LED display how to prevent static electricity
In the process of using the LED display, there will be dead lights or no light. This is mostly caused by static electricity. How does the LED display prevent static electricity?
The harm of static electricity in the production process of LED display screen If it ignores anti-static at any stage of production, it will cause the electronic equipment to malfunction or even damage it. When semiconductor devices are placed alone or loaded into a circuit, permanent damage to these devices may occur due to static electricity even if power is not applied. As we all know, LED is a semiconductor product. If the voltage between two pins or more pins of the LED exceeds the breakdown strength of the component medium, it will cause damage to the component. The thinner the oxide layer, the greater the sensitivity of the LED and the driver IC to static electricity, such as the lack of solder, the quality of the solder itself, etc., which can cause serious leakage paths and cause devastating damage.
How to prevent static electricity on LED display:
1) Training of static electricity knowledge and related technologies for personnel using static sensitive circuits.
2) Establish an anti-static work area, use static-discharge floor, anti-static workbench, anti-static grounding lead and anti-static device in the area, and control the relative humidity to 40 or above.
3) The damage caused by static electricity to electronic equipment may be released anywhere from the manufacturer to the field equipment. The hazard is caused by insufficient, effective training and malfunction of equipment handling. LEDs are devices that are sensitive to static electricity. INGAN wafers are generally considered to be "first" susceptible to interference. And ALINGAPLEDSSHI "second place" or better.
4) ESD damaged devices can show dim, blur, extinction, short or low VF or VR. Equipment damaged by ESD should not be confused with electronic overload, such as: incorrect current design or drive, wafer attachment, wire shield grounding or packaging, or common environmental induced pressure.
5) ESD safety and control procedures: Most electronic and electro-optical companies have very similar ESDs and have successfully implemented ESD control, manipulation and main programs. These programs have been used to detect quality effects because of ESD. ISO-9000 certification also included him in the normal control program.
