Industry: Medical display OEM / healthcare
Engagement type: Firmware development and factory calibration tooling

Medical display OEMs often need one physical display product to serve several clinical environments: radiology, pathology, surgery, general clinical review, and shared multi-modality rooms. Each environment can require different colour temperature, luminance, and gamma behaviour.

Advantech partnered with QUBYX to create a flexible multi-preset calibration architecture embedded directly into display hardware.

The challenge

Advantech OEM customers needed displays that could operate across multiple clinical modes without hardware changes, external software, or manual recalibration by staff.

The QUBYX solution

9-LUT firmware for the Realtek scaler

QUBYX developed custom firmware for the Realtek scaler that extends the display native capability to support nine independent LUTs stored on-device. Each LUT defines a complete display calibration state, allowing one hardware product to behave as multiple calibrated display modes.

Factory multi-LUT calibration tool

QUBYX also developed a factory calibration tool that measures the display optical response and computes LUT data for all nine target profiles in a single production pass. This avoids the inefficiency of calibrating each mode sequentially.

Physical LUT selector

Clinical staff switch between calibrated presets through a physical roller on the display bezel. No driver, software workflow, or external measurement device is required for mode selection.

Results

This project shows how QUBYX can combine scaler firmware expertise with calibration tooling for medical OEM display manufacturers.

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.

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

This engagement demonstrates how QUBYX supports OEM partners with end-to-end colour engineering: measurement, gamut computation, 3D LUT generation, and runtime integration.
