Flexible Display Fixing Rod for Screen Deformation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display screens deform when unwound or unfolded, leading to a poor visual experience due to their storage state, which is typically wound or folded, resulting in an irregular display area.
Innovation Solution
A flexible display device with a fixing rod connected to the screen through a rotating device, allowing the rod to parallel the screen's expansion direction and detachably connect to its end, stabilizing the screen in an expanded state to prevent curling and deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flexible display screen is stored in a wound state or folded state to reduce volume, then the volume of the portable display device is reduced, but the area for displaying images deforms after the flexible display screen is unwound or unfolded
Solution Approach 1:
The fixing device divides the flexible screen into two parts: the fixed first end and the movable second end. This segmentation allows the first end to remain stable while the second end can be positioned freely, preventing deformation of the display area while maintaining volume reduction capability.
Solution Approach 2:
The first end of the flexible screen is fixed in advance to the housing before use. This preliminary fixing action ensures that when the screen is unwound or unfolded, the display area maintains its shape without deformation, as one end is already secured in position.
2Area of stationary object
If the flexible display screen is unwound or unfolded to display images in a larger area, then the display area is increased, but the flexible display screen deforms due to storage state
Solution Approach 1:
By segmenting the screen into a fixed first end and a movable second end, the invention allows the display area to be fully unwound for large-area display while the fixed first end provides stability. This prevents the entire screen from deforming while maintaining the ability to expand the display area.
Solution Approach 2:
The housing acts as an intermediary between the flexible screen and the external environment. It provides a stable mounting point for the first end of the screen, allowing the screen to be unwound to full extent while preventing deformation through the stabilizing presence of the housing structure.
3Volume of moving object
If the flexible display screen is stored in a wound state, then the volume is reduced, but the display area deforms after unwinding
Solution Approach 1:
The first end of the flexible screen is preliminarily fixed to the housing during assembly, before the screen is wound or unfolded. This preliminary fixing ensures that when the screen is later unwound for display, the display area maintains its regularity and does not deform, while still allowing compact storage when not in use.
Solution Approach 2:
Segmenting the screen into a fixed portion (first end) and a movable portion (second end) allows the fixed portion to maintain display area regularity while the movable portion can be wound or unwound. This segmentation resolves the contradiction between compact storage and display area regularity.

AI summary
Provided is a flexible display device. The flexible display device includes a flexible screen and a fixing rod. The fixing rod is connected to the flexible screen through a rotating device. The fixing rod has a first end and a second end. The fixing rod is capable of rotating to such position that the fixing rod is parallel to an expansion direction of the flexible screen and the second end of the fixing rod is detachably connected to the flexible screen. With the rotating device, the fixing rod of the flexible display device can be switched between a fixing state and a non-fixing state. In the fixing state, the flexible screen is fixed by the fixing rod to prevent deforming of the flexible screen.
