large video walls: The key process of LED display
Display circuit board and main plug-in production and assembly process
The circuit board is strictly treated with “three defenses” to ensure that the entire circuit system has good waterproof and anti-corrosion functions, and can ensure normal work in humid and special environments. The main connectors are made of high-quality gold-plated devices to ensure good electrical connection performance of the system in high temperature and high humidity environments. Ensure that the cooling system is sound and ensure the safety and reliability of the system.
Large-screen LED display module production and assembly process
The module is packaged with a single lamp, and the front is potted with protective glue, which can effectively protect the single lamp. The circuit on the back of the module and its driving circuit are painted with three-proof paint. On the joint surface of the module and the box, each module is equipped with a rubber sealing gasket. In the process of module and box assembly, apply special waterproof glue. Module replacement can be done directly on the screen without external assistance.
Large-video walls box production and assembly process
During the processing of the box, the metal surface is cleaned and sandblasted to remove rust; the metal surface is oxidized and galvanized to prevent surface oxidation and corrosion; Effectively prevent the erosion of acid rain fog.
During the assembly process of the cabinet, a special waterproof sealant is applied between the two cabinets, which can effectively prevent external rainwater, dust, etc. from entering the screen, causing the internal environment to be unclean.
The box body is equipped with a back cover and an axial flow fan, so that the box body has a good air duct design, which can achieve better heat dissipation effect. The upper part of the box is equipped with an AC axial flow fan, which exhausts air to the outside, increases the flow speed of the air in the box, and realizes effective ventilation and heat dissipation. In addition, the air inlet (installed with a filter) and the air outlet are in the form of waterproof shields, which play the role of dustproof and waterproof under the condition of ensuring good heat dissipation, so that the electronic components can work normally under better conditions.
The box body and the grounding of the power supply are connected by wires, and are connected to the earth through the large screen screen structure, so as to ensure a good grounding and prevent the screen body from being electrified. The display screen is composed of independent boxes, and the independent boxes are waterproof, dust-proof, anti-corrosion and anti-static.
The box unit power supply adopts an independent box unit power supply design: the power supplies between each box are independent of each other, and the box adopts a high-efficiency switching power supply with overvoltage and overcurrent protection functions, reducing power consumption and protecting electronic components. If the local power supply is damaged or abnormal, it will not affect the use of the entire screen, and the user only needs to replace the local power supply, which can make maintenance easier and more convenient.
LED electronic display screen structure
Large-screen led screen structure: using steel unit box, using modular, seamless splicing method, fully equipped with rain-proof structure, dust-proof structure, shock-proof structure, anti-static measures, air-cooled heat dissipation system and other functions to ensure the screen The safety and stability of the body are realized, the structure is moisture-proof and anti-corrosion, and it can be used in a temperature environment of -10°C ~ +50°C. There is maintenance space behind the screen, which is convenient for installation and maintenance.
