Foldable Display Support Member Groove Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable display devices require additional structures to cover their edges, which complicates manufacturing, increases costs, and can lead to aesthetic issues and line defects during assembly.
Innovation Solution
A foldable display device design that incorporates a display panel with a foldable area and non-folding areas, featuring a support member with stretchable parts and cutting parts including grooves of varying depths to eliminate the need for edge coverings, improving attachment accuracy and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional structures are used to cover the edges of the display panel, then the structural integrity is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The support member is designed to perform multiple functions simultaneously: it provides structural support to the display panel while its edges are directly exposed without requiring separate edge covering structures. The cutting parts (grooves) are integrated into the support member itself, eliminating the need for additional edge protection components and simplifying the overall device structure.
2Strength
If additional structures are used to cover the edges of the display panel, then the structural integrity is improved, but the manufacturing cost increases
Solution Approach 1:
By integrating the edge exposure function directly into the support member design, the patent eliminates the need for separate edge covering components. This reduction in part count simplifies the manufacturing process and reduces assembly steps, thereby lowering production costs while maintaining the necessary structural support.
3Strength
If additional structures are used to cover the edges of the display panel, then the structural integrity is improved, but line defects occur during assembly
Solution Approach 1:
The patent removes the edge covering structures entirely, exposing the edges of the display panel directly through the cutting parts of the support member. This extraction of unnecessary components eliminates the potential for line defects that would otherwise occur during the assembly of multiple parts, while the support member itself maintains the required structural integrity.
4Strength
If additional structures are used to cover the edges of the display panel, then the structural integrity is improved, but aesthetic issues arise
Solution Approach 1:
The support member is designed with cutting parts that directly expose the display panel edges, creating a clean and simple aesthetic appearance. By merging the support function with the edge exposure design, the patent eliminates the visual complications and aesthetic issues that would arise from additional edge covering structures, while maintaining structural integrity through the properly designed support member.

AI summary
A display device includes a display panel including a display area including a foldable area having flexibility and a non-folding area adjacent to at least one side of the foldable area and a support member disposed under the display panel, including a stretchable part overlapping the foldable area, and defining at least one cutting part. The at least one cutting part includes at least one first groove having a first depth and a second groove having a second depth greater than the first depth.
