LED screens are modular devices formed by several components:


Cabinets: they are the fundamental modular element for the assembly of the screen. Most giant LED screens are usually divided into a series of frames, which form the entire screen when joined together. LED cabinets make screen manufacture and transport easier.


Structural chassis: it is the frame that houses the other components of the cabinet. It can be manufactured in different materials according to the technical requirements of the installation.


LED boards or modules: electronic modules formed by an electronic board with LEDs and an outer plastic or metal carcass.


Power sources: they are responsible for transforming the voltage of the electrical network to power the other electronic components.


Data card: receives the image data that each cabinet will issue and distributes them to all the cabinet’s modules.


Data circuit: set of wiring used to connect the data cards with LED modules and to connect cabinets with each other.


Power circuit: set of wiring used to connect power supplies to the other electronic components of the cabinet and to interconnect all the cabinets with the conventional electrical network.
