8. Dehumidification function
Purpose of dehumidification in LED display
Internal parts and elements tend to corrode during storage when the LED display is left unused for a long period of time in a
humid environment. In particular when moisture gets into the diode, it may cause blurred screen or defective LED. As a result, the
dehumidification has an important role to play in the performance and lifespan of LED display.
Principles of dehumidification
Configuring LED display controller settings allows the display to change the brightness level from low to high during boot up
process. Likewise, the heat generated in the fade up process can take moisture out of the LED display. A stepwise fade up process
can avoid impulse current caused by damp diode when booting up the display.
