Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple layer data are blended to generate pixel values for high resolution display, then the display quality enhancement is achieved, but the processing complexity increases due to the need to apply different display quality enhancement algorithms to different pixels
Solution Approach 1:
The patent segments the display screen into multiple regions based on pixel type characteristics. Different display quality enhancement algorithms are applied to different pixel segments (e.g., sub-pixels with different colors or positions) rather than applying a uniform algorithm to all pixels. This segmentation approach enables tailored enhancement for each pixel type while managing processing complexity through region-based classification.
Solution Approach 2:
The patent implements local quality enhancement by generating pixel map data that assigns specific display quality enhancement algorithms to individual pixels or pixel groups based on their characteristics. Each pixel can have its own enhancement algorithm selected from multiple options, allowing localized optimization of display quality for different pixel types (e.g., different sub-pixels, different screen regions) rather than applying a single global enhancement method.
2Manufacturing precision
If display quality enhancement algorithms are applied to each pixel based on pixel map data, then the image rendering quality is improved, but the processing time increases
Solution Approach 1:
The patent performs preliminary action by generating pixel map data in advance that pre-identifies which display quality enhancement algorithm should be applied to each pixel. This pixel map data is prepared before the actual image rendering process, allowing the system to quickly reference pre-determined algorithm assignments during rendering rather than making algorithm selection decisions in real-time for each pixel, thereby reducing processing time while maintaining enhancement quality.
