Micro-pitch LED display die-casting box installation

At present, the indoor splicing large screen market is divided into three parts: micro-pitch LED display, DLP rear-projection splicing screen, and LCD LCD splicing screen. Among them, the micro-pitch LED display is the most prosperous, with seamless, high brightness, high grayscale, high Features such as contrast ratio and long service life are unmatched by other splicing types, so they have been highly recognized by the market and quickly seized a large share of the indoor splicing market.

Micro-pitch LED displays can bring so many excellent performances, which are inseparable from their perfect performance in terms of seamlessness and flatness. These are mainly beneficial to the key processes and box structures used in the manufacture of micro-pitch LEDs. That is, high-precision CNC machining technology and die-casting aluminum box. Let’s briefly introduce the structure and installation of the LED box.


1. Bracket magnetic installation

The bracket magnetic installation method is mainly used in applications where the display effect requirements are not too strict and the front maintenance is not required. The rear installation space is not required. The installation is simple, but there is almost no flatness and seam adjustment mechanism design. After installation, it is necessary to adjust the LED. Compared with other installation methods, it is difficult to ensure the flatness and seam of the whole screen after installation, and the consequence of this is that the display effect is average.

2. Simple box type installation

For the LED display unit using this installation method, the receiving card and switching power supply are generally integrated into the box, and there is no need to install and configure wiring. Requirements, easy installation and maintenance, and post-maintenance use; the processing technology of the box is relatively crude and the accuracy is not high; the result is that the adjustment accuracy of the seam and flatness is general.

3. Traditional die-casting aluminum box installation

Each display unit box adopts high-standard mold-level processing, small die-casting aluminum structure, high-precision CNC processing, adopts modular installation structure, and has seam and flatness adjustment mechanism, such as Voury’s micro-pitch LED display, Using seam fine-tuning technology, the error of both horizontal and vertical adjustment is less than or equal to 0.01mm, so that the splicing error is almost zero, the screen body is flat without bumps, the bright and dark lines of the picture are eliminated, and the flatness of the whole screen is <0.1mm.
