The LED display iReed Electronics guarantees quality measures from material, production and field device commissioning.
First, the key selection process of LED electronic display
Box production assembly process
A special waterproof sealant is applied between the two cabinets during the assembly process. Effectively prevent external rain, dust, etc. from entering the screen, causing the internal environment to be unclean.
The metal exterior is cleaned and blasted, and the casing is processed. The rust-removing effect is exerted; the metal surface is oxidized and galvanized to prevent surface oxidation and corrosion; the exterior paint or the surface is treated with an acid-proof resin to effectively prevent acid rain and fog.
The cabinet has a good air duct design, and the cabinet has a rear cover and an axial fan. A better heat dissipation effect can be achieved. The upper part of the box is equipped with an AC axial flow fan, which exhausts the air to the outside, increases the flow speed of the air inside the box, and achieves effective ventilation and heat dissipation. And the air inlet (the device has a filter net) and the air outlet are in the form of a waterproof shield to ensure dustproof and waterproof function under the condition of good heat dissipation, so that the electronic components work normally under better conditions.
And through the screen structure and the ground connection, the cabinet and the ground of the power supply are connected by wires. This ensures good grounding and prevents the screen from being charged. The display screen consists of separate boxes, which are waterproof, dustproof, anti-corrosive and anti-static.
The box body adopts high-efficiency switching power supply, and the power supply of the box unit adopts independent box unit power supply design: the power sources of each box are independent of each other. With overvoltage and overcurrent protection, reduce power consumption and maintain electronic components. If the local power supply is damaged or abnormal, it does not affect the use of the whole screen. The user only needs to replace the local power supply, which can make the maintenance simpler and more convenient.
Screen structure
Using modular, seamless splicing, LED display body structure: steel unit box. Fully equipped with rainproof structure, dustproof structure, anti-vibration structure, anti-static measures, air-cooling and heat dissipation system, etc., to ensure the safety and stability of the screen body, to achieve structural moisture and corrosion resistance, at -10 °C +50 °C Used in temperature environment. Maintenance space is left behind the screen for easy installation and maintenance.
Module production assembly process
The front side is sealed with protective glue, and the module is packaged in a single lamp. It can effectively protect the single lamp, and the circuit on the back of the module and its driving circuit are painted with three anti-paint. Each module is equipped with a rubber sealing gasket on the joint surface of the module and the cabinet. During the assembly process of the module and the box, a special waterproof glue is applied. Module replacement can be done directly in the screen without the need for off-screen assistance.
Circuit board and main plug-in production assembly process
Ensure that the entire circuit system has good waterproof and anti-corrosion functions, and the circuit board is strictly disposed of by “three defensesâ€. It can guarantee normal work in a humid and special environment. The main connectors are made of high quality gold-plated devices to ensure good electrical connection performance in high temperature and high humidity environments.
Ensure the safety and reliability of the system to ensure the sound system is sound.
Dust prevention measures
Effectively prevent large particles of dust from entering the inside of the cabinet, and the air inlet device filter. Ensure that the electronic components work properly.
Soft start power technology
Prevent large currents from bursting into the power supply system. It is guaranteed to increase the current consumption of the large screen slowly under software control.
Lightning protection measures
The maintenance ground wire in the power distribution system has a resistance to ground of less than 4 ohms.
Second, the quality assurance system
Allied Electronics implements the design, device sales, manufacturing and installation of the display in strict accordance with the ISO9001 standard.
2.1 Scientific rigorous design establishes product reliability
Due to the complexity of the system, the LED display system is a multi-disciplinary and multi-disciplinary combination of TV technology, image processing technology, computer control technology, communication technology, single-chip control technology, integrated circuit technology, power supply and distribution technology. There are many professional fields involved. Therefore, the reliability and stability of the system are also an important aspect that users and designers particularly emphasize.
2.2 Strict design review
Engineering construction and maintenance work instructions, etc., showing the overall scheme of the system, the control system scheme, the screen circuit hardware design scheme, and the structural design scheme. All must be repeatedly demonstrated and reviewed by relevant experts and designers. This includes the use of state-of-the-art, highly reliable circuit modes; thus ensuring effective control of system technical solution reliability during the design phase.
2.3 Strict design, manufacturing, acceptance specifications
