Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices with flexible and foldable designs face challenges in achieving a balance between high strength and flexibility, particularly in terms of impact resistance and durability, which is essential for protecting the display module during various usage scenarios.
Innovation Solution
A display device with a support module comprising a base layer of glass, carbon, or aramid fibers, a support layer with resin, and strategically placed spacers and filling members, along with adhesive layers, to enhance both impact resistance and flexibility by distributing forces effectively during folding and external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a support module with high strength material is used to protect the display module, then impact resistance is improved, but flexibility deteriorates
Solution Approach 1:
The support module is divided into multiple layers with distinct functions: a base layer for flexibility and a support layer with openings for impact resistance. This segmentation allows each layer to optimize its specific function while working together as a unified structure.
Solution Approach 2:
The support layer is provided with openings in specific regions corresponding to the folding area of the display module. This local modification allows the support module to be rigid in non-folding areas for impact protection while remaining flexible in the folding areas for bendability.
2Reliability
If a rigid support structure is used to protect the display module, then durability is improved, but foldability deteriorates
Solution Approach 1:
The support module is segmented into a base layer and a support layer with openings, allowing the structure to be rigid where needed for durability while maintaining flexibility in folding regions.
Solution Approach 2:
The base layer is made of flexible materials such as glass fiber, carbon fiber, or aramid fiber combined with resin, providing a flexible foundation that maintains structural integrity during folding operations.
3Strength
If a uniform support structure is used across the entire display module, then impact resistance is improved, but folding performance deteriorates
Solution Approach 1:
The support layer is provided with openings in specific regions corresponding to the folding area, creating local variations in structural properties that enable folding performance while maintaining overall impact resistance in non-folding areas.
Solution Approach 2:
The support module is divided into regions with different structural characteristics: solid base layer for impact resistance and support layer with openings for folding flexibility, allowing optimized performance in each region.

AI summary
A display device includes: a display module comprising a first non-folding area, a second non-folding area, and a folding area between the first non-folding area and the second non-folding area; and a support module under the display module to support the display module, the support module including: a base layer comprising at least one of a glass fiber, a carbon fiber, or an aramid fiber; and a support layer having an opening overlapping the folding area, wherein the support layer is on at least one of upper or lower portions of the base layer.
