Rollable Mobile Terminal Dynamic Display Region Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals with fixed-sized displays are inconvenient for carrying and require new user interface solutions due to their inflexible screen sizes, especially with the advent of rollable display technologies that allow for adjustable screen regions.
Innovation Solution
A rollable mobile terminal with a touch screen that can be wound and unwound, featuring a controller to set display regions and display virtual home buttons corresponding to multiple windows, allowing users to control each window independently through touch inputs and adjust the layout based on the screen size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size display is used in conventional mobile terminals, then the device structure is simple and easy to manufacture, but the terminal is inconvenient to carry and lacks flexibility in display region adjustment
Solution Approach 1:
The display region is made dynamic and adjustable through a sensing unit that detects the position of a movable body, allowing the display area to change from a fixed state to a variable state. This enables the terminal to adapt to different usage scenarios while maintaining a relatively simple overall structure.
2Adaptability or versatility
If a single home button is used to control a single screen, then the control interface is simple, but it cannot accommodate multiple windows with different screen information in rollable displays
Solution Approach 1:
The single home button is segmented into multiple virtual home buttons, with each virtual button corresponding to a specific window. This segmentation allows independent control of multiple windows while maintaining the simplicity of button-based interaction, resolving the contradiction between multi-window capability and interface complexity.
Solution Approach 2:
Multiple virtual home buttons are created as software copies of the traditional home button concept. Each virtual button replicates the home function for its associated window, enabling multi-window control without introducing entirely new control mechanisms.
3Area of moving object
If the display region is extended to show more content, then the information display capability is improved, but the portability and ease of carrying is reduced
Solution Approach 1:
The display area is made dynamically adjustable rather than fixed. Users can extend the display region when more information is needed and retract it when portability is prioritized. This dynamic adjustment resolves the contradiction by allowing the display area to adapt to different operational requirements.

AI summary
The present invention relates to a rollable mobile terminal having a rollable touch screen and a control method therefor. The rollable mobile terminal comprises: a touch screen formed to be rollable; a first body connected to one end of the touch screen and configured to receive the touch screen therein while winding the same; a second body connected to an opposite end of the touch screen; and a control unit that sets at least one area of the touch screen exposed from the first body to the outside as a display area and outputs, on the display area, multiple virtual home buttons corresponding to multiple windows including different screen information when the multiple windows are output on the display area.
