Display Control Device for Multi-Display Image Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where a user with a single display device discusses image content with a user having multiple displays, discrepancies in displayed images can hinder smooth discussion, as the users may be viewing different shared images.
Innovation Solution
A display control system that receives and synchronizes image information and identification data across multiple displays, allowing the remote connection terminal to superimpose and display this information correctly based on positional setting information, enabling users to identify and align the images being discussed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If screen sharing is implemented between devices with different display configurations, then communication between users is enabled, but discrepancies in displayed images occur causing confusion in discussion
Solution Approach 1:
The system performs preliminary actions by acquiring and storing identification information for each display area and setting information about positional relationships before actual screen sharing occurs. This preparation enables the remote connection terminal to later retrieve and use this information to correctly identify and align display areas, preventing image content discrepancies during communication.
Solution Approach 2:
The system establishes a feedback mechanism where identification information and setting information are transmitted from the screen sharing terminal to the remote connection terminal. This feedback loop allows the remote terminal to receive and process display area identification data, enabling it to correctly map and align the shared screen content with its own display areas, thus maintaining image content consistency.
2Quantity of substance
If multiple display areas are shared remotely, then comprehensive information transmission is achieved, but users cannot identify which display area corresponds to which physical display
Solution Approach 1:
The system applies visual markers (analogous to color changes) by superimposing identification information such as frame lines, icons, or labels on each display area. These visual indicators allow users to easily distinguish and identify which remote display area corresponds to which physical display, even when multiple display areas are being shared simultaneously, thus maintaining ease of operation while transmitting comprehensive information.
3Measurement precision
If display area identification information is transmitted, then correct alignment can be achieved, but data transmission volume and processing complexity increase
Solution Approach 1:
The system extracts only the essential identification information needed for display area alignment—such as positional coordinates, display area boundaries, and correspondence relationships—from the complete screen data. By transmitting only these extracted key parameters rather than entire screen content, the system achieves precise display area alignment while minimizing data transmission volume and processing complexity.
