Flexible OLED Panel Support Structure for Stable Bent-Edge Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible OLED display panels face issues with structural stability and accurate bending due to lack of support between the bent and curved parts, leading to potential dislocation and difficulties in maintaining a consistent bending angle, which affects the display's performance and full-screen display effect.
Innovation Solution
A display panel design incorporating a supporting part between the bent and curved display substrate parts, which provides stable contact and viscosity to prevent movement and dislocation, and a jig with a concave loading surface and supporting surface to facilitate accurate bending and fixation during manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If no supporting part is provided between the bent part and curved display portion, then the device complexity is reduced, but the structural stability and manufacturing precision deteriorate due to potential dislocation and inconsistent bending angle
Solution Approach 1:
A supporting part is introduced as an intermediary element between the bent part and the curved display portion. This supporting part provides mechanical support and maintains the bending angle, preventing dislocation and ensuring structural stability during both manufacturing and operation, while resolving the contradiction between simplicity and reliability.
2Ease of manufacture
If no supporting part is provided between the bent part and curved display portion, then the manufacturing process is simplified, but the manufacturing precision deteriorates due to difficulties in maintaining consistent bending angle
Solution Approach 1:
The supporting part is designed with predetermined geometric features that establish the correct bending angle in advance. During manufacturing, the bent part is positioned on the supporting part which already defines the required curvature, ensuring consistent bending angle without requiring complex real-time control, thus maintaining ease of manufacture while improving precision.
3Manufacturing precision
If a supporting part is added between the bent part and curved display portion, then the structural stability and manufacturing precision are improved, but the device complexity increases
Solution Approach 1:
The supporting part is designed to provide support only at the specific location where bending angle maintenance is critical, rather than throughout the entire display structure. This localized approach achieves the required manufacturing precision and structural stability while minimizing the increase in overall device complexity.
