In the performance parameters of LED display products, many people pay more attention to the color, brightness, chip and other issues of the display, but few people pay attention to the anti-static performance of the LED display. Static electricity has a great impact on electronic products, sometimes even It is fatal, let's discuss with you the knowledge related to anti-static LED display!
One, the source of static electricity
The sources of static electricity that affect the circuit are mainly the human body, plastic products and related equipment and instruments. The static source from the environment of use includes objects and materials; floors, work tables and chairs; work clothes, packaging containers; painted or waxed surfaces , Organic and glass fiber materials; cement floors, painted or waxed floors, plastic floor tiles or floor leather; chemical fiber work clothes, non-conductive work shoes, clean cotton work clothes; plastic, packaging boxes, boxes, bags, trays, foam linings pad.
Two, the failure of electrostatic discharge
Sudden failure and potential failure. In the use environment, the static failure of more than 90 is a potential failure, which is manifested as the weakening of the circuit's anti-electric overstress ability and shortening the service life.
Three, anti-static measures
Train people who use electrostatic sensitive circuits on electrostatic knowledge and related technologies; establish an anti-static work area. LED is a device sensitive to static electricity. INGAN chips are generally regarded as the 'first place' susceptible to interference. And ALINGAPLEDSSHI 'second place' or better; ESD damaged equipment can show dim, fuzzy, extinguished, short or low VF or VR. ESD damaged equipment should not be confused with electronic overload, such as: due to wrong current design or drive, chip mounting, wire shielding grounding or packaging, or ordinary environmental induced pressure, etc.; ESD safety and control procedures: most The ESD of electronic and electro-optical companies is very similar, and has successfully implemented the ESD control, manipulation and main program of all equipment. These procedures have been used as instruments for testing quality effects because of ESD ancient times. ISO-9000 certification also lists him as a normal control procedure.
Fourth, transportation and packaging
In daily operations, ESD sensitive equipment should always be stored in an anti-static bag or container. This includes inventory storage, shipping and WIP. Precautions during transportation include consumable fleets, boxes or other equipment, such as conductive wheels or drag links, and grounding when transporting ESD equipment; LED displays are currently the most widely used display products for large screens on the market, because It is a high-end display product, and the production cost is relatively high. LED display manufacturers need to train their employees on anti-static knowledge, and at the same time control the relative humidity above 40, to minimize the damage rate of the LED display during transportation.
