Flexible Display Support Protrusions Prevent Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rollable electronic devices face challenges in maintaining a stable display when bent, as differences in curvature between layers can lead to deformation and lifting, potentially causing damage.
Innovation Solution
A support structure with spaced-apart supporting protrusions is integrated into the housing to surround the flexible display, minimizing contact area and preventing lifting by distributing pressure evenly.

Engineering Contradiction Analysis
1Volume of moving object
If the flexible display is bent to enable rollable device functionality, then the display can be accommodated in a compact state, but differences in curvature between layers cause deformation and lifting of the display
Solution Approach 1:
The support structure is divided into multiple supporting protrusions that are spaced apart from each other on the flexible display surface. This segmentation allows each protrusion to independently support the display at different locations, preventing uniform curvature-induced lifting while maintaining compact accommodation when bent.
Solution Approach 2:
The supporting protrusions are strategically positioned at specific locations on the flexible display rather than providing uniform support across the entire surface. This local quality approach targets specific areas prone to lifting during bending, providing precise support where needed while allowing other areas to conform to the bent shape for compact storage.
2Stability of the object's composition
If a support structure is added to prevent display lifting, then display stability is improved, but device complexity increases
Solution Approach 1:
The supporting protrusions are integrated directly into the housing structure, utilizing the existing housing material and form factor. This self-service approach allows the housing to simultaneously serve as both the device enclosure and the display support mechanism, eliminating the need for separate, complex support components while maintaining display stability.
