From the environmental aspect indoor LED display is much better than outdoor environment, not affected by high temperature, no special requirements for waterproof. Indoor LED displays have high requirements for air humidity. In southern China, ventilation measures need to be strengthened to maintain a dry environment in front and behind indoor LED screens.

Indoor LED displays are usually hung on the wall, some at a distance from the wall. For example, the stage LED screen will have a safe passage behind the stage and will be hoisted for special scenes. For example, indoor LED displays will be hoisted in the center of a sports arena or in the center of a large shopping mall, with various installation methods requiring special protection and maintenance.

Indoor LED displays are maintained in two ways. Common hanging walls usually use a pre-maintenance structure to facilitate installation and later maintenance. By removing the screen artifact, the front of the LED module, such as the power supply and control system, can be removed. If the indoor LED display adopts the post-maintenance method, technical personnel need to operate and maintain the LED display. This method requires a maintenance channel to be reserved behind the LED display.
