1. Viewing Distance Affects Size Selection

   Indoor LED displays are designed for close viewing distances, typically using models such as P2.5, P3, P4, P5, and P6. These screens are relatively small, usually not exceeding 30 square meters. In contrast, outdoor LED displays are intended for long-distance viewing, using models like P8, P10, P16, and P20. As a result, outdoor screens are generally much larger, often exceeding 30 square meters.

2. Waterproofing Requirements Determine Structural Differences

   Indoor LED displays have minimal waterproofing requirements and may even require no waterproofing or only simple waterproof treatments. However, outdoor LED displays must have high waterproof performance. During production, cables, cabinets, and other components undergo rigorous waterproofing processes, leading to structural differences in the cabinet itself.

3. Brightness Requirements Determine Hardware Configuration

   Indoor LED displays require lower brightness levels, typically around 1500 cd/㎡, suitable for indoor environments. They use dynamic scanning circuits, which require fewer driver chips. On the other hand, outdoor LED displays need much higher brightness, usually exceeding 4500 cd/㎡, to ensure clear visibility in daylight. These displays use static scanning circuits, which involve more driver chips, resulting in higher brightness.

Due to significant differences in model selection, waterproofing requirements, brightness needs, and other factors, the raw materials, components, and cabinet configurations used in the production of indoor and outdoor LED displays are different. Therefore, they cannot be used interchangeably.
