LED display anti-static winter required course
Life, the problem of static electricity led display occasional damage. For example, the LED is on the electrostatic body, and one electrode contacts the electrostatic body, the other electrode is just vacant, then someone to touch the suspended electrode, it may damage the LED.

So in the dry season, how full-color LED display anti-static?
To the static on the LED display to minimize the hazards, the need for manufacturers, distributors and customers in the production, transportation and use of strict implementation of the ESD20.20 standard. Directly in the production of static discharge through the wire connection to the earth, which is the most direct and most effective anti-static method.
Static electricity production side prevention
✦ Electrostatic and ESD related knowledge of people using electrostatic sensitive circuits;
✦ During production, workers are required to wear a grounded electrostatic wristband. Especially in the cut feet, plug-ins, debugging and post-welding process, and do a good job monitoring, quality personnel must do at least once every two hours wrist bracelet static test, make a test record;
✦ During soldering, the electric iron should adopt anti-static low-voltage thermostatic soldering iron as far as possible and maintain good grounding;
✦ In the assembly process, as far as possible with a ground wire low voltage DC electric screwdriver (commonly known as electric screwdriver);
✦ to ensure the production of pull table, filling stations, aging shelves and other effective grounding;
✦ Requirements of the production environment to achieve the laying of copper grounding, such as floors, walls, and in some cases the use of the ceiling, etc., should be used anti-static materials. Normally, even normal gypsum board and lime-coated wall surfaces are okay, but plastic ceiling and normal wallpaper or plastic wallpaper are forbidden;
✦ During normal operation, full-color LED display products should always be stored in antistatic bags or containers.
Transport side electrostatic prevention
✦ During transport, the transport vehicle remains grounded, carrying wheels or drag chains with boxes or other equipment;
✦ When touching LED products, keep the correct method of handling, do not touch the PCB board and the above electronic components directly.
Client static electricity prevention
✦ customers and contractors in the installation of the screen body, but also in strict accordance with the anti-static operation, without protection measures do not directly contact the core of the product part of the electronic components;
✦ When installing the screen steel structure, make a good grounding, the screen static electricity into the ground.
