BROMPTON TECHNOLOGY UNLEASHES UNPARALLELED PERFORMANCE WITH DYNAMIC CALIBRATION

Brompton Technology’s Dynamic Calibration is a ground-breaking new technology that enables LED panels to achieve a higher brightness and wider colour gamut than is possible with legacy calibration techniques, while maintaining uniformity. Dynamic Calibration is the enabling technology for Brompton HDR, as well as new, performance-enhancing features such as PureTone and ThermaCal.

“Commonly used calibration methods achieve uniformity by sacrificing both brightness and colour gamut, forcing every LED to match the dimmest and palest LEDs in the entire screen. Once calibrated, this is used for all content over the entire life of the panel,” explains Brompton’s CTO Chris Deighton. “However, with ever-increasing demand for better image quality without increased cost, such sacrifices in performance can no longer be justified.”

Brompton’s Dynamic Calibration is unique and takes a revolutionary approach to maintaining uniformity, while unlocking the full potential of the LEDs to achieve previously unthinkable levels of brightness and colour saturation.

To benefit from Dynamic Calibration an LED panel must be fitted with a Brompton Tessera R2 receiver card and needs to be measured using Hydra – an advanced measurement system custom-designed for LED panels and exclusive to Brompton Technology.

“Dynamic Calibration is a flexible approach that uses the immense parallel computing power of the R2’s Dynamic Engine to process incoming video in an entirely new and innovative way,” says Deighton. “Before making any decisions, the Dynamic Engine gathers a vast array of data, including the incoming video pixels, the video signal’s metadata, Dynamic Calibration metadata, the precise capabilities of each individual LED and the user’s preferences for how the image should be displayed.”

All of this extra information is processed in real-time, with no added latency, to intelligently determine the best possible way to drive each LED. Areas of the image where peak brightness is the most important visual aspect will make full use of the LEDs’ peak brightness. Areas requiring extreme saturation will make full use of the LEDs’ maximum colour gamut. But all this is achieved without needlessly sacrificing uniformity across the rest of the image.

The result of this unique approach is a huge step forward in visual performance. Brighter whites, higher contrast ratios, more saturated colours, and true-to-life colour accuracy deliver a previously unattainable level of image depth and realism. Lifelike colour and brightness without the compromises inherent to legacy calibration.

The dynamic nature of the system means the desired brightness, primary colours and white point are all fully user-adjustable. What would previously have required a lengthy and expensive recalibration process can now be done at any time from the simple new DynaCal user interface on any Tessera processor, with changes seamlessly reflected in real-time on the screen – even during a live event.

Zebra indicators can be enabled to highlight areas of the image that are trying to drive the LEDs beyond their peak brightness or colour gamut, allowing rapid fine-tuning of screen performance based on the content, viewing environment and user preferences.

Colour accuracy is managed throughout the entire system. Even with no user configuration, colours are perfectly balanced, skin-tones look natural and content looks just the way its author intended.

“Dynamic Calibration is not just for brand new LED panels,” Deighton concludes. “It also allows existing panels using the Tessera R2 card to be given a new lease of life and it is supported by all Tessera processors as a free software upgrade.”
