In short

The data sheets of two LED video walls can be almost identical, and yet three years later one of them is patchy and faded while the other is not. The difference is almost always here: whose LED chip, whose driver IC and whose power supply sits inside the module. This category exists so that you can name these hidden items and ask for them to be stated in the quotation.

Where does it fit in the system? Every stage of the diagram is clickable — it takes you to that category.

Egy LED fal fő alkatrészei egymás mellett kiterítve — The parts of an LED wall laid out: module, receiving card, HUB, power supply, cables. Illustrative image.

LED modulok minőségellenőrzése gyártás közben — Modules being tested during production. The quality of that testing is what separates two panels that look identical on paper. Illustrative image.

How an LED wall is built up, from the lamp bead to the finished wall. A “module” and a “cabinet” are not the same thing: the module is the replaceable piece of the image, the cabinet is the mounting unit that also holds the power supply and the receiving card.
