Rollable Mobile Terminal With Dynamic Display Region Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals have fixed display sizes, making them inconvenient to carry and use, as they lack flexibility in functionality and user interface adjustment.
Innovation Solution
A rollable mobile terminal with a touch screen that can be adjusted by moving two bodies, allowing different display regions to be exposed or hidden, and a controller that manages screen information and user access based on these movements, enabling various functions and user interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed size display is used in mobile terminals, then the display structure is simple and stable, but the terminal is inconvenient to carry and lacks flexibility in functionality
Solution Approach 1:
The display structure transitions from a fixed static configuration to a dynamic rollable configuration. The touch screen can be rolled out to expand the display area or rolled in to reduce the terminal size, allowing the display to adapt its state based on usage requirements while maintaining structural integrity through the guide unit mechanism
2Ease of operation
If the display region is changed by moving bodies, then the user interface flexibility is improved, but the control complexity increases
Solution Approach 1:
The controller automatically detects the position state of the movable body and autonomously determines which region of the touch screen is exposed, then automatically sets the display region and adjusts screen information accordingly. This self-service control mechanism eliminates the need for complex manual control interfaces while maintaining ease of operation

AI summary
The present invention relates to a rollable mobile terminal having a rollable display, the rollable mobile terminal comprising: a touch screen formed to be rollable; a first body connected to one end of the touch screen; a second body connected to the other end opposite to the one end of the touch screen; a guide unit which is arranged at the first body and/or the second body, and is formed to wrap around the touch screen so as to accommodate thereof; and a control unit for setting at least a part of the touch screen, which is exposed to the outside of the guide unit by a movement, as a display region when the first body and/or the second body are moved by an external force, and outputting screen information to the display region, wherein the control unit outputs different pieces of the screen information to the display region on the basis of the body, which is moved by the external force, between the first body and the second body.
