Display Data Interface Device With 10-Bit To 11-Bit Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High data transfer rates between a timing controller and a source driver in display apparatuses lead to data transfer errors, and existing encoding and decoding technologies face challenges in balancing maximum run length and DC balance, resulting in increased overhead and complexity.
Innovation Solution
A data interface device with an embedded encoder that encodes a 10-bit original data packet as an 11-bit transfer packet, setting a maximum run length of 5 and a DC balance of 8:3, and an embedded decoder that decodes the 11-bit packet back to 10-bits using case delimiters to minimize overhead and reduce data transfer errors.

Engineering Contradiction Analysis
1Reliability
If encoding technology is used to reduce data transfer error rate, then data transfer reliability is improved, but overhead increases and decoding process becomes complicated
Solution Approach 1:
The patent applies parameter changes by modifying the data packet structure from 10-bit to 11-bit, setting specific maximum run length (5) and DC balance (8:3) parameters. This controlled parameter change achieves reliable data transfer while keeping the encoding/decoding process simple and overhead minimal.
2Reliability
If the number of data bits is extended to satisfy encoding conditions, then data transfer error rate is reduced, but overhead increases and high-speed transfer becomes difficult
Solution Approach 1:
The patent extends the data bits from 10 to 11 and sets specific parameters (maximum run length of 5, DC balance of 8:3) to achieve reliable high-speed data transfer. This controlled parameter change reduces error rate while maintaining high transfer speed capability.
3Productivity
If overhead is reduced by minimizing bit extension, then data transfer efficiency is improved, but encoding conditions for reducing error rate become harder to satisfy
Solution Approach 1:
The patent achieves optimal balance by extending bits from 10 to 11 (minimal overhead) and setting specific parameters (maximum run length 5, DC balance 8:3). This minimal parameter change satisfies encoding conditions for error reduction while maintaining high transfer efficiency.
