Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed communication errors in display devices can occur due to noise, such as static electricity, leading to image quality degradation, as the preconfigured communication environment may be altered, and existing methods do not effectively detect or correct these errors in real-time.
Innovation Solution
A method and system for repeatedly checking error detection information in both low-speed and high-speed communication environments to determine if errors have occurred, allowing for immediate reconfiguration of the high-speed communication environment by retransmitting configuration value data and error detection information, ensuring stable image data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-speed communication is used for data transmission, then communication speed is improved, but error occurrence increases due to noise and static electricity
Solution Approach 1:
The patent applies preliminary action by performing low-speed communication before high-speed communication to configure the communication environment and transmit error detection information in advance. This allows the system to prepare error detection mechanisms before switching to high-speed mode, enabling early detection of potential errors while maintaining high-speed data transmission capability.
Solution Approach 2:
The patent implements feedback by continuously monitoring error detection information during and after high-speed communication. The system receives error detection information through both low-speed and high-speed communication channels, compares these values, and uses the comparison results to determine whether errors have occurred, creating a closed-loop feedback mechanism for error detection and correction.
2Reliability
If low-speed communication is used for configuration, then error occurrence is reduced, but communication efficiency decreases
Solution Approach 1:
The patent applies segmentation by dividing communication into distinct phases: low-speed communication for configuration and error detection information transmission, and high-speed communication for image data transmission. This segmentation allows each communication mode to be optimized for its specific purpose, maintaining reliability during configuration while achieving high productivity during data transmission.
Solution Approach 2:
The patent implements periodic action by alternately using low-speed and high-speed communication modes. Low-speed communication is performed periodically to transmit error detection information and configure the communication environment, while high-speed communication is used for the majority of data transmission. This periodic switching ensures both reliability and efficiency are maintained.
3Measurement precision
If error detection is performed repeatedly, then error detection capability is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by using the same communication channels (main line and auxiliary line) for multiple purposes: transmitting image data, configuration information, and error detection information. This multi-functional use of existing channels enables repeated error detection without requiring additional dedicated hardware, thus improving error detection capability while minimizing system complexity.
Solution Approach 2:
The patent implements self-service by enabling the communication system to detect and identify errors using its own built-in error detection information mechanisms. The system transmits error detection information through the communication channels and uses comparison of these values to self-diagnose errors, reducing the need for external error detection hardware and simplifying the overall system.
