The main application environment of outdoor LED large screens is the harsh environment of wind and rain, which must be resistant to sun and frost. Outdoor LED large screens not only have high requirements for waterproofing, but also have high requirements for dust, moisture, freeze, and low temperature. The following LED Screen Supplier will explain the terms commonly encountered in outdoor LED large screens, I hope to help you.
1. Outdoor LED large screen unit board brightness: When it comes to brightness, we think of the word high brightness, this parameter is a parameter that people pay more attention to. Brightness is a more complex issue in LEDs. The brightness we refer to in LED unit boards is usually the luminous intensity and transparency, and is generally the sum of the degrees associated with each unit board.
2. Outdoor LED large screen unit board size: usually refers to dimensions such as length, width and height. The maximum length of a single connection. This parameter is used more often in large projects. It means the number of connected LED unit boards in a series of LED unit boards. This has something to do with the size of the connecting line of the LED unit board, which must also be customized according to the actual situation.
3. Outdoor LED large screen unit board voltage: It is a very important parameter in LED unit board. At present, 5V low-voltage unit board is more common. When connecting the power supply and the control system, you must check the correctness of the voltage value to power on, otherwise the LED unit board will be damaged.
4. Outdoor LED Display waterproof level: This is mainly for outdoor, it is an important indicator to ensure that the LED unit board can work outdoors for a long time. Generally, the waterproof level of the LED large screen must reach at least IP65 in an outdoor environment.

7. LED large screen light emitting angle: The light emitting angle of the LED unit board without lens is mainly determined by the LED light beads. The different light emitting angles of the LED light beads are also different. Generally, the light emitting angle of the LED light beads provided by LED large screen manufacturers is Light emitting angle of the LED unit board.
The above are common professional terms about outdoor LED large screens, I hope to help everyone.
