The Effect Of Temperature On LED Displays

The influence of temperature on the LED display has the following five points:

First, excessive temperature can cause complete damage to the LED display.

(1) If the operating temperature of the LED display exceeds the bearing temperature of the chip, the luminous efficiency of the LED display will drop rapidly, resulting in obvious light attenuation and damage.

(2) LED displays are mostly encapsulated with transparent epoxy resin. If the junction temperature exceeds the solid phase transition temperature (usually 125), the packaging material will become rubber, and the thermal expansion coefficient will rise sharply, resulting in the failure of the LED display.

Second, elevated temperatures can shorten the lifespan of LED displays.

The lifespan of the LED display is characterized by light decay, that is, the brightness gets lower and lower over time until it finally goes out. Generally, the time when the luminous flux of the LED display screen decays by 30 is defined as its life.
