1. exactly where will probably be the LED show installed? indoor or outdoor?
two. what message content is necessary? videos, photos, or simply characters?
3. what dimension will likely be your screen? width, height?
4. what is going to be the minimal viewing distance from your screen to the closest spectators?
five. what's the distance from LED screen to manage technique?
six. what is the installation type? inlay, pole, or something else?
