Foldable Display Panel Magnetic Attachment to Jig
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices face detachment issues of the flexible display panel from the supporting jig due to repeated folding, which compromises the device's structural integrity and functionality.
Innovation Solution
A foldable display device design incorporating a metal plate on the display panel, a magnetic member between the metal plate and the jig, and an adhesive member to securely fasten the display panel to the jig, utilizing a nickel-iron alloy or stainless steel for the metal plate and a permanent or electromagnet as the magnetic member, along with a guide ring for additional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display panel is repeatedly folded, then the foldable display device can be carried easily and realized as a large-size display screen, but the folding portion of the display panel may be deformed causing detachment from the jig
Solution Approach 1:
A magnetic member is disposed between the display panel and the jig before folding operations begin, establishing a preliminary magnetic connection that prevents deformation and detachment during subsequent folding and unfolding cycles
Solution Approach 2:
A magnetic member is introduced as an intermediary element between the display panel and the jig, using magnetic force to maintain their connection during repeated folding operations without interfering with the folding mechanism
