LED Processor
01 — Definition
The device that lays the video signal onto the physical LED panel layout and distributes data to the tile receiving cards. Each data output port has a pixel ceiling: exceed it and the refresh rate drops or artefacts appear. The big names: Novastar, Brompton Tessera, Megapixel VR Helios, Colorlight.
02 — In the field
An LED wall showing visible scan lines or flicker on camera? The processor's refresh rate is mismatched with the camera shutter speed. Set the processor to a refresh rate that is a clean multiple of the camera sensor's scan frequency.
