Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design of support structures for curling displays is critical for ensuring reliable curling and unfolding actions, but existing solutions often compromise the stability and ease of assembly.
Innovation Solution
A flexible display apparatus with a two-layer support structure comprising a bendable first support member and a plurality of support bars, along with a tension applying component, to maintain the flat state and enhance curling reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support structure is added to assist curling and unfolding actions, then the reliability of curling display is improved, but the device complexity increases
Solution Approach 1:
The support structure is segmented into multiple support members (first support member, second support member, third support member) that are arranged in sequence. Each support member is independently configured to provide localized support during curling and unfolding, distributing the structural function across multiple components rather than using a single complex support mechanism.
Solution Approach 2:
The support members are arranged in the thickness direction of the flexible display screen, adding a dimensional aspect to the support structure. This vertical arrangement allows the support function to be integrated within the existing display thickness without significantly increasing horizontal complexity.
2Stability of the object's composition
If a support structure is designed to ensure stable curling action, then the stability of curling is improved, but the ease of manufacture decreases
Solution Approach 1:
Different support members are positioned at different locations relative to the flexible display screen and roller shaft. The first support member is adjacent to the screen, the second support member is adjacent to the roller shaft, and the third support member is positioned between them. This localized positioning optimizes the curling stability at each critical point while allowing independent manufacturing and assembly of each support component.
3Adaptability or versatility
If the flexible module moves around the roller shaft to realize unfolding and folding, then the adaptability of display form is improved, but the stress on flexible module increases
Solution Approach 1:
The support members are pre-configured in specific positions and orientations before the flexible module undergoes curling or unfolding. The first support member is positioned to support the screen during initial curling, the second support member is positioned to guide the curling around the roller shaft, and the third support member provides additional support during the unfolding process. This preliminary positioning ensures that support is available at each stage of the transformation, distributing stress evenly throughout the flexible module.

AI summary
Disclosed are a flexible display apparatus and a support assembly. The flexible display apparatus includes: a roller shaft; and a flexible module including a rolling and sliding region and a flat region. The rolling and sliding region moves around the roller shaft. The flexible module includes a flexible display screen and the support assembly. The support assembly is disposed on the side of the surface of the flexible display screen facing the roller shaft, and includes a first support member and a second support member. The second support member is disposed on the side of the first support member facing away from the flexible display screen, and includes a plurality of support bars. The plurality of support bars are arranged along the moving direction of the flexible module, and each support bar is consistent with the extending direction of the roller shaft and is fixed on the first support member.
