How QUBYX helped Audi AG harmonise colour across up to five independent vehicle cockpit displays using common gamut mapping and real-time per-display 3D LUTs.
Industry: Automotive / in-vehicle display systems
Engagement type: Custom software and 3D LUT engineering
Modern premium vehicles now include several independent displays: instrument cluster, centre infotainment, passenger screen, head-up display, and rear-seat entertainment. Even when every screen is calibrated to the same white point and gamma, differences in panel technology, backlight behaviour, and manufacturing tolerance can make the same content look visibly different from one display to another.
Audi AG partnered with QUBYX to harmonise colour across vehicle cockpit systems featuring up to five independent displays.
The challenge
The cockpit displays were individually calibrated, but they still rendered colours differently because each panel had a different native colour gamut. Point calibration alone could not solve the problem: white point and gamma correction do not reshape the full colour volume of a display.
- Up to five independent screens per vehicle
- Mixed panel vendors and backlight technologies
- No single hardware colour engine spanning all displays
- Real-time correction required without visible latency
- Deployment inside the existing vehicle software stack
The QUBYX solution
Common gamut mapping and 3D LUT generation
QUBYX engineered a measurement and computation tool that characterises each display native colour gamut using spectral measurements. The tool calculates a common target gamut: the intersection of the reproducible colour spaces across all displays. It then generates a unique per-display 3D LUT that transforms each screen output toward the shared target.
Real-time 3D LUT viewer frame
To apply those corrections at runtime, QUBYX developed a lightweight viewer rendering frame. This software layer applies the 3D LUT transformation before pixels reach the panel, integrating into the vehicle display software architecture with no perceptible latency.
Results
- Up to five cockpit displays harmonised to a common gamut
- Per-display 3D LUT correction based on individual gamut characterisation
- Runtime correction applied in real time
- Consistent colour appearance across heterogeneous display hardware
This engagement demonstrates how QUBYX supports OEM partners with end-to-end colour engineering: measurement, gamut computation, 3D LUT generation, and runtime integration.
