LED display screen is now used in more and more fields. The large LED electronic screen is composed of LED lamp beads, unit modules, unit boxes, control cards, power supplies, wire and network cables. When the application fields and installation environments are different, the installation methods of LED display screen are also different. To this end, LED display manufacturers develop different design schemes according to the needs of different users. What should we pay attention to before and after the installation of LED display? What are the main application fields of LED display?

The indoor protection grade of LED electronic large screen is generally IP43, the protection grade of LED outdoor display screen is IP65, and the protection grade of departments and regions is required to reach IP68. While LED indoor display screen generally does not have waterproof function, LED outdoor display screen, on the contrary, can be used in rainy days and high temperatures. In addition, the installation environment of LED outdoor display screen is relatively complex, while indoor display screen is relatively simple. The brightness of outdoor display screen is also higher than that of indoor display screen. The following is a brief introduction of the four major links that cannot be ignored in the LED electronic large screen by the manufacturer of Huaxintong Optoelectronic LED display screen.

Field investigation

Both indoor and outdoor LED electronic large screens need to be surveyed on the spot according to the actual situation. That is, before installing the LED electronic large screen, the LED display manufacturer will send technicians to the installation site designated by the customer to check the installation environment, measure the size, terrain, landform, brightness acceptance, and whether the installation location meets the specifications and luminous radiation range for testing. If the field test data is different from the display parameters produced by the LED display manufacturer, the LED display manufacturer must modify the product parameters based on the parameters returned from the test, and then customize the production.

Generally speaking, the installation of LED indoor display screen is usually to fix the welded square steel structure at the installation position, and then install the module, control card and power supply, or install the box. However, if the LED outdoor display screen is installed at a high position, it is necessary to implement a unified lifting scheme for the commanders to ensure that the unit box and structure can be installed at the designated position. In addition, different installation schemes need to be formulated for different installation environments.

Before installing the large LED electronic screen, it is necessary to determine whether the installation position is the roof, wall, column or hanging advertising screen. During actual installation, cranes and hoists shall be used for sectional hoisting according to the distance and height, and the above personnel shall cooperate with each other, especially for aerial operation. After installation, the gap of the LED electronic large screen shall be fine adjusted to ensure that the whole screen is seamless.


This is the LED display project of Shenzhen Fumin Police Station, China, completed by Sostron. Led display screen shows more information for the police and provides more reliable guarantee for everyone's safe travel.

Luminous radiation debugging

After the installation, the LED display manufacturer also needs to debug the luminous radiation range of the LED electronic large screen, that is, the viewing angle. Because the luminous radiation range of each direction is different, the perspective of building LED electronic large screen is also different. The installation shall be carried out according to the field acceptance ability and the ordinary perspective range of the audience. To ensure that you can see clear, balanced brightness, moderate brightness and high contrast, subtitle information and other suitable distances from every angle.

Inspection and maintenance

The LED display manufacturer will conduct aging test on the products before delivery. Generally, the aging time of the module is 24 hours, and the aging time of the box is 72 hours. Of course, if customers don't rush to ship, they can age for a longer time. During the aging process, the LED display manufacturer will designate QC to check. If any fault is found, the manufacturer will notify the technician to repair it, so as to ensure that the customer can get high-quality products.

Of course, it is possible that the LED display may fail during the customer's use, which requires the LED display manufacturer to send technicians for maintenance. In addition, after the installation of the LED electronic large screen is completed, the LED display manufacturer's technicians are required to check whether the waterproof, heat dissipation, surface waterproof coating, power supply line, the rainproof range above the display screen and the heat dissipation on both sides of the display screen meet the requirements. If not, maintenance is required.

The above is the brief introduction of LED display manufacturers about the points that need attention before and after the installation of LED display. It includes field investigation, installation, luminous radiation commissioning, inspection and maintenance. Both LED indoor display and LED outdoor display should pay attention to product quality and performance, otherwise they are prone to failure during use. The process of LED outdoor display screen is more complicated than indoor display screen, whether in installation or production.
