SENDING CARD – The card gets the video signal from external device via DVI input, and send the video image to the receiving cards.
PITCH – The distance between two close pixels, The lower the pitch – the better the picture quality.
MODULE – This is an array of pixels in plastic case, Complete unit, includes PCB, Driving ICs and
components, LEDs and epoxy for waterproofing ( OUTDOOR DISPLAY).
CABINET – An enclosure, Consist of several Modules including Power Suppliers, Ventilation, Receiving
