How to Prevent the "Caterpillar" Failure -- Abnormal-Luminous LED Column Pixels of LED Screens?

Have you ever suffered the following problem when you power on a LED wall that you don’t use for a long time?

"Caterpillar" Failure of LED Walls



This is a string of adjacent lamps that luminize abnormally without control and remain unchanged against the dynamic broadcasting content. It’s like a caterpillar lying on the screen, and therefore it is described as the "caterpillar" phenomenon of LED screens some times. 


So why will these abnormal-luminous LED column pixels happen? Generally speaking, undesirable operation environment like moisture or salt fog will humidify the LED displays. If the lamps or IC components get damp and short-circuited, the lamp column shall stay bright and noticeable all the time. To prevent this problem, dehumidification is the key. Hence, LianTronics has developed Nano Coating Protection Craftsmanship and Intelligent Current Gain Dehumidification Technology to get rid of these LED "caterpillars"! 


LianTronics Nano Coating Protection Craftsmanship is applied under a vacuum plasma environment, where the modules can be coated with macromolecule nano polymer material all around. This nano coating features 20 nanometers only but bring IPX5 high protection for the screen surface, and acts like a protection suit to prevent the display components from reacting with external moisture and corrosion like chemical reagents, salt spray, sulfide, etc. This innovative solution of LianTronics can effectively solve the problems of abnormal-luminous LED column pixels caused by humidity.

Except for the precaution of Nano Coating Craftsmanship, LianTronics Intelligent Current Gain Dehumidification Technology can also prevents the occurrence of “caterpillars” during daily use of the LED screens. Based on the measurement of a variety of complex environments and the unused duration of the LED wall, three dehumidification modes are set to dehumidify the video wall. Just run the current-gain dehumidification program automatically or manually and easily complete the dehumidification maintenance of your video wall.
