Foldable Display Side-Bending Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable display screens are fragile and prone to damage when exposed externally, leading to display issues or dark spots after contact with hard objects or falls.
Innovation Solution
A foldable display screen design that includes a transparent protective structure covering the side-surface bending display area, which is fixedly connected to a frame and uses a flexible adhesive to secure the protective structure, ensuring protection without affecting the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display screen is bent to create a side-surface bending display area, then the display versatility and viewing angles are improved, but the screen becomes more susceptible to damage from hard objects and falls
Solution Approach 1:
The display screen is segmented into different functional areas: a front display area, a back display area, and a side-surface bending display area. The transparent protective structure is further segmented to cover only the vulnerable side-surface bending area, allowing each region to serve its specific purpose while the protected region gains enhanced durability
Solution Approach 2:
A transparent protective structure is introduced as an intermediary element between the vulnerable side-surface bending display area and external harmful factors (hard objects, impacts). This mediator provides mechanical protection while maintaining optical transparency, allowing the display to remain visible and functional during side-viewing angles
2Reliability
If a protective structure is added to cover the side-surface bending display area, then the screen durability is improved, but the device complexity increases
Solution Approach 1:
The protective structure is designed as a thin, transparent film or shell that conforms to the bent shape of the side-surface display area. This flexible protective layer provides necessary mechanical strength and impact resistance without adding significant bulk, weight, or structural complexity to the overall device
Solution Approach 2:
The protective structure extends into the spatial dimension by covering the side-surface bending area that wraps around the edge of the device. This three-dimensional configuration provides comprehensive protection across multiple surfaces and angles without requiring complex multi-layer assemblies
