The largest proportion of the LED screen is the LED lamp bead. Therefore, the quality of the LED package device largely determines the quality of the LED display. The high-tech demand of LED display is the future development trend, which is not only related to the trend of LED display manufacturers, but also affects the development of manufacturers during the LED packaging period.


Therefore, from the control of LED packaging devices, to improve the quality of LED displays, and to promote China's transformation from a large LED display manufacturing country to a manufacturing powerhouse.


There are many parameters that determine the quality of LED lamp beads, one of which is very important but easily overlooked, that is, antistatic ability. That is, the resistance of LED lamp beads to static electricity. Because the LED lamp bead is a semiconductor device, it is sensitive to static electricity, and it is very easy to cause static electricity failure. High-quality LED lamp beads can withstand the test voltage of 50Hz, 1500V (effective value of alternating current) for 1 minute without insulation breakdown.


LED is excited by the principle of electron flow, and static electricity has a great influence on electrons, so it cannot effectively resist static electricity, and the light source cannot operate normally or even be put into use. Therefore, the antistatic ability of LED lamp beads is very important for the life of LED display. So what aspects can improve the antistatic ability of LED lamp beads?

1. Chip source

In the process of producing LED lamp beads, there will be a "static crisis" that static electricity will cause damage to the LED chip. Static electricity will cause the PN junction of the LED chip to fail, and the leakage current will increase, turning it into a resistance. Therefore, in the selection of chips, it is necessary to choose a chip with better quality and better effect to reduce the impact of static electricity on the chip.


LCF Group adopts high-quality chips, the quality is guaranteed, and the users are more at ease.


2. Packaging process

The packaging process is also very powerful for the anti-static ability of LED lamp beads. During the packaging process, anti-static clothing should be worn and an electrostatic ring should be worn. The electrostatic ring should be well grounded.


LCF Group adopts a dust-free production workshop, and employees wear anti-static clothing to minimize the impact of static electricity on LED lamp beads.


3. Packaging equipment

In the LED packaging production line, it is also very important whether the grounding resistance of various equipment meets the requirements. Generally, the grounding resistance is required to be 4 ohms. In some cases with high requirements, the grounding resistance is more stringent and even reaches the standard of ≤2 ohms.


LCF Group adopts the most advanced production equipment in the industry and is equipped with sophisticated testing instruments. Before leaving the factory, it strictly controls various parameters of the LED lamp beads to effectively improve the anti-static ability of the lamp beads and ensure the quality of the lamp beads.


Antistatic ability is an ability that LED lamp beads must have. Taking it as the basic LED lamp bead parameter is also necessary to guide the correct application of the light source and protect the light source.


As a professional LED manufacturer, LCF Group keeps improving from the selection of raw materials, packaging equipment, and packaging technology to ensure that the most cost-effective display products are presented to customers, and the product performance is effectively guaranteed and the quality of LED displays is improved.
