Foldable Display Panel Structure With Staggered Support Layer Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable mobile terminals face damage and reduced service life due to stress at bent portions during folding, as the smaller bending radius increases stress on the flexible display panel, leading to potential damage and shorter lifespan.
Innovation Solution
A display apparatus with a folding bracket and flexible display panel where the support layer and panel body are separated, allowing them to move in staggered directions during folding, reducing stress on the panel body by creating a gap between bent portions and enabling a smaller bending radius without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flexible display panel is folded with a small bending radius, then the folded state is more compact, but the stress on the panel body increases leading to damage and reduced service life
Solution Approach 1:
The flexible display panel is divided into two independently movable parts: the panel body and the support layer. During folding, these two parts move in different directions and are separated at the bending position, allowing the panel body to be folded with a small bending radius while the support layer remains relatively stationary, thus avoiding stress concentration and damage to the panel body.
Solution Approach 2:
The support layer is designed to be movable relative to the panel body through the folding mechanism. During the folding process, the support layer dynamically adjusts its position to maintain separation from the panel body at the bending position, enabling the system to achieve both compact folded state and reduced stress on the panel body.
2Reliability
If the support layer and panel body are separated and move in staggered directions, then stress on the panel body is reduced, but the device complexity increases
Solution Approach 1:
The support layer serves multiple functions: it provides structural support to the flexible display panel, acts as a counterbalance during folding movements, and functions as one half of the folding mechanism itself. By making the support layer movable and separating it from the panel body, the same component achieves both support and active participation in the folding motion, reducing the need for additional complex mechanisms.
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 staggered movement of the support layer and panel body reduces stress on the panel body during folding, prolonging the service life and allowing for a smaller, more compact folded state without compromising durability.
Implementation Method 1
The first swing member and the second swing member are rotatably connected to the base separately
Implementation Method 2
The first swing member and the second swing member are slidably connected to each other; the first swing member is movable in a direction towards or away from the base relative to the second swing member
