Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel supports are designed specifically for deformable regions or directions, limiting their universal applicability to flexible display devices such as foldable, rollable, stretchable, or slidable displays.
Innovation Solution
A display panel support system comprising multiple stacked metal sheets with varying thicknesses, materials, and patterns, providing high rigidity and low elasticity, allowing universal application across different deformable regions and directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a panel support is designed specifically for deformable regions or directions, then the support provides adequate structural strength for that specific region, but the device complexity increases and universal applicability is limited
Solution Approach 1:
The patent applies universality by designing a panel support with multiple support members arranged in different directions that can serve multiple deformable regions. The support structure is configured to provide adequate structural strength for various deformation types (folding, rolling, stretching, sliding) without requiring separate designs for each region, thereby reducing device complexity while maintaining strength.
Solution Approach 2:
The patent segments the panel support into multiple support members (first support member, second support member, third support member) with different thicknesses and orientations. Each support member can be independently optimized for specific deformation directions while collectively providing comprehensive support across all deformable regions, resolving the contradiction between strength and complexity.
2Stability of the object's composition
If multiple support members with different thicknesses are used, then the panel support achieves high rigidity and low elasticity in all directions, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by using support members with different thicknesses (0.05-0.2mm for first and third support members, 0.1-0.15mm for second support member) in specific locations where different rigidity characteristics are needed. This localized variation in thickness allows optimization of rigidity and elasticity properties for different deformation directions while maintaining manageable manufacturing precision through standardized thickness ranges.
3Adaptability or versatility
If a single panel support design is applied to all flexible display devices, then adaptability is improved, but the support may not provide optimal strength for specific deformable regions
Solution Approach 1:
The patent achieves universality through a multi-functional panel support design that can be applied to various flexible display devices (foldable, rollable, stretchable, slidable) without requiring separate designs. The support structure with multiple members in different directions provides adequate strength for all deformation types while maintaining a single universal design, thereby improving adaptability without sacrificing support strength.

AI summary
A display device includes a display panel and a panel support. The display panel includes a first surface and a second surface opposite to the first surface. The panel support is disposed on the first surface. The panel support includes a first support member including first support portions that extend in a first direction and are spaced apart from each other. The panel support includes a second support member including second support portions that extend in a second direction intersecting the first direction and are spaced apart from each other. The panel support includes a third support member including third support portions that extend in a third direction intersecting the first and second directions and are spaced apart from each other. The second support member is disposed between the first and third support members. The second support member is attached to the first and third support members.
