In the novel coronavirus epidemic prevention battle critical juncture, LED shows that the industry and major industries in various regions have also resumed work, many factories, companies and public places are often large-scale disinfection. How to ensure the display effect and quality of LED display products in the production, storage and use environment of epidemic prevention and disinfection?

 First. 84 disinfectant is prohibited to be used for disinfection The disinfection principle of 84 disinfectant containing chlorine and bromine is strong oxidation, with strong corrosiveness and volatility. LED devices (such as lamp beads and chips) have strong reaction to halogen, which has high risk of pollution, metal migration and corrosion. Therefore, 84 disinfectant may cause damage to LED beads, chips, display screens and other supporting devices. 

Second. it is forbidden to wipe LED screen with alcohol It is forbidden to spray or wipe LED display body with ethanol (medical alcohol). On the one hand, the reaction between alcohol and oxygen in the air produces acetic acid, which is weak acid and corrosive, which is not conducive to screen maintenance; on the other hand, alcohol may penetrate into the screen, causing device corrosion and short circuit. 

Third.84 disinfectant and alcohol are not allowed to be mixed If 84 disinfectant is mixed with alcohol, chemical reaction will occur, which will greatly reduce disinfection effect and even produce some organic chlorides. At the same time, 84 disinfectant can not be mixed with other cleaning agents, such as mixing with toilet cleaner with hydrochloric acid, which will generate chlorine gas, which is harmful gas, which is harmful to health, even poisoning, and affects life safety! 

Fourth. the screen body should be protected for disinfection of the environment When spraying disinfectant in the use environment of LED large screen, it is necessary to protect the LED screen body to avoid 84 disinfectant, ethanol (medical alcohol) and other disinfectants spilled on the screen, which will affect the service life and display effect of the screen. During the epidemic, we should pay attention to the protection of LED display products while doing well in disinfection and anti epidemic work, and do not cause more losses due to improper operation.
