Subpixel Arrangement for Multi-Primary Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing matrix displays face a reduction in overall image quality due to the addition of more primary colors, leading to color and luminance errors, and poor homogeneity, especially in black and white transitions.
Innovation Solution
The display elements are arranged such that the pair with the maximum color distance is positioned at a minimal spatial distance, often next to each other, optimizing the arrangement for enhanced color and luminance homogeneity, and using sub-pixel algorithms to maintain image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more primary colors are added to the display elements, then the color gamut and color accuracy are improved, but the image quality deteriorates due to color and luminance errors
Solution Approach 1:
The patent applies local quality by arranging different colors (red, green, blue, yellow) in specific spatial patterns where each position has a defined role. The arrangement ensures that colors with maximum chromatic distance are positioned adjacently to minimize color errors locally, while maintaining overall image quality through structured organization of display elements.
Solution Approach 2:
The patent changes the spatial arrangement parameters of display elements by positioning colors based on their chromatic distance relationships. By optimizing the spatial parameters (adjacent vs. non-adjacent positioning) based on color properties, the system achieves improved color gamut while maintaining image quality through parameter-optimized configuration.
2Adaptability or versatility
If more primary colors are added to the display elements, then the color representation is improved, but the homogeneity deteriorates due to color and luminance errors
Solution Approach 1:
The patent implements local quality by creating specific spatial relationships between different colors. Colors with maximum chromatic distance are positioned adjacently to exploit local variations in a controlled manner, while the overall pattern maintains homogeneity through systematic arrangement. This local optimization strategy improves color representation while managing homogeneity through structured design.
Solution Approach 2:
The patent applies asymmetry by positioning colors based on their unique chromatic properties rather than using symmetric or uniform distribution. The asymmetric arrangement places colors with maximum distance relationships adjacently, creating an optimized non-uniform pattern that improves color representation while maintaining visual homogeneity through deliberate asymmetric design.
3Ease of manufacture
If display resolution is reduced, then the manufacturing cost is reduced, but the image quality deteriorates
Solution Approach 1:
The patent changes the spatial arrangement parameters of display elements to optimize the relationship between resolution and image quality. By positioning colors based on chromatic distance relationships, the system achieves better color accuracy at lower resolutions, effectively decoupling the direct proportionality between resolution and image quality that typically exists in conventional displays.
