Dual Touch Screen Mobile Terminal with Dynamic Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with touch screens face challenges in efficiently displaying and managing multiple information items, particularly in transitioning between single and dual-touch screen states, which affects user convenience and functionality.
Innovation Solution
A mobile terminal with dual-displays and a controller that activates/deactivates touch screens based on folding states, allowing the item list and information to be seamlessly transferred between screens, enabling enhanced user interaction and functionality through proximity and contact touches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single touch screen is used to display multiple information items, then the device structure remains simple, but the user interface becomes cluttered and information visibility is reduced
Solution Approach 1:
The display area is segmented into multiple independent touch screens (first touch screen and second touch screen), allowing different information items to be displayed simultaneously on separate screens. This segmentation resolves the contradiction by providing sufficient display space for multiple information items while maintaining a relatively simple overall device structure through modular screen configuration.
Solution Approach 2:
The patent transitions from a single two-dimensional display to a multi-dimensional display arrangement where multiple touch screens are positioned at different spatial locations and orientations. This dimensional expansion allows users to view multiple information items simultaneously without crowding, effectively resolving the information visibility issue while keeping each individual screen simple.
2Loss of information
If multiple touch screens are activated simultaneously, then information visibility and user interaction improve, but the energy consumption and device complexity increase
Solution Approach 1:
The system dynamically activates or deactivates the second touch screen based on user interaction states. When a first information item is selected on the first touch screen, the second touch screen is activated to display related second information items. This dynamic activation ensures that multiple screens are only active when needed, improving information visibility while avoiding continuous energy consumption from having all screens permanently active.
Solution Approach 2:
The touch screens are activated periodically or on-demand based on user selection events rather than continuously. The controller activates the second touch screen only when triggered by a selection event on the first touch screen, creating a periodic activation pattern that balances information visibility requirements with energy conservation.
3Adaptability or versatility
If information items are displayed in a crowded layout on a single screen, then all information is accessible, but user interaction becomes difficult and input manipulation is reduced
Solution Approach 1:
By dividing the display into multiple touch screens, each screen can present information in a less crowded, more manageable layout. Users can access multiple information items across different screens without the clutter and interaction difficulties that would result from displaying all items on a single crowded screen.
Solution Approach 2:
The patent utilizes spatial separation across multiple touch screens positioned in different dimensions and orientations. This allows users to access diverse information items by interacting with different screens rather than navigating through a crowded single-screen interface, significantly improving ease of operation and input manipulation while maintaining comprehensive information accessibility.

AI summary
A mobile terminal and method for displaying information in the mobile terminal may be provided that includes first and second touch screens, and a controller to display both an item list including a plurality of information items and first information related to a first information item selected from the item list on the first touch screen. The controller may display one of the item list and the first information on the second touch screen when the second touch screen is activated based on manipulation of the mobile terminal. The controller may display second information associated with a second information item on the touch screen on which the first information is already displayed as the second information item is selected from the item list in a state that the first information item is selected.
