In the LED display product performance parameters, many people are more concerned about the display color, brightness, chip, power supply, IC and other issues, but very few people to pay attention to the anti-static properties of LED display. The impact of static electricity on electronic products is very large, sometimes even fatal, the following LCF editorial and we come together to discuss the knowledge of anti-static.

 

LED display


First, the source of static electricity: the circuit has an impact on the source of static electricity mainly human body, plastic products and related equipment and instruments, which comes from the use of environmental sources of static electricity including objects, materials; floor, work tables and chairs; work clothes, packaging containers; painted or waxed surfaces, organic and fiberglass materials; concrete floors, painted or waxed floors, plastic tiles or flooring leather; synthetic fiber coveralls, non-conductive work shoes, and Clean cotton coveralls; plastics, boxes, bins, bags, trays, Styrofoam liners.

 

Second, electrostatic discharge failure: sudden failure and potential failure. In the use of electrostatic failure in the environment of more than 90 for the potential failure, manifested in the circuit of the anti-electrical overstress ability to weaken, shorten the service life.

 

Third, anti-static measures: the use of electrostatic sensitive circuits for personnel to carry out electrostatic knowledge and training of relevant technology; the establishment of anti-static work area, the use of anti-static floor, anti-static workbench, anti-static grounding leads and anti-static appliances in the area, and the go to the relative humidity control in more than 40; electrostatic hazards caused by electronic equipment may be discharged from the manufacturer of the equipment to the field anywhere. Hazards are caused by inadequate, effective training and equipment manipulation failures. LEDs are static-sensitive devices. ingan wafers are often considered the “first” to be susceptible to interference. While ALINGAPLEDSSHI is “second” or better; ESD-damaged devices can exhibit dim, fuzzy, off, short or low VF or VR. ESD-damaged devices should not be confused with electronic overloads such as those caused by faulty current design or drive, wafer tapping, wire shield grounding or encapsulation, or common environmental induced stresses. or ordinary environmentally induced stress, etc.; ESD Safety and Control Programs: Most electronic and electro-optical companies are very similar to ESD and have successfully implemented ESD control, manipulation, and master programs for so devices. These procedures because ESD has been used in the distant past to detect the quality effect of the instrument. ISO-9000 certification also listed him as normal control procedures.

 

Transportation and encapsulation: In daily operation, ESD-sensitive equipment should always be stored in anti-static bags or containers. This includes a detailed catalog of reserves, transportation and WIP. prevention during transportation includes the consumption of fleet, box or other equipment, such as with conductive wheels or drag even, in the delivery of ESD equipment is grounded; LED display is the most widely used display products on the market in the large screen applications, because of belonging to the high-end display products, the production cost is relatively high, the LED display manufacturers need to carry out on the company's employees Anti-static knowledge training, while the relative humidity control above 40, as far as possible to reduce the LED display in the transportation process damage rate.

 

Mastery of anti-static knowledge, help to improve the production efficiency of LED display products, but also reduce the occurrence of safety accidents.
