Differences between outdoor and semi-outdoor LED displays
Outdoor and semi-outdoor LED displays have distinct differences primarily in three aspects: pixel pitch, brightness, and manufacturing process.
1. Pixel Pitch
Pixel pitch refers to the distance between the centers of two adjacent pixels on an LED display. It is a crucial factor in determining the display's clarity.
- Outdoor LED displays typically have larger pixel pitches (P5 and above) due to the longer viewing distances in outdoor public spaces, such as squares, stations, and shopping mall exteriors.
- Semi-outdoor LED displays are often used indoors or in partially covered environments like shopping mall atriums, hotels, and office buildings. They generally have smaller pixel pitches (P2 to P5) to provide more detailed and realistic images for closer viewing distances.
2. Brightness
- Outdoor LED displays require extremely high brightness (usually 2000cd/m² or more) to ensure clear visibility in various lighting conditions, including direct sunlight and overcast weather.
- Semi-outdoor LED displays have lower brightness requirements (typically 500 to 1500cd/m²) due to their less demanding environments.
3. Manufacturing Process
- Outdoor LED displays undergo more complex manufacturing processes to ensure water resistance, moisture resistance, and dust resistance. They often require special sealing and protective treatments to withstand harsh outdoor conditions.
- Semi-outdoor LED displays have simpler manufacturing processes and lower costs due to the less demanding environmental requirements.
In conclusion, the primary differences between outdoor and semi-outdoor LED displays lie in their pixel pitch, brightness, and manufacturing process. These differences result in distinct characteristics in terms of application scenarios, display effects, and lifespan. Therefore, when selecting an LED display, it is essential to consider the specific needs and usage environment to choose the most suitable product.
