Features：
1. Computer operating system: Windows 7 or above
2. The design incorporates screw fixing for enhanced maintenance, improving the safety of module installation.
3. The use of quick-connect aviation plugs allows for rapid and safe connection or disconnection of power cords and network cables, facilitating module power supply and signal transmission.
4. The raised platform design on the bottom of the cabinet protects the display screen when the cabinet touches the ground.
5. Manual corner protectors are designed at all four corners of the cabinet to prevent damage to the display screen during packaging or handling.
6. The LED display unit modules and unit cabinets adopt an industrial-grade rigid connection design, with no signal cables inside the cabinets, resulting in a clean and tidy appearance, stable connections, and fast installation and maintenance.
7. The LED display screen adopts a three-axis (X, Y, Z) adjustment mechanism, which can realize six-way arbitrary adjustment of the screen.
8. One box, one card, one power supply; freely combinable; supports hoisting, stacking, fixed installation, and H-frame installation.
9. Hard connection, fully supports hot-swapping, convenient and quick.
