What is the difference between LED transparent screen and LED grille screen? 1 Use lamp beads different: LED light bar screens are generally large, so the point spacing is relatively large, and the density density is relatively small, but it requires highlighting products in the outdoor environment. Come to ensure the highlighting characteristics of the screen body. The LED transparent screen is installed in the indoor installation. The density is generally relatively large, the point spacing is relatively small, and the precision is higher, so it is generally made of SMD lamp beads. 2 The installation environment is different: The LED grille screen is installed outside the screen, and the transparent LED display can also be installed in the indoor environment. 3 Different waterproof grades: LED grille curtain display are installed in a pure outdoor environment, so the level characteristics of the high defense of the outdoor LED display screen are continued. Generally, the protection level needs to reach IP65. The protection level is not high. Generally, it is in IP34. Unless the position of the glass boardwalk is used, nano protection must be performed to improve the protection level.
