Flexible Display Panel Correction Roller for Flat Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices face issues with structural rigidity, leading to drooping, twisting, and bending, which affect their stability and functionality.
Innovation Solution
A display device design incorporating a flexible display panel with a panel roller, pipes, guide rollers, and correction units to maintain structural rigidity, including a correction roller and roll plate to ensure the display remains flat during unwinding and winding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display panel is used to enable winding and unwinding, then adaptability and versatility are improved, but structural rigidity deteriorates causing drooping and twisting
Solution Approach 1:
The patent introduces a rigid support structure comprising multiple pipes (first pipe, second pipe, third pipe) and guide rollers as intermediary elements between the flexible display panel and the external environment. These components maintain the display panel's flatness during winding and unwinding operations, preventing drooping and twisting while preserving flexibility functionality.
Solution Approach 2:
The patent adds spatial dimensionality to the support system by arranging pipes and guide rollers in specific three-dimensional configurations. The first and second pipes are positioned opposite each other with the panel roller between them, while the third pipe extends between the first and second pipes, creating a multi-dimensional support framework that constrains the flexible display panel in space.
2Stability of the object's composition
If support structures are added to prevent drooping and twisting, then structural rigidity is improved, but device complexity increases
Solution Approach 1:
The support structure is segmented into distinct functional components: first pipe, second pipe, third pipe, guide roller, and correction unit. Each segment performs a specific function in maintaining display panel stability, allowing for modular design and assembly while distributing the structural support function across multiple specialized elements.
Solution Approach 2:
The pipes and guide rollers serve multiple functions simultaneously: they provide structural support to prevent drooping, guide the display panel during winding/unwinding, maintain flatness, and prevent twisting. This multi-functionality reduces the need for separate components for each function, thereby managing complexity.

AI summary
A display device is disclosed. The display device includes a flexible display panel, a panel roller extending long, the display panel being wound around or unwound from the panel roller, a first pipe located adjacent to the panel roller, a second pipe opposite the first pipe with respect to the panel roller, a third pipe located adjacent to the panel roller between the first pipe and the second pipe, a guide roller opposite the third pipe with respect to the panel roller, and a correction unit installed at the first pipe, the correction unit having a correction roller, into which the first pipe is inserted, and a roll plate extending long, the roll plate being curved in a direction intersecting a longitudinal direction in which the roll plate is wound around or unwound from the correction roller.
