Thermal patterning on hot LED panels is a thing of the past with ThermaCal. This feature is exclusive to Brompton R2-based panels that have been calibrated with Dynamic Calibration.

LEDs are affected by temperature, and all tend to be a bit less bright as they get hotter. The scale of this effect varies between the colours, meaning areas of an LED panel that are hotter or colder than the temperature the panel was calibrated at can show a colour shift.

What’s more, panels often heat up more in the centre than round their edges, which can lead to unsightly thermal patterns that mark out individual panels in the wall.


ThermaCal compensates for these effects and gives the user control of how much compensation is required based on the panel temperature and environment.

It does this by both separating thermal effects from the optical calibration and by profiling each panel type to understand in detail its thermal characteristics for a smooth, panel-specific correction.

The amount of correction can be adjusted dynamically, even during a show, to account for changes in temperature over time.


Legacy calibration techniques mix up optical and thermal characteristics in a single correction based on the temperature and module position at which they were calibrated.

The ThermaCal compensation is different – it’s applied at the panel level, so modules can be swapped around freely without introducing any visual artefacts.
