Brompton Technology is demonstrating its TrueLight tech for the first time at the Las Vegas NAB show.

The technology – driven by the new Tessera G1 receiver card – enables full calibration of the pixels and control of the light spectrum emitted by an LED panel with a broader spectral output, by utilising extra emitters in addition to the standard RGB format.

The demos of the new tech are being made in collaboration with ROE Visual who are showcasing their brand-new Carbon 5 RGBW panel powered by TrueLight. Carbon 5 RGBW is the first panel of its kind calibrated by Hydra to offer a fourth emitter providing a broad spectrum white.

TrueLight uses Brompton’s Dynamic Calibration technology, performed by the company’s Hydra advanced measurement system. The system provides complete spectrally-aware calibration for extra emitters to ensure colorimetric precision, full colour and luminance correction are applied on a per-pixel basis, delivering the image quality necessary for direct-view applications, including reflections. All possible RGBW spectral mixes are fully corrected, maintaining calibration accuracy at all times.

“Thanks to TrueLight technology, users can dynamically adapt the spectral behaviour using controls in the processor UI, including optionally disabling the ‘W’ LEDs for conventional fully-calibrated RGB-only operation,” said Cesar Caceres, Brompton’s Product Lead.

Frank Montero, Managing Director at ROE Visual US comments, “ROE is very proud to be investing in new technologies with Brompton. Brompton and ROE have long been successful partners in live events and virtual production. Our rapid collaboration on Carbon 5 RGBW is just a small measure of what we can accomplish together. It’s a perfect fit to launch the G1 card and our next generation of products together at NAB.”

Using the full range of Tessera software features, TrueLight takes advantage of PureTone for consistent linearity of both RGB and ‘W’ LED output, ThermaCal for temperature correction of all LED colours, ShutterSync to eliminate on-camera artifacts for RGBW lighting and direct-view applications, and Extended Bit Depth to significantly enhance the dynamic range of RGBW output, amongst others.

Chris Deighton, Brompton’s CTO, said: “There has been increasing interest in broader spectral output from LED panels, and we were determined to meet this demand without compromising the existing levels of image quality and flexibility expected by Brompton users. The immense processing power available in the G1 receiver card means TrueLight can perform spectrally-aware full-colour per-pixel calibration of all four RGBW LED colours, with fully dynamic controls to adapt the spectral behaviour in real-time. We’re incredibly excited to offer a world-first demonstration of TrueLight at NAB, and look forward to seeing how the industry adopts this technology to achieve ever more realistic in-camera visual effects.”

“TrueLight technology unlocks a whole new realm of possibilities for applications that demand uncompromising image quality and colour accuracy,” said Caceres. “Whether it’s virtual production, XR, simulation, theatre, fixed corporate installations, fashion, or retail, TrueLight represents an industry-changing solution for scenarios where the screen is used as a lighting source. TrueLight is the perfect choice for high-end applications that require nothing but the best.”
