Scrollable Flexible Display With Magnetic Back Support Flatness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scroll type display devices face issues with the lack of adequate support at the middle of flexible display screens, leading to non-flatness and wider frames due to side support structures.
Innovation Solution
A scroll type display device with magnetic support structures on the rear surface of the flexible display screen and a buffer layer system, allowing the screen to be wound and extended without side support, using a drive mechanism to rotate the scroll shafts and buffer layer shafts for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If side support structures are used for the flexible display screen, then the screen has adequate support, but the frame width increases and the screen lacks flatness in the middle
Solution Approach 1:
The support structure is moved from the side (horizontal dimension) to the middle of the screen (vertical dimension). Multiple support structures are arranged along the vertical direction of the flexible display screen, providing support in the middle area rather than at the sides, thus reducing frame width while maintaining support stability
Solution Approach 2:
The support structure is divided into multiple discrete support elements (support films with support columns) arranged vertically along the flexible display screen. These segmented support structures provide distributed support across the screen middle area, improving both support stability and allowing for narrower frames
2Stability of the object's composition
If side support structures are used for the flexible display screen, then the screen has adequate support, but the flatness of the screen deteriorates
Solution Approach 1:
Support is provided from the rear surface side (vertical dimension) rather than from the sides (horizontal dimension). The support structures extend from the rear surface toward the front surface of the flexible display screen, providing upward support in the middle area to maintain screen flatness
Solution Approach 2:
Support is concentrated in the middle area of the flexible display screen where it is most needed for maintaining flatness. The support structures are strategically positioned in the central region rather than distributed uniformly or at the edges, providing localized support that effectively maintains screen shape
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
