Magnetic Planarization Member for Foldable Display Step Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices often experience a step formation between metal plates due to assembly tolerance and folding, leading to visible bending deformation around the folding axis, which affects the display's flatness and user experience.
Innovation Solution
Incorporating a magnetic planarization member that maintains the surfaces of the first and second support members on the same reference surface, reducing the occurrence of steps between these members and ensuring a flat display when folded or unfolded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two metal plates are attached to a display module to enable folding, then the display device can be folded or unfolded to provide a larger screen, but a step occurs between the two metal plates due to assembly tolerance, causing visible bending deformation
Solution Approach 1:
A planarization member is introduced as an intermediary component between the first and second support members. This planarization member includes a first contact portion contacting the first support member and a second contact portion contacting the second support member, thereby mediating the interface between the two support members to maintain their surfaces on the same reference plane and eliminate steps caused by assembly tolerances
Solution Approach 2:
The planarization member extends in a first direction to connect the first and second support members, adding a dimensional element that spans across the gap between the support members. This extended structure provides a planarizing effect across the interface, ensuring both support members' surfaces align on the same reference plane
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 magnetic planarization member effectively minimizes step formation between the support members, maintaining the display's flatness and enhancing the user experience by preventing visible bending deformations and ensuring a smooth folding mechanism.

AI summary
A display device includes a display module, a first support member and a second support member disposed below the display module and separated from each other, wherein the first support member and second support member are disposed with respect to a folding axis; and a planarization member disposed on one side of the first support member and that maintains one surface of the first support member and one surface of the second support member on a same reference surface.
