In 2020, public health time broke out. For a time, masks, medical alcohol, 84 disinfectant, etc. were sold out. Strengthening anti-virus and disinfection measures has become an important means for individuals, families, enterprises and institutions to respond.
The necessity of disinfecting the surface of objects. Jiang Rongmeng, a member of the expert group of the National Health and Health Commission, reminded that the virus will quickly settle down after coming out of the human body, and may fall on objects, and people can contact the virus through their hands. The virus can survive for several hours on a smooth surface, and can survive for 1 day in an environment with suitable temperature and humidity, and it can be found to reach 5 days. Therefore, we must pay attention to the regular disinfection of the surface of the object.
As an environment for centralized office and consultation, the command center, especially in the event of a major emergency, the more frequent the exchange of personnel, which will increase the probability of virus transmission. During this period, more attention should be paid to the disinfection of the command center's display and control system.
Some command centers use LED small-pitch display screens. Can we disinfect them with disinfectant?
Is there a difference between the disinfection methods of COB and SMD two small pitch LED screens? Let's take a look at the COB small pitch LED screen first. COB can use the following two methods of disinfection:
First, the surface of the display screen can be directly wiped and disinfected with 75% high-concentration medical alcohol, which will not affect the reliability of the display screen;
Second, the surface of the display screen can be disinfected by spray disinfection with 84 disinfectant (after dilution according to the instructions), and it can be dried with a damp cloth after 10 minutes, which will not affect the reliability of the display screen.
This is decided by the packaging technology of COB small pitch LED screen. The COB display has no problems such as bare lamp legs, the surface is smooth and seamless, wear-resistant and easy to clean, and has excellent performances such as mildew, dust, moisture, corrosion, static, and bump resistance. The COB display screen can prevent the intrusion of water splashed from all directions, etc., which creates conditions for the direct use of alcohol, 84 disinfectant wiping and other spray disinfection methods. The surface of the COB display is easy to clean, which can effectively prevent the deposition of harmful substances such as saliva, aerosol, dust and so on. There is no need to turn off the screen during the disinfection process, coupled with its long service life, to ensure 24 hours of uninterrupted operation of the screen.
However, SMD small-pitch LED screens should be treated with caution. SMD technology does not have the "three-proof" function, the surface is uneven, it may be attached to saliva, aerosol, dust and other harmful substances, not only difficult to wipe directly, the use of (chlorine, bromine) 84 disinfectant, high-efficiency disinfection water, etc. also have great risk. For example, the widely used 84 disinfectant, the main component is sodium hypochlorite, sodium hypochlorite produced hypochlorous acid in the aqueous solution can decompose ecological oxygen, has a very strong oxidizing. If used improperly, it may cause corrosion to the SMD small-pitch LED display screen and its lamp beads with poor protection performance. Based on this, small-pitch LED upstream manufacturers have urgently informed SMD manufacturers to use these disinfectants carefully.
At present, many emergency command centers across the country have undertaken the important task of the joint defense and joint control center. The different types of LED small-pitch screens in the center are sterilized in an appropriate manner to ensure the healthy environment of the command center and the normal operation of the display system. We need to pay attention. In addition, the COB small-pitch LED screen also has the advantages of extremely low cumulative bad spot rate, which can effectively reduce the damage of blue light to the human eye, and is favored by more and more users, and the growth rate is far faster than SMD.
