Excessive temperature will cause the LED display to be completely destroyed
(1) LED display operating temperature exceeds the chip carrying temperature will make the LED display luminous efficiency quickly reduced, resulting in significant light failure, and cause damage;
(2) LED display is more transparent epoxy resin package, if the junction temperature exceeds the solid phase transition temperature (usually 125 ℃), the packaging material will change to the rubber and thermal expansion coefficient soared, resulting in LED display open and failure The
Temperature rise will shorten the life of the LED display
LED display life for its light failure, that is, a long time, the brightness is getting lower and lower until the last extinguished. Often the definition of the LED display luminous flux decay 30 for its life.
Excessive temperature limits the maximum injection current of the LED display
