Spliced Display Position Detection for Automatic Screen Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display scenarios where multiple electronic devices are spliced together, the lack of knowledge of each device's position can lead to display disorder, adversely affecting the viewing experience without the need for manual intervention or participation of additional devices.
Innovation Solution
Electronic devices determine their position in the spliced system based on the connection status of input ends and/or control commands from other devices, using control and feedback commands to establish row and column relationships, thereby avoiding display disorder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an image capture module and an analysis module are used to determine device positions in a spliced electronic device, then display order is maintained, but system complexity and costs increase
Solution Approach 1:
Each electronic device in the spliced system autonomously determines its own position by detecting connection status at its input ends and processing control commands, eliminating the need for external image capture modules and analysis modules. The device uses its own processor to execute positioning logic based on connection detection and command reception.
Solution Approach 2:
The patent extracts the positioning function from a centralized image capture and analysis system, distributing it to each individual electronic device. Each device independently performs position determination through connection status detection and control command processing, removing the need for dedicated imaging hardware and central analysis software.
2Reliability
If an image capture module and an analysis module are used to determine device positions, then display order is maintained, but costs increase
Solution Approach 1:
The patent replaces expensive, permanent imaging hardware (image capture modules) and software analysis systems with inexpensive, software-based connection status detection and control command processing. The positioning function is achieved through simple electrical connection detection and digital command exchange, which are significantly cheaper than dedicated imaging systems.
Solution Approach 2:
Each electronic device independently determines its own position using built-in detection capabilities and processing power, eliminating the need for external imaging equipment and centralized analysis software. This self-service approach reduces overall system costs by distributing the positioning function across all devices rather than requiring specialized expensive equipment.
3Reliability
If manual intervention is used to determine device positions in a spliced system, then display order can be controlled, but operation complexity and time consumption increase
Solution Approach 1:
The system implements automatic feedback mechanisms where electronic devices send control commands to neighboring devices based on detected connection status. Each device receives feedback about its connection state and automatically adjusts its position determination without manual intervention. The processor executes automated logic that continuously monitors connections and updates positioning information.
Solution Approach 2:
The patent establishes predetermined rules and protocols for position determination that are executed automatically when devices are connected. Control commands with predefined formats and meanings are exchanged between devices according to established protocols, eliminating the need for manual configuration or intervention during the splicing process.
4Device complexity
If each electronic device autonomously determines its position based on connection status and control commands, then system complexity and costs are reduced, but position determination accuracy must be maintained
Solution Approach 1:
The system uses multiple feedback mechanisms to ensure accurate position determination: connection status detection at input ends provides real-time information about device connectivity, control commands from neighboring devices provide positional references, and the processor continuously processes this feedback to calculate and verify position information with high accuracy.
Solution Approach 2:
Control commands serve as intermediaries that carry position information between neighboring electronic devices. These standardized commands facilitate accurate position determination by allowing devices to exchange positional data and coordination information without direct manual intervention, maintaining precision through structured communication protocols.

AI summary
An electronic device determines its position in a spliced electronic device, and, based on the position, determines content that should be displayed, to avoid display disorder. In addition, the electronic device determines its position in the spliced electronic device based only on a connection status of an input end, or based on both a connection status of an input end and a control command from another electronic device, where the control command indicates a position of another electronic device in the spliced electronic device. Neither manual intervention nor participation of another device is required.
