Why can't indoor LED display be used outdoors?

With the changes of the times, the use of LED display screens is becoming more and more extensive, ranging from shopping malls to company meeting rooms. So the question is, can indoor LED display screens be used outdoors? Why can't they be used? What are the reasons?

1. Viewing distance limit. Indoor LED display screens require a short viewing distance, and the models are generally p2.5, P3, P4, P5, P6, so the area is generally not large, within 30 square meters, while outdoor LED display screens require a longer viewing distance, and the models are generally ph8, P10, P16, P20, etc., so it determines that its area is larger, generally exceeding 30 square meters.

2. Waterproofing limit. The indoor screen structure requires no waterproofing or simple waterproofing, while the outdoor LED full-color display screen has high requirements for waterproofing. The cables and boxes are waterproofed during production, so there are differences in the requirements for the box structure itself.

3. Brightness limit. The indoor LED display screen does not require high brightness, and uses a dynamic scanning circuit. The outdoor screen requires high brightness and is a static scanning circuit. The hardware difference between the two is large. Dynamic scanning is actually used to save hardware costs. The number of driver chips used is more than ten times different, which determines that the brightness of indoor LED full-color display screens is relatively low, generally around 1500cd/㎡, and is only suitable for indoor use. The general brightness of outdoor LED display screens is required to be above 4500 cd/㎡. If this brightness is not reached, the content displayed on the display screen is basically invisible during the day. In a word, the indoor LED screen and the outdoor LED full-color display screen are different in brightness, waterproof treatment, and model selection, resulting in different hardware such as raw materials, accessories, and boxes at the beginning of production, so it is not easy to change, and it will only be more harm than good.

After the explanation of this article, I believe you have an answer to this question.
