Multi-display system layout swapping via position exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-display systems require cumbersome and costly operations to change display layouts, often necessitating high-throughput CPUs and sensors to adjust based on input images, resolution, and audience positions.
Innovation Solution
A multi-display system with display apparatuses that include a display section, operation input section, communication section, and control section, allowing for easy swapping of picture positions through communication and control message exchange without the need for high-throughput CPUs or sensors, using existing OSD functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic display layout changing is implemented using sensors and high-throughput CPUs, then the ease of operation is improved, but the device complexity and cost increase
Solution Approach 1:
The display apparatus automatically performs layout changing operations by detecting operation inputs and autonomously determining the changed layout configuration, eliminating the need for complex sensor systems and high-throughput CPUs while maintaining ease of operation
Solution Approach 2:
A layout changing notification is used as an intermediary signal to coordinate between display apparatuses, enabling automatic layout changes through simple communication rather than complex processing
2Device complexity
If manual layout changing is implemented through OSD functions, then the device complexity is reduced, but the ease of operation deteriorates due to cumbersome operations
Solution Approach 1:
The display apparatus automatically executes layout changing operations upon receiving a layout changing notification, eliminating the need for users to manually adjust settings through OSD functions while maintaining simple system configuration
Solution Approach 2:
The system prepares for automatic layout changing by having display apparatuses ready to receive and process layout changing notifications, enabling quick layout adjustments without manual intervention
3Adaptability or versatility
If picture position information is exchanged between display apparatuses, then the adaptability is improved, but the device complexity increases due to communication requirements
Solution Approach 1:
The communication section performs multiple functions including picture position information exchange and layout changing notification reception, enabling flexible layout changes without requiring dedicated complex communication infrastructure

AI summary
Display apparatuses which constitute a multi-display system each display a partial picture corresponding to a picture position set in the display apparatus. When each display apparatus is instructed to change the picture position and is notified about a picture position to be changed via operation input means, the display apparatus exchanges pieces of picture position information with a display apparatus displaying a partial picture corresponding to the picture position to be changed and swaps the picture positions of the display apparatuses.
