Solution Overview
Problem
Current RGB and multi-primary display systems are limited in color range and light output, leading to increased viewer metameric errors and higher operational costs due to narrow emissive spectra, and lack the ability to effectively vary color saturation beyond brightness changes.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional RGB systems use narrow emissive spectra to achieve color separation, then color gamut is limited, but viewer metameric errors increase and operational costs rise
Solution Approach 1:
The patent applies parameter changes by modifying the spectral characteristics of the display system. Specifically, it uses super-saturated color primaries with expanded spectral coverage beyond traditional RGB, changing the emission parameters to achieve both wide color gamut and reduced metameric errors through optimized spectral power distributions
Solution Approach 2:
The invention employs composite material principles by combining multiple spectral components in a unified display system. The super-saturated color primaries are formed by composite spectral structures that integrate multiple wavelength components, enabling simultaneous achievement of broad color gamut and low metameric error through synergistic spectral combinations
2Ease of operation
If traditional RGB systems are used, then device complexity is low, but color saturation cannot be varied independently of brightness
Solution Approach 1:
The patent implements dynamics by enabling independent control of color saturation and brightness through dynamic processing of color space parameters. The system dynamically adjusts saturation levels by manipulating chroma components separately from luminance, allowing flexible color control adapted to different display conditions and content requirements
Solution Approach 2:
The invention applies dimensionality change by adding an independent saturation control dimension to the traditional brightness-saturation coupling. Through transformation to super-saturated color space, the system creates an additional independent parameter space that allows saturation variation without brightness changes, enhancing color control versatility
3Measurement precision
If color gamut is expanded beyond traditional RGB, then color reproduction is enhanced, but compatibility with existing standards may be compromised
Solution Approach 1:
The patent applies universality by designing a multi-functional color processing system that can operate in both traditional RGB mode and super-saturated color mode. The system includes transformation capabilities that allow it to adapt to different color spaces and standards, maintaining backward compatibility while enabling enhanced color reproduction when needed
Solution Approach 2:
The invention uses parameter changes to maintain standard compatibility by implementing transformable color space parameters. The system can switch between standard RGB parameter sets and super-saturated color parameters, adjusting the mathematical representations to match different standards while preserving the enhanced color reproduction capabilities

AI summary
Systems and methods for displaying super saturated color. Image data for display on a display or viewing device with a potential white luminance in a standard system with a maximum luminance is processed such that colors near the white point are reduced to a limited luminance. As the chroma of the displayed color is increased, a luminance attenuation is decreased. The scaling of the reduction is operable to be a linear function, a non-linear function, or any other function.
