Electronic Label Serial Interface for Multi-Screen Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic labels face high manufacturing costs and inflexibility in displaying content, particularly when multiple screens are required to show the same or different information, with existing solutions failing to provide efficient and cost-effective solutions for updating and diversifying display content.
Innovation Solution
An electronic label system comprising multiple display screens, a communicator, and a controller with a serial data interface that transmits content data and control signals synchronously, allowing for selective display on each screen and reducing the number of interfaces needed, thereby lowering costs and enhancing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display screens are used to show different or same content, then display flexibility and information diversity are improved, but manufacturing cost increases
Solution Approach 1:
The patent merges multiple display screens into a single electronic label device, allowing them to be controlled through a unified controller with a serial data interface. This integration enables multiple screens to display different or the same content simultaneously while sharing common control infrastructure, thereby improving display flexibility without proportionally increasing manufacturing cost.
Solution Approach 2:
The controller is designed with a universal serial data interface that can communicate with multiple display screens through a single interface. This multi-functional interface allows the same controller to manage different display screens, enabling content diversification and flexible display configurations without requiring separate dedicated interfaces for each screen, thus controlling manufacturing costs.
2Reliability
If separate interfaces are provided for each display screen, then control precision and data transmission reliability are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple interface functions into a single serial data interface. The controller uses this unified interface to transmit data and control signals to multiple display screens sequentially or simultaneously, reducing the total number of interfaces while maintaining reliable communication through proper signal timing and selection mechanisms.
Solution Approach 2:
The patent introduces a selection signal as an intermediary mechanism that works with the serial data interface to identify which display screen should receive the data. This selection signal acts as a mediator between the single serial interface and multiple display screens, enabling reliable data transmission to the correct screen without requiring separate dedicated interfaces for each display device.
3Productivity
If content data is transmitted to all display screens simultaneously, then update efficiency is improved, but data transmission error rate increases
Solution Approach 1:
The patent segments the data transmission process into distinct phases: first transmitting content data to all display screens simultaneously for efficient updates, then separately transmitting control signals with selection signals to specify which screen should display the content. This segmentation allows high-speed data transmission while preventing errors through proper protocol separation.
Solution Approach 2:
The patent incorporates feedback mechanisms where display screens acknowledge received data and control signals. The controller receives feedback information from display screens to confirm successful data reception and transmission status, allowing the system to detect and correct transmission errors while maintaining efficient simultaneous data updates across multiple screens.
