Customers often ask us whether indoor and outdoor LED displays are waterproof. This has made us quite puzzled. In people's minds, outdoor LED displays are definitely required to be waterproof, but indoor displays are not necessarily so. So how do outdoor LED displays achieve waterproofing? Let me introduce it to you in detail.
First, let's distinguish between indoor and outdoor LED displays. Generally, the LED displays used in indoor, semi-outdoor, or protected areas are collectively referred to as non-waterproof indoor environment LED displays. The only difference between outdoor and semi-outdoor is the brightness and the surface protection level of the screen. Due to the factors of the applicable environment, these screens do not need to consider many factors brought by the outdoor environment when it comes to the protection level. The IP protection grades on the back and sides of the screens are relatively low. When choosing the screen, one only needs to select the appropriate pixels based on the budget or viewing distance, brightness, etc.

When choosing outdoor LED displays, the following points must be considered:
1. Brightness: (The luminance of indoor screens is several times to dozens of times lower than that of outdoor screens; placing an indoor display outdoors is like putting a TV outdoors, resulting in insufficient brightness)
What brightness requirements do environmental conditions have for the screen?
The general brightness requirements are as follows:
(1) Indoor: >800CD/m2
(2) Semi-indoor: >2000CD/m2
(3) Outdoor (sitting south facing north): >4000CD/m2
(4) Outdoor (sitting north facing south): >8000CD/m2
2. Environment: Outdoor screens must be protected against rain, direct sunlight, dust, high temperature, wind, and lightning strikes, while indoor screens do not need to consider these issues.
3. Viewing distance: Select different spacing LED displays based on the distance of viewing. This not only allows for better control of brightness but also saves costs and avoids unnecessary waste.
4. What playback effects do users need?
Based on the content you want to play or the playback effect you want to achieve, choose the appropriate LED display for yourself.
(1) Text display: Depending on the size of the text and the resolution requirements;
(2) Ordinary video display: 320×240 dot matrix;
(3) Digital standard DVD display: ≥640×480 dot matrix;
(4) Complete computer video: ≥800×600 dot matrix;
5. Power consumption
Power consumption - This is a concern for many people. The maximum power consumption of full-color outdoor LED displays is approximately 800W/square. That is to say, when this outdoor LED display reaches its maximum power (peak) at all times, the power consumption per square per hour will be 0.8 kilowatt-hours. However, not all times when the LED outdoor display is working will reach the peak, because when all the lights (RGB three-color lights) in the screen are on and are at their brightest, the LED outdoor display will reach the peak. When the outdoor LED display is playing an animation normally, the power consumption is only about 65% of the maximum power consumption. Therefore, the power consumption per square per hour of the outdoor LED display is: 0.8KW*65%=0.52 kilowatt-hours. If calculated for 100 square outdoor LED displays per year (assuming 12 hours of daily playback), the power consumption is: 12*30*12*100*0.52=224,640 kilowatt-hours. Even if the electricity cost is calculated at one yuan per kilowatt-hour, the electricity cost for this outdoor LED display would be around 220,000 yuan. Therefore, choosing a suitable display based on environmental brightness and viewing distance is particularly important for cost control.
