What should I pay attention to when buying an LED display?

1. It should be clear whether to use an indoor LED display or an outdoor display. The indoor LED screen is not waterproof, and the outdoor large screen is waterproof.
2. It should be clear about the size of the display screen, that is, the length and height of the electronic screen. Measure the viewing distance again, that is, the closest and farthest viewing distance from the display screen.
3. Select the corresponding model and parameter configuration to meet your own needs. With the above three data, you can roughly know what kind of LED display meets the requirements.
