Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing color systems, particularly RGB systems, struggle to achieve a wide gamut with an increased number of primary colors, limiting color reproduction capabilities.
Innovation Solution
A multi-primary color system utilizing a graphics processing unit (GPU), display engine, and display controller to render and display image data with independent luminance and two colorimetric coordinates, applying non-linear transfer functions to enhance color gamut, including a system for encoding and decoding image data in the CIE Yxy color space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional RGB color system is used, then the system complexity remains low, but the color gamut is limited and cannot reproduce a wide range of colors
Solution Approach 1:
The patent transitions from a traditional 3-primary (RGB) color system to a multi-primary color system by adding more primary colors (yellow, cyan, magenta, and white), effectively adding dimensions to the color space. This dimensional expansion allows the system to reproduce a wider gamut of colors while maintaining a structured approach to managing the increased complexity through specialized processing units.
2Adaptability or versatility
If the number of primary colors is increased to expand color gamut, then color reproduction capability is improved, but the difficulty of detecting and measuring color data increases
Solution Approach 1:
The patent segments the color processing task into distinct functional components: a colorimetric coordinate converter that handles the mathematical transformation from multi-primary color space to displayable color space, and a display controller that manages the actual rendering. This segmentation simplifies the overall complexity by breaking down the difficult task of multi-primary color measurement and processing into manageable, specialized modules.
3Adaptability or versatility
If a multi-primary color system is implemented, then color gamut is significantly expanded, but the device complexity increases due to additional processing requirements
Solution Approach 1:
The patent introduces a colorimetric coordinate converter as an intermediary component between the multi-primary color input and the display device. This converter acts as a mediator that performs the complex mathematical transformations required to map multi-primary color data into a displayable color space, thereby managing processing complexity by isolating the complex calculations in a dedicated intermediate module rather than distributing them throughout the entire system.
