In the process of LED display production, aging test is an indispensable part for LED displays, but hardly get a mention by purchaser. Here I’m going to give a simple introduction about it.
Aging test of LED display refers to in an imitating test environment, to show whether the abnormal phenomenon of the LED display will occur when it work in a long operating time, it’s an important step to ensure the reliability of the LED display screen and essential for quality inspection and quality guarantee. After aging, the efficiency and the stability of the LED display can enhance in further use.
The aging test contains two parts: LED module aging and the whole LED display screen aging.
1. LED module agingLED modules cannot be used directly after they are produced; aging is the last necessary step. The modules are aging in a sealed room which the constant temperature is 45℃, this will last 24 hours during aging.

2. LED display agingThe whole LED display aging will last 48 hours, during this time the electricity supply shouldn’t cut off. Aging of the entire screen for a total of 48 hours, including 24 hours of white screen aging, which means the LED display screens are showing white color all the time during the aging; and the remaining 24 hours of video aging, during this time the LED displays are playing non-stop video, in order to ensure the display screens have no problems before shipment.
