Flexible Display Assembly With Arc-Shaped Edge Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible displays face issues with edge separation from supporting members due to elastic deformation, leading to poor fixation and reduced screen-to-body ratio when bent or folded.
Innovation Solution
A display assembly comprising a flexible display, a flexible cover plate, and a supporting member, where the flexible display's edge has an arc-shaped extending part covered by a matching arc-shaped part of the flexible cover plate, and the rigid cover plate covers both the flexible cover plate and the supporting member, counteracting elastic forces to prevent detachment and increase screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid cover plate is used to fix the flexible display edge to the supporting member, then fixation reliability is improved, but the device complexity increases and the screen-to-body ratio decreases
Solution Approach 1:
The cover plate is divided into two functional segments: a flexible cover plate portion that conforms to the bent display edge, and a rigid cover plate portion that provides structural support and fixation. This segmentation allows each part to perform its specific function optimally without requiring a completely rigid structure, thus improving fixation reliability while controlling device complexity.
Solution Approach 2:
Different portions of the cover plate have different mechanical properties: the first extending part (covering the flexible display edge) is made flexible to match the bent shape, while the second extending part (covering the supporting member) is made rigid for stable fixation. This local differentiation of material properties resolves the contradiction between flexibility needed for conforming and rigidity needed for secure attachment.
2Shape
If the flexible display is bent to achieve arc-shaped display, then screen-to-body ratio is improved, but the flexible display elastically deforms causing edge separation from the supporting member
Solution Approach 1:
The rigid cover plate portion is designed to counteract the elastic deformation forces generated when the flexible display is bent. By providing preliminary structural support and constraint, the rigid portion prevents the bent edge from separating from the supporting member, thus resolving the fixation stability issue while maintaining the desired arc-shaped display.
Solution Approach 2:
The cover plate employs a composite structure combining flexible and rigid materials in one component. This composite design allows the cover plate to both conform to the bent display shape and provide the structural support needed to prevent separation, simultaneously achieving arc-shaped display and fixation stability.
3Stability of the object's composition
If a planar flexible cover plate is used, then the flexible display remains in planar unfolded state without internal stress, but the screen-to-body ratio becomes relatively small
Solution Approach 1:
The flexible cover plate portion is designed to be dynamic and adaptable, capable of conforming to various shapes (planar or arc-shaped) depending on the display state. This dynamic flexibility allows the system to maintain planar stability when needed while achieving high screen-to-body ratio through arc-shaped configurations when desired.
