A compensation table compression method is introduced, involving the division of reference and current frame compensation tables into coding blocks, which are processed using multiple prediction modes to obtain residual coding blocks, subsequently compressed through scanning, numerical scaling, and entropy coding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the compensation table size is increased to cover more pixels for uniform display, then the display quality is improved, but the system storage resource consumption increases
Solution Approach 1:
The compensation table is divided into multiple frame compensation tables (reference frame and current frame), which are further segmented into coding blocks. This segmentation allows selective processing and compression of different regions, reducing overall storage requirements while maintaining display uniformity.
Solution Approach 2:
The patent transforms the compensation table data through multiple prediction modes (intra-prediction, inter-prediction) and compression algorithms, changing the data representation parameters. This transforms the original large-size compensation data into a compressed form that occupies less storage space while preserving the necessary compensation information.
2Manufacturing precision
If the compensation table size is increased to cover more pixels, then the display quality is improved, but the data transfer time increases
Solution Approach 1:
By segmenting the large compensation table into smaller frame compensation tables and coding blocks, the total data volume to be transferred is reduced. The patent processes and transfers only the essential compensation information in a compressed format, significantly decreasing data transfer time while maintaining display quality.
Solution Approach 2:
The patent applies parameter changes through compression algorithms that transform the compensation data into a more compact representation. This reduces the data transmission volume and accelerates the burning process on the production line.
3Manufacturing precision
If the compensation table size is increased to cover more pixels, then the display quality is improved, but the hardware system complexity increases
Solution Approach 1:
The patent transforms the compensation data through parameter changes using prediction modes and compression algorithms. This reduces the data volume that needs to be stored and processed, allowing the use of simpler hardware systems with less memory capacity while still achieving the required display uniformity.
4Manufacturing precision
If the compensation table size is increased to cover more pixels, then the display quality is improved, but the data processing time increases
Solution Approach 1:
The patent segments the compensation table into manageable frame compensation tables and coding blocks, allowing for more efficient processing. By dividing the large dataset into smaller units that can be processed independently and in parallel, the overall processing time is reduced while maintaining the quality of compensation.
Solution Approach 2:
Through parameter changes using compression and prediction algorithms, the patent reduces the data volume that requires processing. This decreases the computational burden and processing time while preserving the essential compensation information needed for display uniformity.
