LED display is promising because of its energy conservation, environmental friendliness and long service life. However, temperature is of great importance to LED screen. Temperature could shorten the life span of LED screen, decrease its light efficiency, set its color at variance and so on. Therefore, proper working temperature is vital to LED screen. Five Impacts Temperature Has on LED Screen 1. Overtemperature Devastates LED display 1) When the working temperature is far higher than what the chips can bear, the light efficiency would decrease rapidly, which would lead to obvious luminous attenuation. 2) LED is usually packed with transparent epoxy. If the junction temperature is higher than the liquid-solid phase transition temperature(usually 125 ℃), the packing materials would become rubber-like with a surge in thermal expansivity, which would lead to open circuit and LED failure. 2. Overtemperature Shortens the Life Span of LED Display The life span of LED ...
