Curved Display Panel Edge Recess Structure Against Bending Stripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The periphery region of soft display panels is prone to stripping due to bending, which affects the structural integrity and process yield.
Innovation Solution
A substrate with recesses in the periphery region, featuring a first and second non-organic layer with an organic layer in between, where the second non-organic layer is disposed on the first non-organic layer at the central portion of the recesses, enhancing the structural reinforcement and reducing the risk of turbulent flow and gap formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the periphery region of soft display panels is reinforced to prevent stripping due to bending, then the structural integrity is improved, but the device complexity increases
Solution Approach 1:
The periphery region is divided into multiple recesses that are distributed across the panel. Each recess acts as an independent reinforcement unit, segmenting the overall reinforcement task into manageable portions that collectively strengthen the periphery without requiring a monolithic complex structure
Solution Approach 2:
Recesses are strategically positioned in the periphery region where bending stresses are most critical. The reinforcement is localized to specific areas rather than applied uniformly across the entire panel, providing targeted strength enhancement where needed most while maintaining simplicity in other regions
2Reliability
If recesses are introduced in the periphery region to enhance adhesion, then the reliability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The recesses are formed in the substrate before the active region and other sensitive components are manufactured. This preliminary formation of recesses establishes the reinforcement framework early in the manufacturing process, allowing subsequent layers to be deposited around the pre-defined recess structures without requiring high-precision alignment during later stages
3Strength
If multiple layers are disposed in recesses to strengthen the periphery, then the strength is improved, but the device complexity increases
Solution Approach 1:
Multiple layers are nested within the recess structures, with each layer contained within the boundaries of the recess. The first non-organic layer, organic layer, and second non-organic layer are sequentially disposed within the same recess footprint, creating a nested configuration that provides reinforcement without lateral expansion or complex spatial arrangements

AI summary
An electronic device is provided. The electronic device includes a substrate having an edge, an active region located on the substrate, a first non-organic layer and a second non-organic layer disposed on the substrate, and an organic layer disposed between the first non-organic layer and the second non-organic layer. The plurality of recesses are located between the active region and the edge in a top view. In a cross-sectional view, the second non-organic layer is disposed on the first non-organic layer, and the first non-organic layer directly contacts the second non-organic layer at a point which is located in a central portion of one of the plurality of recesses. A portion of the organic layer is located in the one of the plurality of recesses.
