Foldable Display Bezel Grooves to Protect Layer Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with slim bezels are prone to display slip phenomena during folding or external impacts, leading to potential damage of the protective layer due to collisions with the housing structure.
Innovation Solution
A foldable electronic device design featuring a slim bezel with inclined inner circumferential surfaces in grooves for the protective layer edges, ensuring the edges are recessed and protected, and a polymer layer with protrusions to enhance coverage and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a slim bezel is implemented in a foldable electronic device, then the device achieves a more compact and elegant appearance, but the protective layer becomes prone to slip and collide with the housing structure during folding or external impacts
Solution Approach 1:
The housing decoration is divided into multiple grooves (first groove, second groove, third groove) positioned at different locations. Each groove independently receives and protects a specific edge portion of the protective layer, preventing slip and collision during folding or external impacts while maintaining a slim bezel appearance.
Solution Approach 2:
The grooves in the housing decoration serve as intermediary structures between the protective layer edges and the housing. These grooves receive the edges of the protective layer and prevent direct contact and collision with the housing structure, thereby protecting the protective layer while enabling a slim bezel design.
2Shape
If the protective layer edges are exposed to provide a slim bezel appearance, then the aesthetic quality improves, but the edges become vulnerable to damage during folding operations
Solution Approach 1:
The edges of the protective layer are nested within the grooves of the housing decoration. The grooves accommodate the edges in a recessed configuration, protecting them from external impacts and folding stresses while maintaining the slim bezel appearance through precise spatial arrangement.
Solution Approach 2:
The grooves are pre-formed in the housing decoration structure before assembly. This preliminary structural preparation ensures that the protective layer edges are automatically guided and protected during assembly and subsequent folding operations, preventing damage before it occurs.
3Reliability
If the protective layer area is increased beyond the display area, then coverage and protection are improved, but the device complexity and material usage increase
Solution Approach 1:
Instead of uniformly increasing the protective layer area, the solution applies local quality by positioning grooves at specific critical locations where the protective layer edges are most vulnerable during folding. This targeted approach provides enhanced protection where needed without unnecessarily increasing the overall protective layer area or device complexity.

AI summary
An electronic device includes: a display including: a folding area to be folded during a folding operation; and a first area and a second area at opposite sides with respect to a folding area extending in a first direction; a protective layer above the display, and including a first edge located around the first area, and a second edge located around the second area; and a first housing decoration corresponding to the first area and covering an upper surface of the first edge, the first housing decoration having an inner side surface in which a first groove is located. An inner circumferential surface of the first groove includes a first-1 inner circumferential surface facing the upper surface of the first edge, the first-1 inner circumferential surface being upwardly inclined with respect to a direction parallel to the first area, and the first edge is located in the first groove.
