Foldable Touchscreen Dynamic Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices do not maximize screen usage when folded, as only the facing screen is active, leaving the back and side screens turned off, which limits functionality and user experience.
Innovation Solution
A screen display control method for foldable touchscreens that allows the electronic device to dynamically switch between displaying content on the primary screen and the secondary screen based on user interactions, enabling cooperative work between the two areas and optimizing screen utilization by turning on the secondary screen when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the foldable screen is folded to reduce space occupation, then portability is improved, but screen utilization deteriorates because only the facing screen is active
Solution Approach 1:
The touchscreen is divided into a first area (facing screen) and a second area (back and side screens). When folded, the first area displays the primary interface while the second area can be independently activated to display additional content or interfaces, allowing both screen segments to contribute to functionality even in folded state
Solution Approach 2:
The system dynamically switches between different display modes based on user interaction. When a user performs a first operation on the first interface, the system transitions from displaying only on the first area to activating the second area for cooperative display, and can switch back when a second operation is detected
2Use of energy by moving object
If only the facing screen is turned on when folded, then power consumption is reduced, but functionality deteriorates due to limited screen usage
Solution Approach 1:
Instead of turning on the entire second area, the system activates only the specific portion of the second area that is needed for the associated content. This partial activation approach provides enhanced functionality while minimizing additional power consumption compared to full-screen activation

AI summary
A screen display control method may be implemented by an electronic device configured with a foldable touchscreen. The touchscreen includes a first area and a second area. A first interface is displayed in a first area and a first operation is detected in a first interface. A second interface is displayed in a second area in response to the first operation and the second interface is associated with content displayed in the first interface.
