Display Panel Support Frame Linkage for Stress Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable screens face stress and strain issues due to the connection to middle frames during bending and unbending, leading to potential damage, as existing solutions using springs are prone to failure and have inconsistent elastic coefficients.
Innovation Solution
A display panel support frame with a connecting member comprising a first fixed shaft, a second fixed shaft, a rotation shaft, and connecting links that allow the support plate to slidably connect to the third support frame, reducing tensile or compression stress through relative displacement and damping, thereby protecting the flexible screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If springs are used to enable relative displacement between support plate and middle frame, then the flexibility and stress absorption are improved, but the reliability and durability deteriorate due to spring failure and inconsistent elastic coefficients
Solution Approach 1:
The patent introduces a connecting member as an intermediary component between the support plate and middle frame. This connecting member includes a linking member with multiple links (first link, second link, third link) and fixed shafts that mediate the relative displacement, replacing the direct spring connection and providing more reliable stress absorption through a mechanical linkage system.
Solution Approach 2:
The connecting member is segmented into multiple independent links (first link, second link, third link) connected by fixed shafts. This segmentation allows each link to independently absorb stress and accommodate displacement, improving both flexibility and reliability compared to a single spring component.
2Stability of the object's composition
If a rigid connection is used between support plate and middle frame, then the structural stability is improved, but the stress and strain on the flexible display screen increase during bending and unbending
Solution Approach 1:
The patent transforms the rigid static connection into a dynamic mechanism. The connecting member with its multiple links and fixed shafts enables dynamic relative displacement between the support plate and middle frame during bending and unbending, allowing the structure to adapt to changing geometric conditions while maintaining stability and reducing stress on the display screen.
Solution Approach 2:
The connecting member acts as an intermediary mechanism that decouples the rigid connection between support plate and middle frame. It mediates the relative motion and stress distribution, allowing the support plate to move relative to the middle frame through a controlled mechanical linkage rather than direct rigid contact.
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 reduces stress and strain on the non-bending area of the screen, preventing damage by allowing the support plate and third support frame to move relative to each other, generating a damping effect that prevents excessive tensile or compressive stress during folding and unfolding.
Implementation Method 1
a rotation shaft rotated around the first fixed shaft
Implementation Method 2
the damping produced by the linking member will protect the display screen
Implementation Method 3
the rotation shaft, the first connecting link, and the second connecting link are configured to move in the slide rail

AI summary
A display panel support frame and a display panel are provided. The display panel support frame includes a first support frame, a second support frame, a third support frame, and a plurality of connecting members. The support plate on the first support frame and the second support frame may be relatively displaced from the third support frame through the connecting member of a linking member, thereby reducing the tensile or compressive stress of the non-bending area of the screen.
