Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices face challenges in reducing manufacturing costs, improving flexibility, and minimizing defect rates while maintaining a simplified structure.
Innovation Solution
A flexible display device design incorporating a back cover with a mesh structure composed of high and low rigidity materials, where high rigidity members intersect with low rigidity members to form a mesh pattern, supporting the display panel and reducing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a back cover with mesh structure composed of first members and second members of different materials is used, then flexibility and anisotropic properties are improved, but device complexity increases
Solution Approach 1:
The back cover is segmented into multiple first members extending in a first direction and multiple second members extending in a second direction, forming a mesh structure. This segmentation allows each member to be optimized independently for flexibility while maintaining overall structural integrity, resolving the contradiction between flexibility and complexity.
Solution Approach 2:
Different regions of the back cover have different material properties - first members are made of one material and second members are made of a different material. This local quality variation enables anisotropic flexibility where the back cover can bend differently in different directions, improving adaptability while keeping the design systematic rather than chaotic.
2Ease of manufacture
If a back cover with mesh structure is used, then manufacturing cost is reduced, but manufacturing precision may be affected
Solution Approach 1:
The mesh structure divides the back cover into discrete first members and second members that can be manufactured separately using cost-effective processes, then assembled together. This segmentation reduces manufacturing cost while the defined geometric relationships between members maintain sufficient precision for the application.
Solution Approach 2:
The first members and second members are combined to form an integrated mesh structure that provides both cost benefits from simplified manufacturing and functional benefits from the combined structural elements, achieving a balance between manufacturing ease and precision requirements.

AI summary
A flexible display device may include a flexible display panel, and a back cover at a rear surface of the flexible display panel and supporting the flexible display panel. The back cover may include a plurality of first members extending in a first direction, and a plurality of second members extending in a second direction and intersecting the plurality of first members. The plurality of second members may include a different material from the plurality of first members.
