The internal structure of the LED display is mainly composed of the following parts:

Circuit board: The circuit board is one of the core parts of the LED display, covered with LED lamp beads, controllers, driver ICs and other components.

Lamp bead: LED lamp bead is the core light-emitting device of LED display. Each LED lamp bead has its own ID (identification number) and can be controlled individually.

Driver IC: The driver IC is one of the core components of the LED display. It is mainly used to control the brightness, current, voltage and other parameters of the LED lamp beads, so that the LED lamp beads can emit light normally.

Controller: The controller is one of the important components of the LED display, which is used to control the switch, brightness, color temperature and other parameters of the LED display to achieve various display effects.

Radiator: The radiator is used to ensure that the temperature inside the LED display is within the normal range, ensuring the stability and service life of the LED lamp beads.

Cabinet: The cabinet is the external structure of the LED display, used to protect the internal components of the LED display, and also has functions such as waterproof and dustproof.

Power supply: The LED display needs to use a power supply to power the light-emitting diodes. There are two commonly used power supplies: AC power supply and DC power supply.

In short, the internal structure of the LED display is composed of many components, and each component has its own function and function. Through reasonable design and combination, the display effect and function of the LED display can be realized.
