ensuring the panel's integrity.
Implementation Method 1
a first member that is fixed to the first support and is more flexible than the display panel; a second member that is fixed to the second support and is more flexible than the display panel

AI summary
A display device according to the disclosure includes: a first support that supports a display panel; a second support that supports the display panel; a connecting portion that connects the first support and the second support so that the display panel can be bent; a first member that is fixed to the first support and is more flexible than the display panel; a second member that is fixed to the second support and is more flexible than the display panel; a first adhesion layer that adheres the first member to at least a portion of a first surface opposite to a display surface of the display panel; and a second adhesion layer that adheres the second member to at least another portion of the first surface.
