Dynamic Touch Display Area Configuration for Multi-Screen Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with multiple touch screens are controlled separately, limiting user interaction as the application interface is only displayed on one screen.
Innovation Solution
A control method that obtains screen change information and configures a touch display area of the electronic device to respond to target touch operations, allowing the touch display area to be adjusted based on screen changes, such as size, pose, or resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple touch screens are connected separately, then each screen can be controlled independently, but the application interface is limited to one screen and user interaction is restricted
Solution Approach 1:
The patent merges multiple separate touch screens into a unified control system where a single application interface can span across multiple screens. The touch controller integrates touch events from all screens and the processor coordinates them as a unified display area, allowing users to interact with applications across the entire multi-screen surface rather than being confined to individual screens.
Solution Approach 2:
The patent makes the multi-screen system universal by enabling any screen to display any part of the application interface based on screen configuration changes. The system adapts to different screen arrangements (folded, unfolded, rotated) and dynamically adjusts the application interface distribution, making the interface display capability versatile across various screen states and configurations.
2Adaptability or versatility
If the touch display area is fixed, then the control system is simple, but it cannot respond to screen configuration changes such as size, pose, or resolution
Solution Approach 1:
The patent implements a dynamic touch display area configuration where the system automatically adjusts the touch-sensitive regions based on real-time screen configuration changes. When screens are folded, unfolded, or rotated, the touch controller and processor dynamically recalculate and reconfigure which display areas respond to touch operations, allowing the system to adapt to various screen states without manual intervention.
Solution Approach 2:
The system employs feedback mechanisms where the processor continuously monitors screen configuration status (folded/unfolded states, rotation angles) and uses this information to adjust the touch display area configuration. This feedback loop enables the system to automatically respond to screen changes and maintain proper touch functionality across different configurations without requiring complex manual reconfiguration.
3Ease of operation
If the application interface is displayed on only one touch screen, then the control system is simple, but user operability is limited when screen configurations change
Solution Approach 1:
The patent implements dynamic interface distribution where the application interface automatically redistributes across multiple screens based on the current screen configuration. When screens are folded or unfolded, the processor dynamically determines which screens should display which portions of the interface and adjusts the touch response areas accordingly, maintaining seamless operability across different screen states.

AI summary
A control method includes obtaining screen change information of an electronic device and configuring a touch display area of the electronic device at least based on the screen change information to respond to a target touch operation using the configured target touch display area. The target touch display area is at least a part of display area of the display screen of the electronic device.
