What are the hazards of high temperature outdoor LED full-color display? Outdoor full-color LED displays are very picky about the temperature environment. In theory, room temperature around 25 degrees Celsius will work best. But in fact, the temperature of outdoor LED full-color display is quite complicated in application, and the maximum temperature in summer can reach above 60°C. The lowest temperature in winter can be below -20°C. High temperature will cause all the damage to the outdoor full-color LED display. On an outdoor full-color LED display, the life span will be displayed as the light decreases, that is to say, as time goes by, the brightness will become lower and lower, until it finally goes out. Under normal circumstances, the luminous flux decay time of an outdoor full-color LED display refers to its life.

Under normal circumstances, the light attenuation of outdoor full-color LED displays is caused by the following factors:

At high temperatures, the defects in the chip material of the outdoor LED full-color display screen will rapidly multiply and multiply until it invades the light-emitting area, thereby forming a large number of non-radiative composite centers, which seriously affects the luminous efficiency of the outdoor full-color LED display screen. In addition, under high temperature conditions, defects within the material and fast-expanding impurities from the interface and the electric board will also enter the light-emitting area, thereby forming a large number of deep energy levels, and will also accelerate the light attenuation of outdoor LED full-color display devices. Transparent epoxy resin undergoes denaturation and yellowing at high temperatures, which will affect its permeability, and at higher temperatures, this process occurs faster, which is also the main reason for the light attenuation of outdoor LED full-color displays . Due to the severe attenuation of phosphors under higher temperature conditions, the attenuation of phosphors for outdoor LED full-color display screens is also the main reason that affects the light attenuation of LED displays.
