Flexible Display Rolling Mechanism for Adaptive Screen Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible display technologies are limited in their ability to dynamically adjust screen size based on content, primarily designed for portable use and do not effectively accommodate larger sizes or user interactions with household devices, restricting their functionality and user experience.
Innovation Solution
A display apparatus comprising a flexible display, a driver, and a processor that adjusts the screen size by rolling the display area, allowing the screen size to change in response to content requirements, user interactions, and external events, enabling adaptive display ratios and sizes for various applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display is folded or rolled to change screen size, then the display can be moved or stored, but the screen size cannot be adaptively adjusted for different content formats
Solution Approach 1:
The patent implements dynamic screen size adjustment by allowing the flexible display to transition between unfolded and rolled states based on content requirements. The display can be partially rolled to achieve intermediate sizes, enabling adaptive formatting for different content types while maintaining operational simplicity through automated control.
Solution Approach 2:
The system changes the physical parameter of screen size by controlling the rolling mechanism. The processor determines the appropriate screen size based on content format and automatically adjusts the display's rolled state, transforming the display from a static size device to one with dynamically adjustable parameters.
2Adaptability or versatility
If a flexible display is designed for portable use only, then it can be carried around, but it cannot effectively function as a large household device
Solution Approach 1:
The flexible display employs dynamic size adjustment capability, transitioning between compact rolled states for portability and expanded unfolded states for large-screen household applications. This dynamic characteristic allows the same display to serve multiple size requirements without compromising either portable convenience or large-screen functionality.
3Productivity
If the screen size is fixed, then the display structure is simple, but the content display efficiency is reduced due to image distortion or unused space
Solution Approach 1:
The display system dynamically adjusts screen size to match content dimensions, eliminating both image distortion and unused display space. The processor analyzes content format and automatically configures the display's rolled state to achieve optimal aspect ratio matching, thereby maximizing content display efficiency without manual intervention.
4Area of stationary object
If the flexible display is fully unfolded, then the screen size is maximized, but it cannot be compacted for storage or transport
Solution Approach 1:
The flexible display implements a nesting configuration where the display can be rolled into a compact form factor for storage or transport, similar to a nested structure. When not in use or when portability is required, the display is rolled into a small package, and when needed, it is unrolled to achieve full screen area, effectively nesting the large screen within a small form factor.

AI summary
A display apparatus is provided. The display apparatus includes a flexible display configured to display an image, a driver configured to change a screen size of the flexible display, and a processor configured to control the driver to display an image corresponding to a content, at a screen size corresponding to a size of a content to be displayed in the flexible display.
