Nowadays, the small-pitch outdoor full-color LED display market occupies a pivotal position in the global market. Among them, the full-color LED display has the strongest momentum. Its seamless, high brightness, high grayscale, high contrast, long life and other characteristics are other splicing The form is incomparable, so it has been highly recognized by the market and quickly occupied a huge share of the commercial outdoor display market.

Small-pitch outdoor full-color LED display can bring such excellent performance, it is inseparable from its perfect performance in seamless and flatness, which is mainly conducive to the key technology applied in the production of small-pitch outdoor full-color LED display And the box structure, that is, high-precision CNC machining technology and die-cast aluminum box. The following briefly introduces the installation method of the LED box.

As for the installation of small-pitch outdoor full-color LED display cabinets, currently, the installation of LED display cabinets mainly includes the following categories:

1. Installation of bracket magnetic device.

The small-pitch outdoor full-color LED display bracket adopts a magnetic installation method, which is mainly used in applications where the display effect and front maintenance requirements are low. There is no rear space, but there is very little flatness and flat seam adjustment mechanism design. After installation, the LED control system and rear wiring need to be installed. Compared with other installation methods, it is difficult to ensure the flatness and splicing of the entire screen after installation, and the display effect is average.

2. Simple box installation method.

The small-pitch outdoor full-color LED display unit adopts this installation method, the receiving card and the switching power supply are generally integrated in the box, and there is no need to install and configure the wiring separately. The chassis is mainly made of iron sheet, and the installation is relatively simple. It is mainly used where the display effect is required. It is easy to install and maintain, and easy to repair; the chassis processing technology is rough and the accuracy is not high; therefore, the adjustment accuracy of flat seams and flatness is average.

3. Installation of traditional die-cast aluminum cabinet.

Each display unit of the small-pitch outdoor full-color LED display adopts high-standard mold processing, miniaturized die-cast aluminum structure, high-precision numerical control processing, modular installation structure, flat seam and flatness adjustment mechanism, such as Winbond’s small Pitch full-color LED display, fine-tuning of flat seam technology. The horizontal and vertical adjustment error is 0.01mm, the splicing error is basically zero, the screen body is flat and has no protrusions, and the light and dark lines are eliminated. The full screen smoothness is less than 0.1 mm.
