Multi-Primary Color System Expanding Gamut
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current color systems, particularly in electronic displays, are limited in their range of color reproduction and light output, leading to increased viewer metameric errors and higher operational costs due to the need for increased power from lower illumination sources, and they lack the ability to effectively expand color gamuts beyond the traditional RGB model.
Innovation Solution
A multi-primary color system that includes at least six primaries, such as red, green, blue, cyan, magenta, and yellow, operating within the CIE Yu′v′ color space, with an image data converter that encodes and decodes data using non-linear functions to enhance color gamut and luminance, allowing for the transportation of additional color primary information beyond the display itself.

Engineering Contradiction Analysis
1Adaptability or versatility
If traditional RGB color system is used, then device complexity is low, but color gamut is limited
Solution Approach 1:
The color system is segmented into multiple independent primary color channels (R, G, B, C, M, Y) instead of using a single integrated RGB system. Each primary color can be independently controlled and optimized, allowing the system to achieve expanded color gamut while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The system transitions from the traditional three-dimensional RGB color space to a six-dimensional color space by adding three more primary colors (Cyan, Magenta, Yellow). This dimensional expansion allows representation of a significantly larger color volume, achieving wider color gamut beyond what is possible with conventional three-primary systems.
2Use of energy by moving object
If lower illumination sources are used, then power consumption is reduced, but metameric errors increase
Solution Approach 1:
The system changes the spectral parameters of the illumination sources by using six distinct primary colors with carefully selected wavelength characteristics. This parameter optimization allows lower power consumption while maintaining color accuracy, as each primary color is chosen to minimize metamerism and maximize color differentiation at reduced illumination levels.
