Dual-Screen Display Control via Spatial Rotation Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with dual screens lack flexibility in their usage, as the relative positional relationship between the screens is fixed, limiting user interaction and display control.
Innovation Solution
A display control method that determines the relative positional relationship between the surfaces of an electronic device's bodies and controls the display units based on this relationship, allowing for different types of spatial rotations and modes of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the dual-screen electronic device uses a fixed relative positional relationship between screens, then the device structure is simple and stable, but the usage flexibility and interaction diversity are limited
Solution Approach 1:
The patent applies the dynamics principle by enabling the first body to perform different spatial rotations (first rotation and second rotation) relative to the second body, transforming the fixed structural relationship into a dynamic, adjustable one. This allows the display surfaces to change their relative positions and orientations, providing multiple usage modes (such as laptop mode, presentation mode, collaboration mode) while maintaining a relatively simple mechanical connection structure.
2Adaptability or versatility
If the electronic device enables multiple types of spatial rotations between bodies, then the usage modes and user interaction diversity increase, but the device complexity and control difficulty increase
Solution Approach 1:
The patent applies the feedback principle by determining the relative positional relationship between the first and second bodies based on their spatial rotation states, and then using this information to control the working states of the display units. The system continuously monitors the rotational positions and adjusts the display configurations accordingly, providing automatic adaptation to different usage scenarios and reducing the burden on users to manually configure complex rotation settings.
Solution Approach 2:
The patent applies the universality principle by designing the control system to handle multiple types of spatial rotations (first rotation and second rotation) through a unified control architecture. The same control device manages both rotation types and coordinates the working states of multiple display units, allowing the system to provide diverse usage modes without requiring separate control mechanisms for each rotation type.
3Ease of operation
If the display control system automatically adjusts working states based on relative positional relationships, then user interaction convenience improves, but the measurement and detection requirements become more complex
Solution Approach 1:
The patent applies the self-service principle by enabling the display control system to automatically determine and respond to the relative positional relationships between bodies without requiring manual user input. The system self-adjusts the working states of the display units based on the detected spatial configuration, providing hands-free operation convenience. The device monitors its own state and makes appropriate adjustments autonomously.

AI summary
A display control method includes determining a first relative positional relationship between a first surface and/or a second surface of a first body of an electronic device and a first surface of a second body of the electronic device, the first relative positional relationship being related to at least one of a first rotation and a second rotation of the first body relative to the second body, a first display unit being disposed on the first surface of the first body, a second display unit being disposed on the second surface of the first body, the first rotation and the second rotation being different types of spatial rotation; and controlling at least one of the first display unit and the second display unit to be in a working state based on the first relative positional relationship.
