In LED display product performance parameters, a lot of people are more focus on display color, brightness, chips and other issues, but few people focus on antistatic performance of the LED display, the influence of static electricity for electronic products is very big, sometimes even fatal, below, and everyone together to explore the related knowledge of LED display and anti-static!
1, the source of static electricity
The source of static electricity that affects the circuit mainly includes human body, plastic products and related equipment and instruments.Floor, work table and chair;Work clothes and packaging containers;Paint or waxed surfaces, organic and fiberglass 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, packing box, box, bag, tray, foam liner.
2. Electrostatic discharge failure
Sudden failure and potential failure.Static failure of more than 90 in the service environment is a potential failure, which is manifested as the circuit's ability to withstand electrical overstress is weakened, and the service life is shortened.
3. Anti-static measures
Conduct electrostatic knowledge and relevant technical training for personnel using electrostatic sensitive circuits;Set up antistatic work area.Leds are electrostatic sensitive devices.INGAN chips are generally considered "the first" to be susceptible to interference.ALINGAPLEDSSHI is "second" or better;Damaged ESD devices can display dim, blurry, extinguished, short or low VF or VR.Equipment damaged by ESD shall not be confused with electronic overload, such as: due to wrong current design or drive, wafer mounting, wire shielding grounding or packaging, or common environment-induced pressure;ESD safety and control procedures: ESD of most electronics and electro-optical companies is very similar and has been successfully implemented for all equipment ESD control, manipulation and main procedures.These programs are because ESD has been used since ancient times to detect quality effects of instruments.ISO-9000 certification also lists it as a normal control procedure.
4. Transportation and packaging
ESD sensitive equipment should always be stored in an anti-static bag or container during daily operation.This includes inventory inventory, shipping, and WIP.Precautions during transportation include the consumption of vehicles, boxes or other equipment, such as conductive wheels or towing connections, which are grounded during transportation of ESD equipment;LED screen is the most widely used display product in the market at present, because it is a high-end display product, the production cost is relatively high,LED screen manufacturers need to conduct anti-static knowledge training for the company's employees, at the same time, the relative humidity control at least 40, as far as possible to reduce the damage rate of LED screen in the process of transportation.
