Flexible Display Roller Mechanism for Dynamic Screen Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to adjust the screen size appropriately for the quantity and type of information being displayed, leading to inconvenience for users when the screen size is either too large or too small for the content.
Innovation Solution
A display device with a flexible display that can be wound or unwound from a roller, controlled by a controller to change screen sizes based on the quantity of information, and capable of executing multiple modes for displaying different quantities of information effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display is expanded to a fixed large size, then the screen area is increased for displaying more information, but the screen size becomes inappropriate when less information needs to be displayed
Solution Approach 1:
The display device transitions from a fixed-size display to a dynamically adjustable display that can change its size based on the amount of information to be displayed. The roller mechanism allows the flexible display to be wound or unwound, creating variable screen sizes that adapt to different content requirements, thus resolving the contradiction between having a large screen area and maintaining screen size adaptability.
Solution Approach 2:
The display size parameter is made variable through the roller winding mechanism. By changing the winding state of the roller, the effective display area parameter is adjusted to match the information quantity, allowing the system to optimize between maximizing screen area and adapting screen size to content needs.
2Quantity of substance
If the display is projected greater than required size, then more information can be displayed, but user convenience deteriorates due to inappropriate screen size
Solution Approach 1:
The system dynamically adjusts the display size to match the information quantity being presented. Rather than always projecting the maximum display area, the roller mechanism enables real-time size adjustment so that the screen area corresponds appropriately to the content volume, maintaining user convenience while displaying the required information quantity.
Solution Approach 2:
The controller receives information about the quantity of content to be displayed and uses this feedback to determine the appropriate screen size. This feedback mechanism ensures that the display size is optimized for each specific content scenario, preventing both oversized displays for small content and undersized displays for large content, thereby maintaining user convenience across different usage scenarios.
3Volume of moving object
If the display is projected smaller than required size, then the device structure becomes more compact, but the screen area becomes insufficient for displaying all information
Solution Approach 1:
The flexible display is nested within the device body when not in use or when displaying minimal content. The roller mechanism allows the display to be wound compactly inside the device housing, achieving a compact device volume. When more screen area is needed, the display can be unwound and projected outward, providing sufficient display area while maintaining a compact form factor when the full display area is not required.

AI summary
A display device includes a body; a roller rotatably installed in the body; a flexible display configured to be wound or unwound from the roller in response to a rotation of the roller; and a controller configured to detect a type of a content to be displayed, and change a screen size of the flexible display according to the detected type of the content by winding or unwinding of the flexible display.
