Introduce the composition, structure and characteristics of outdoor LED displays

Here we will like to introduce the composition, structure and characteristics of outdoor LED displays as well as cabinet types.

LED display screens are divided into indoor LED display screens and outdoor LED display screens according to the different use environments. The outdoor LED display must be in a box type. Outdoors are often affected by weather such as rain and fog, so the outdoor LED display must be waterproof. Due to the closed box structure of outdoor LED modules, it can be processed into an LED outdoor display screen box, which is then assembled into an outdoor full color LED display screen.

The benefits of adopting the LED box structure are as follows:

1. It is convenient for scheduling, aging, and on-site maintenance.

2. It is convenient for packaging and transportation.

3. It is easy to install and disassemble on site.

Module waterproof treatment

As far as the structure of outdoor full-color LED display is concerned, first of all, the module should be an outdoor fully waterproof module. Second, the back of the module should be painted with conformal coating. Third, the box should be a waterproof box with good sealing.

Cabinet structure

The display driver circuit board (LED module) is fixed inside the outdoor LED display box. The switching power supply is installed on the back cover of the box. An exhaust fan, air outlet, etc. are also installed on the back cover of the box. The inner and outer surfaces of the box are spray-coated with anti-corrosion, moisture-proof, anti-oxidation, flame-retardant and other functions to ensure the safety of the display screen.

Below we introduce to you in detail the cabinet types of outdoor LED display screens.

Type 1: Simplified iron/aluminum cabinet

The simple cabinet is suitable for most outdoor LED display scenarios. The front side of this type of box has better waterproof performance, but the back side needs to rely on a steel structure for waterproofing, so the requirements for the steel structure are higher. However, this type of cabinet is currently used less and less by customers because of its high installation cost.

Type 2: Fully sealed waterproof iron/aluminum cabinet

The fully waterproof outdoor cabinet is suitable for most outdoor LED display scenarios. The waterproof performance of the front and back of this type of box is very good, and the waterproof requirements of the steel structure are not high. The weight of this type of cabinet is approximately 50Kg/sqm. So far, this type of box has become the first choice for outdoor LED displays because of its high cost performance. In addition, it can also support high-definition outdoor 2.5mm solution (minimum viewing distance 2.5 meters).

Type 3: Front maintenance waterproof box

The front maintenance waterproof LED screen is suitable for places where there is insufficient space behind the screen and can be maintained by opening it from the front. Different from simple boxes and fully outdoor waterproof boxes, the rear maintenance box requires access to the screen through the back for maintenance operations. Therefore, when the back of the screen cannot reach the space where people can freely enter, the front maintenance box needs to be used.

Type 4: Custom-shaped fully sealed waterproof iron/aluminum cabinet

Custom-shaped cabinets include curved, right-angled and double-sided LED display cabinets.

The main purpose of curved or right-angled outdoor LED displays is to achieve a more three-dimensional and vivid effect, and through 3D technology, the images on the display can be made more three-dimensional, improving the audience's viewing experience. Curved cabinets can present a more natural and smooth surface effect, while right-angled cabinets can be used to create a variety of geometric shapes and patterns.

Double-sided LED displays are divided into two types. One is a cabinet that opens from the front side. This type of cabinet has certain size restrictions, usually the height does not exceed 1920mm, because a box that is too large is not conducive to transportation. The other is a front maintenance box that can remove the module from the front and perform maintenance. The box can also be made into a complete double-sided display LED display.

The most popular new product on the market right now is a new generation of lightweight, highly waterproof die-cast aluminum outdoor LED displays.

The outdoor fixed-installation die-cast aluminum waterproof LED display is an LED display product specially designed for outdoor environments with high protection level and stable performance. The latest products of this type have been fully optimized and updated in terms of structure, and their performance has also been comprehensively improved. It uses a special compact die-cast aluminum display box with very high splicing accuracy and is very convenient for disassembly, assembly and maintenance. In addition, it has high strength, impact resistance and corrosion resistance, and can adapt to various harsh outdoor environments. At the same time, the display also has multiple protection functions such as waterproof, dust-proof, and lightning protection to ensure that it can still work normally and stably under severe weather conditions.

Outdoor fixed-installation die-cast aluminum waterproof LED displays are mainly used in outdoor advertising, information release, traffic instructions, stage backgrounds and other fields, providing users with high-definition, high-brightness, high-contrast high-definition display effects. The resolution and display effect of this product have been continuously improved, and the new LED lamp beads have also greatly improved its brightness and contrast. Therefore, it has become an indispensable information dissemination tool in modern cities and is favored by users.

In addition, transparent screens and grille screens are also two products that have attracted much attention in the outdoor LED display market in recent years.

In the past two years, the transparent screen series products have been gradually improved to meet market demand.

The outdoor waterproof transparent screen with IP65 protection level not only has good permeability, but can also achieve excellent see-through performance while ensuring the display effect. Pixel pitch from P3.9-P15.6. Using die-cast aluminum as the box material, it has the characteristics of high precision, light weight, easy installation and wind resistance, and is widely used in outdoor places.

The grille screen adopts a special strip structure, which presents a grid-like effect and has good transparency and visual effects. It can be used in outdoor places such as building exterior curtain walls and roof installations. Grille screens usually use profile cabinet. The grid screen has the characteristics of light weight (19Kg/sqm), simple structure and flexible installation, and can transform the building wall into a media facade. The pixel pitch can be from P3.9-P31, which is the best choice for projects with long distance and large area of vision.
