Foldable Display Holding Structure with Elastic Supporting Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices experience deformation and poor visual effects when transitioning from a folded to a spread state due to unsupported bending areas of the flexible display panel, leading to a suspended and unflat display.
Innovation Solution
A holding structure with a housing, supporting stages, a supporting element, and flexible elements that pivotally connect, allowing the supporting element to fill the gap between stages using elastic force, ensuring the display panel is held flat and preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flexible display panel is folded to create a compact device, then the device portability is improved, but the display panel deformation and visual quality deteriorate when spread
Solution Approach 1:
The housing is divided into multiple portions (first portion, second portion, third portion) that can pivot relative to each other, allowing the device to be segmented for folding while maintaining support structures in each segment to preserve display flatness when spread
Solution Approach 2:
A supporting element is introduced as an intermediary component between the housing portions and the flexible display panel. This supporting element actively fills the gap between supporting stages and provides continuous support to the bending area, preventing deformation while allowing the housing to fold
2Adaptability or versatility
If the housing portions are pivotally connected to enable folding, then the device adaptability is improved, but the display panel support stability deteriorates in spread state
Solution Approach 1:
The supporting element is designed to be dynamically adjustable rather than fixed. It can move to fill the gap between supporting stages when needed and retract when not needed, adapting to the device's folding and spreading states while maintaining display stability
Solution Approach 2:
The supporting element proactively counteracts the potential deformation of the flexible display panel by filling the gap between supporting stages before the panel can sag or deform, preventing the instability issue rather than correcting it afterward
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively maintains the flexible display panel flat in a spread state, enhancing the user's visual experience by providing necessary support and preventing bending area suspension, thus improving usability and visual clarity.
Implementation Method 1
Two ends of the first flexible element are respectively connected to the supporting element and the third portion of the housing... the supporting element may be moved toward the gap between the first and second supporting stages by the elastic force of the first flexible element

AI summary
A foldable display device includes a holding structure and a flexible display panel. The holding structure includes a housing, a first supporting stage, a second supporting stage, a supporting element, and a first flexible element. A third portion of the housing is pivotally connected to a first portion and a second portion of the housing. The third portion of the housing has an accommodating space. The first supporting stage is located on the first portion of the housing. The second supporting stage is located on the second portion of the housing. A gap is formed between the portion of the second supporting stage and the portion of the first supporting stage. The supporting element is located in the accommodating space. Two ends of the first flexible element are respectively connected to the supporting element and the third portion of the housing.
