The concept of a large outdoor screen
As the name implies, a large outdoor screen is brighter than a normal LCD screen. Ordinary LCDs have a maximum brightness of 500nits or less, and the backlighting is CCFL, which makes it impossible to see clearly outdoors.
The reason why outdoor high brightness LCD screen can be used in the outdoor, the principle is to improve its backlight luminous brightness, the use of LED backlight, and outdoor brightness is similar or even higher than the outdoor brightness, generally need to be higher than 500nits, some of the highest can even reach 2000nits brightness, so that the outdoor LCD screen can be more clear display.
Secondly, due to the variability of the outdoor environment, to ensure that the screen can operate normally in a variety of environmental conditions without hindrance, outdoor high brightness screen must also have wide temperature, dustproof, waterproof and many other functions.
