Parallel Rotation Support for Foldable Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies, particularly OLED displays, require a flexible and foldable support apparatus to accommodate the next generation of bendable or foldable display panels, which existing solutions fail to adequately support in terms of rotation and distance maintenance between rotation shafts.
Innovation Solution
The apparatus includes first and second support portions with connecting portions and a link member, allowing for rotation based on parallel rotation shafts while maintaining a constant distance, with stoppers and magnetic members to control angles and prevent over-rotation, enabling the display panel to be bendable or foldable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible and foldable support apparatus is used to accommodate bendable or foldable display panels, then the adaptability and versatility of the display device is improved, but the device complexity increases due to the need for rotation mechanisms and distance maintenance structures
Solution Approach 1:
The support apparatus is divided into multiple independent components: first and second support portions, connecting portions with rotation shafts, spacers, and link members. Each component performs a specific function (supporting, rotating, maintaining distance, connecting), which simplifies the overall design while achieving the required flexibility and foldability for the display device.
2Ease of operation
If rotation mechanisms with parallel rotation shafts are implemented to enable folding, then the ease of operation is improved, but the manufacturing precision requirements increase to maintain constant distance between rotation shafts
Solution Approach 1:
A spacer is introduced as an intermediary component between the first and second connecting portions. The spacer maintains a constant distance between the parallel rotation shafts and allows the connecting portions to rotate freely. This intermediary structure simplifies the manufacturing process by providing a ready-made distance reference, reducing the precision requirements for directly machining the rotation shaft positions.
3Reliability
If stoppers and magnetic members are added to control rotation angles, then the reliability of the folding mechanism is improved, but the device complexity increases
Solution Approach 1:
The stoppers and magnetic members are designed to automatically control the rotation angles without requiring external control systems. The magnetic members provide automatic alignment and positioning forces, while the stoppers mechanically limit the rotation range. This self-service mechanism improves reliability by ensuring consistent rotation control while minimizing added complexity, as the components work passively based on their physical and magnetic properties.

AI summary
An apparatus for supporting a display panel is disclosed. In one aspect, the apparatus includes first and second support portions configured to support a display panel and respectively rotatable based on first and second rotation axes substantially parallel to each other. The apparatus also includes a first connecting portion positioned on the first rotation shaft and fixedly combined to one side of the first support portion and a second connecting portion positioned on the second rotation shaft and fixedly combined to one side of the second support portion. The apparatus further includes a spacer maintaining a constant distance between the first and second rotation axes, wherein the spacer is penetrated by the first and second connecting portions such that the first and second connecting portions are rotatable and a link member rotatably combined to one side of the first connecting portion and one side of the second connecting portion.
