Foldable Display Support Structure for Wrinkle-Free Unfolding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display surfaces in foldable electronic apparatuses often fail to maintain flatness when unfolded, resulting in wrinkles at the bending area, which can affect the display quality and user experience.
Innovation Solution
A display apparatus with a foldable display panel, supported by a structure comprising a first and second support and a connection portion with a magnetic field generation system that generates a magnetic field between the supports, allowing the connection portion to be interposed between the display panel and the magnetic field generation portion, which includes a stylus pen insertion space and is designed to reduce wrinkles by applying a force to the bending area when the panel is unfolded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display panel is made foldable to increase display area, then the display surface area is improved, but the flatness of the display surface deteriorates due to wrinkles at the bending area
Solution Approach 1:
A magnetic field generation portion is introduced as an intermediary element between the first and second supports. This magnetic field generation portion includes a magnetic field generation unit that generates a magnetic field to apply a restoring force on the connection portion, thereby mediating the structural integrity and flatness of the display surface during folding and unfolding operations
Solution Approach 2:
The thickness parameter of the connection portion is specifically reduced compared to the first and second supports. This parameter change allows the connection portion to be more flexible and bendable, accommodating the folding motion while the magnetic field restoration mechanism maintains overall flatness
2Shape
If a support structure is added to maintain flatness, then the flatness of the display surface is improved, but the device complexity increases
Solution Approach 1:
The magnetic field generation portion serves multiple functions: it provides structural support between the first and second supports, generates a restoring magnetic field to maintain flatness, and creates a stylus insertion space. This multi-functionality reduces the need for separate components, thereby managing device complexity while achieving the flatness goal
Solution Approach 2:
The magnetic field generation portion is positioned at a specific location between the first and second supports, utilizing the spatial dimension to provide restoration force. The stylus insertion space is also integrated into this spatial arrangement, efficiently using the available dimension without adding excessive structural complexity
