At present, the indoor splicing large-screen market has three parts of the world for small-pitch LED displays, DLP rear-projection splicing screens, and LCD LCD splicing screens. Among them, small-pitch LED displays have the most momentum, with no seams, high brightness, high grayscale, and high Contrast, long service life and other characteristics are unmatched by other splicing types, so it has been highly recognized by the market and quickly grabbed a large share of the indoor splicing market.
Small pitch led display
The micro-pitch LED display can bring so many excellent performances, and its perfect performance in seamless and flatness is inseparable, and these are mainly benefited from the key processes and box structure used in the manufacture of micro-pitch LEDs. Namely, the high-precision CNC machining process and die-cast aluminum cabinet, let's briefly introduce the structure and installation of the LED cabinet.
1. Bracket magnetic installation
The bracket magnetic installation method is mainly used in applications where the display effect requirements are not 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, the LED needs to be adjusted. Compared with other installation methods, it is difficult to ensure the flatness and seam of the entire screen after installation. The consequence of this is that the display effect is average.
2. Simple box installation
In the LED display unit with 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. The box is mainly made of iron sheet material, and the installation is relatively simple. It is mainly used to improve the display effect. Requirements, easy to install, maintain, and use after maintenance; the processing technology of the box body is relatively crude and the accuracy is not high; the result is that the adjustment accuracy of the seam and flatness is average.
3. Installation of traditional die-cast aluminum cabinet
Each display unit box is processed with high-standard mold-level processing, small die-cast aluminum structure, high-precision CNC processing, modular installation structure, with seam and flatness adjustment mechanism, such as Voury's micro-pitch LED display, Using splicing fine-tuning technology, the horizontal and vertical adjustment errors are less than 0.01mm, so that the splicing error is almost zero, the screen body is flat without unevenness, the bright and dark lines of the screen are eliminated, and the flatness of the entire screen is <0.1mm.
