Solution Overview
Problem
Conventional flexible display devices require complex structures and multiple parts to fold, leading to exposed joints, aesthetic issues, and inability to provide continuous images, while also lacking touch sensing convenience in bent areas.
Innovation Solution
A flexible display device with a bendable and returnable display panel using bending actuators, a housing, and touch screens, allowing users to bend and flatten sections as needed, while maintaining touch sensing functionality and preventing damage through magnetic and adhesive members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate display panels are connected through a connecting part to enable folding, then the display device can be bent, but the joint is exposed to the outside deteriorating external appearance and cannot provide a continuous image
Solution Approach 1:
The patent merges the display panel and connecting part into a single integrated flexible display panel structure. The connecting part is no longer a separate component but is integrated into the panel itself, eliminating exposed joints and providing a continuous image across the entire display surface while maintaining folding capability.
Solution Approach 2:
The patent employs a flexible display panel that can be bent without requiring separate connecting parts. The panel itself is designed with flexible materials and structures that allow it to fold smoothly, eliminating the need for rigid connecting components that would expose joints and disrupt the external appearance.
2Adaptability or versatility
If a connecting part is used to fold the display panel, then the display device can be bent, but the structure becomes complicated and the number of parts is inevitably increased
Solution Approach 1:
The patent combines multiple functions into the flexible display panel itself, eliminating the need for separate connecting parts. The panel integrates both the display function and the folding mechanism, significantly reducing structural complexity and the total number of components.
Solution Approach 2:
The flexible display panel serves multiple functions: it provides the display surface, enables folding, and maintains structural integrity. This multi-functional design eliminates the need for dedicated connecting parts, simplifying the overall structure.
3Adaptability or versatility
If the display panel is made flexible to enable bending, then the display device can be folded, but touch sensing convenience in the bent area is compromised
Solution Approach 1:
The patent applies different properties to different areas of the flexible display panel. The bent area is specifically designed to maintain touch sensing functionality through localized structural adjustments and material properties, ensuring that touch convenience is preserved even in the folded state while other areas maintain their original characteristics.
