Flexible Display Panel Curved Edge Support Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable flexible display devices have a monotonous square shape, making it difficult to achieve a curved surface design, which results in an unsatisfactory handfeel for consumers when holding or sliding the device.
Innovation Solution
A flexible display panel with a support structure that includes a first bending region and a second bending region, where the support has a hollowed-out structure corresponding to the second bending region, allowing for a curved surface design by forming a specific curvature at the edge of the panel, enhancing the handfeel and usability.

Engineering Contradiction Analysis
1Shape
If a square shape is used for the foldable flexible display device, then the device structure is simple and easy to manufacture, but the handfeel and aesthetic quality are monotonous and unsatisfactory
Solution Approach 1:
The support is divided into multiple regions: a first support region with a first support surface, a second support region with a second support surface, and a connection region connecting them. This segmentation allows different regions to have different functions - the first support region provides structural support, the second support region forms the curved surface, and the connection region enables smooth transition between them, thus achieving curved surface design without excessive complexity.
Solution Approach 2:
The invention transitions from a traditional flat 2D display surface to a 3D curved surface by introducing a connection region with a smooth transition surface that connects the first support surface and the second support surface. This dimensional change creates an aesthetically pleasing curved profile while maintaining manufacturability through defined geometric transitions.
2Ease of operation
If a curved surface design is implemented, then the handfeel and aesthetic quality are improved, but the device structure becomes more complex and difficult to manufacture
Solution Approach 1:
The support structure is segmented into functional regions with distinct roles. The first support region maintains structural integrity, the second support region provides the curved surface for improved handfeel, and the connection region with smooth transition surface enables the curvature change. This segmentation manages complexity by assigning specific functions to specific regions.
Solution Approach 2:
Different regions of the support are given different local qualities appropriate to their function. The first support region has a flat support surface for stability, the second support region has a curved surface for ergonomic handfeel, and the connection region has a smooth transition surface. This local differentiation optimizes performance in each region without requiring complex structures throughout the entire device.
