Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The first signal line in panel driver circuits has lower transmission efficiency and utilization rate due to its lower data transmission capacity, requiring multiple instructions and preambles for data transmission, which reduces overall efficiency.
Innovation Solution
A drive control method that uses point-to-point configuration instructions with Manchester encoding, allowing a single instruction to carry multiple data bytes, reducing the need for preambles, start identifiers, and stop identifiers, thereby enhancing transmission efficiency and utilization rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional configuration instructions with preambles and identifiers are used on the first signal line, then data transmission reliability is maintained, but transmission efficiency and utilization rate deteriorate due to multiple instructions required for each data byte
Solution Approach 1:
The patent merges multiple data bytes into a single configuration instruction by removing redundant preambles and identifiers. Instead of sending separate instructions for each byte with full protocol overhead, the invention combines multiple data bytes into one streamlined instruction structure, significantly improving transmission efficiency and utilization rate of the first signal line
Solution Approach 2:
The first signal line is designed to serve multiple functions: it can transmit both traditional configuration instructions with preambles and identifiers, and the new compact multi-byte instructions without these overhead elements. This multi-functionality allows the system to maintain compatibility while achieving higher transmission efficiency
2Measurement precision
If multiple preambles and identifiers are included in each instruction, then data transmission accuracy is improved, but the utilization rate of the first signal line deteriorates due to increased overhead
Solution Approach 1:
The patent combines multiple data bytes into a single instruction structure that includes a single preamble and identifier set shared across all bytes in the instruction. This merging eliminates the need for redundant overhead elements for each individual byte, thereby improving signal line utilization rate while maintaining data transmission accuracy through the shared protocol elements
3Speed
If traditional one-byte-at-a-time transmission is used on the first signal line, then protocol compatibility is maintained, but transmission speed deteriorates due to repeated protocol overhead
Solution Approach 1:
The patent merges multiple data bytes into a single transmission unit (configuration instruction) that can be sent in one go rather than byte-by-byte. This merging approach increases transmission speed by eliminating repeated protocol overhead, while the instruction structure maintains compatibility with existing protocols through the use of standardized preambles and identifiers
Solution Approach 2:
The invention transitions from a one-dimensional byte-by-byte transmission approach to a multi-dimensional approach where multiple bytes are packaged together in a single instruction structure. This dimensional change allows for more efficient use of the signal line while maintaining protocol compatibility at the boundary interfaces
