Multi-Display Layout Configuration via Automatic Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-display systems require manual setup and separate devices or processes to configure layout information, including rotation, for multiple display apparatuses to output a single image, leading to difficulties in smooth image output when user settings are improper.
Innovation Solution
A display apparatus and method that automatically configure layout information, including rotation, without user intervention by using a master display apparatus to transmit and receive position information from other display apparatuses, determining their positions and orientations, and adjusting the image signal accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual setting process is used to configure layout information, then user can control display arrangement, but setup complexity and time consumption increase
Solution Approach 1:
The display apparatus automatically detects its own position and orientation relative to other displays and configures layout information without requiring user intervention. The system performs self-service by autonomously determining its spatial relationship with neighboring displays and generating appropriate layout configurations.
Solution Approach 2:
The display apparatus transmits position information to adjacent displays and receives feedback from them to determine the overall layout. This bidirectional communication enables the system to automatically configure the multi-display arrangement by exchanging position data and adjusting layout information accordingly.
2Measurement precision
If separate device or process is used to detect display position, then layout information can be obtained, but device complexity increases
Solution Approach 1:
The display apparatus integrates multiple functions including display output, position detection, and layout configuration within a single system. The same device that displays content also detects its position relative to other displays and configures the layout information, eliminating the need for separate detection devices or processes.
Solution Approach 2:
The patent combines the functions of position detection and layout configuration into the display apparatus itself. Instead of using separate devices or processes, the system merges these functions so that the display apparatus autonomously detects its position and configures layout information in an integrated manner.
3Adaptability or versatility
If user manually configures layout information, then customization is possible, but reliability of image output decreases when settings are improper
Solution Approach 1:
The display apparatus automatically determines its position and orientation relative to other displays and configures layout information without user intervention. This self-service approach ensures that the layout configuration accurately reflects the actual physical arrangement, thereby improving the reliability of image output across different display configurations.
4Ease of operation
If automatic position detection is implemented, then user setting is eliminated, but communication requirements between displays increase
Solution Approach 1:
The display apparatus transmits position information to adjacent displays and receives feedback from them to determine the overall layout. This bidirectional communication enables automatic configuration while maintaining relatively simple communication protocols between neighboring displays, balancing automation benefits with communication requirements.
