Solution Overview
Problem
Foldable display devices face challenges in durability against external impacts due to deformation of support members, which can lead to damage and electrostatic discharge issues.
Innovation Solution
A foldable display device design incorporating a support member with a pattern layer made of metal material surrounding the folding area, providing additional protection and forming a ground path to prevent deformation and electrostatic discharge, while the support layers are made of materials like glass or plastic and spaced apart from the pattern layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a support member with high rigidity is used to prevent deformation of the display module, then the display module is protected from user touch deformation, but the support member itself is vulnerable to external impacts causing device damage
Solution Approach 1:
The support member is divided into multiple layers: a first support layer overlapping the first non-folding area, a second support layer overlapping the second non-folding area, and a pattern layer overlapping the folding area. This segmentation allows each layer to be optimized for specific functions - the support layers provide rigidity against user touch while the pattern layer provides impact protection and electrostatic discharge prevention
Solution Approach 2:
The support member uses composite material structure combining different materials with complementary properties. The first and second support layers use materials suitable for preventing display module deformation, while the pattern layer uses metal material for impact resistance and electrostatic discharge protection, creating a composite structure that addresses both requirements
2Stability of the object's composition
If the support member is made rigid to maintain structural integrity, then the display module remains stable, but electrostatic discharge can occur during folding operations
Solution Approach 1:
The pattern layer acts as an intermediary between the rigid support layers and the folding area. This metal pattern layer provides a conductive path that safely dissipates electrostatic charge generated during folding operations, while the support layers maintain structural integrity. The pattern layer mediates between the need for rigidity and the need to prevent electrostatic discharge
