Wireless Spliced Screen Control via Time Code Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spliced screen systems rely on fixed, wired installations for sub-display screens, limiting flexibility and reliability, especially in large-scale performances where wireless and flexible control is necessary.
Innovation Solution
A display control method that uses a wireless display control signal sent by a display controller to each sub-display screen based on a time code signal, allowing for independent wireless transmission and reception, and enabling each sub-display screen to report status information and perform corresponding display processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If sub-display screens are fixedly installed on supporting structures with wired transmission, then display stability is improved, but flexibility and adaptability deteriorate
Solution Approach 1:
The patent replaces the mechanical wired transmission system with a wireless transmission system. The display controller wirelessly transmits control signals to sub-display screens via radio frequency communication, eliminating the need for physical cable connections while maintaining control stability and enhancing flexibility in installation and configuration.
2Reliability
If wired transmission is used for display control signals, then signal transmission reliability is improved, but system complexity and installation difficulty increase
Solution Approach 1:
The patent substitutes the complex wired transmission system with a wireless communication system. The display controller uses radio frequency modules to transmit control signals without physical cables, reducing installation complexity and maintaining reliable signal transmission through wireless protocols.
3Ease of operation
If sub-display screens operate independently without centralized control, then ease of operation is improved, but display synchronization and coordination deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where sub-display screens report their operational status to the display controller. The controller receives status information from each sub-display screen and adjusts control signals accordingly, ensuring synchronized operation while allowing independent device architecture. This feedback loop maintains display coherence across all sub-screens.
Solution Approach 2:
The patent divides the display system into independent sub-display screens that can operate autonomously but are coordinated through wireless communication. Each sub-display screen functions independently with its own processing capabilities while receiving synchronized control signals from the display controller, achieving both independence and coordination.
