With the rapid development of display technology, full-color LED displays are widely used in many indoor and outdoor scenes. Although they are both based on LED technology, due to the completely different usage environments, outdoor full-color LED displays and indoor full-color LED displays are different. There are a number of significant differences.

1. Brightness requirements

Indoor full-color LED displays are mainly used in indoor environments where light is relatively controllable, such as shopping malls, conference rooms, exhibition halls, etc. Even in indoor areas with good lighting, the ambient light intensity is limited. Therefore, its brightness is generally between 800 - 2000 cd/㎡, which can ensure a clear and eye-catching display effect. Too high brightness may cause visual discomfort.

In contrast, outdoor full-color LED displays face strong direct sunlight and complex and changeable natural light conditions. In outdoor places such as squares, streets, and stadium facades, the light intensity is extremely high. To ensure that the image remains clearly visible under strong light, the brightness of outdoor screens usually needs to reach 5000 - 10000 cd/㎡ or even higher to counteract strong ambient light interference.

2. Protection performance

The indoor environment is relatively stable and mild, without being affected by harsh climatic factors such as wind, rain, sun, sand and dust. Therefore, the protection design of indoor full-color LED display screens focuses on dust prevention and heat dissipation. Generally, a conventional dustproof shell is used to ensure the normal operation of internal electronic components and maintain a suitable working temperature through a reasonable heat dissipation structure.

Outdoor full-color LED display screens have to face the test of nature and must have multiple protection capabilities such as excellent waterproof, dustproof, moisture-proof, UV-proof, windproof, and earthquake-resistant. The housing is usually made of high-strength, corrosion-resistant materials, with a protection level of IP65 or even higher. It is equipped with sealing strips, waterproof breathable valves and other accessories to ensure that the display can continue to operate in extreme weather such as heavy rain, heavy snow, and strong sandstorms. Stable job.

3. Pixel Pitch

The indoor viewing distance is relatively close, and the audience has higher requirements for picture fineness. Indoor full-color LED displays often use smaller pixel pitches, such as P1.2, P1.5, P1.8, P2.5 and other specifications, which can present delicate and clear images and texts at close range, meeting the needs of command and control. Control centers, high-end exhibition halls and other scenarios with demanding requirements on details.

The outdoor viewing distance is far, and the larger pixel pitch does not affect the audience's perception of the overall picture. Therefore, the pixel pitch of outdoor full-color LED display screens is relatively large, and the common ones are P4, P5, P6, P8, P10, etc., which can effectively control costs while ensuring long-distance visibility. It is suitable for large-scale outdoor advertising, sports Long-distance viewing scenes such as event big screens.

4. Display content and refresh rate

Indoor full-color LED displays are mostly used to display relatively static or dynamic content with relatively slow changes, such as corporate promotional videos, product displays, conference materials, etc., and the refresh rate requirements are relatively less extreme. Generally, a refresh rate of 30-60 Hz is sufficient. It can meet daily use and ensure smooth images without obvious ghosting.

Outdoor full-color LED displays often play high-speed sports advertisements, live sports events, and other content. When viewers quickly scan the screen from a distance, a high refresh rate can ensure the stability and smoothness of the picture, avoiding freezes, flickers, or ghosting. Phenomenon, so its refresh rate requirement is relatively high, mostly above 1000 Hz, so that outdoor audiences can enjoy a clear and dynamic visual feast.

5. Difficulty of installation and maintenance

The indoor full-color LED display has a relatively convenient installation environment, a relatively regular space, a variety of installation methods and relatively simple operation. You can flexibly choose wall-mounted, suspended, embedded, etc. according to the indoor layout. Daily maintenance is also relatively easy, troubleshooting is easy, module replacement is convenient, and maintenance work is basically not restricted by the external environment.

The installation site for outdoor full-color LED display screens is complex and often requires high-altitude operations. It faces special installation locations such as building facades, light poles, and rooftops, making installation difficult and risky. At the same time, maintenance is severely affected by external factors such as weather and traffic. Regular inspections, cleaning, and fault repairs require overcoming many inconveniences, and place extremely high demands on the professional capabilities and safety measures of technicians.

6. Cost Considerations

Indoor full-color LED display screens do not require super strong protection, have moderate brightness requirements, and have small pixel pitch, so they are relatively low in terms of material costs and power consumption costs. At the same time, the installation and maintenance costs are not high, and the overall cost is relatively controllable, making it suitable for large-scale popularization in various indoor places.

Outdoor full-color LED displays have high standards for brightness, protection performance, and long-distance visibility, which leads to high costs for core components such as luminous materials, protective shells, and high refresh rate driver chips. In addition, the installation is complex and the maintenance cost is high. The overall investment cost is much higher than that of indoor screens, but with its strong outdoor adaptability, it plays an irreplaceable role in the fields of city image display and commercial advertising.

In summary, outdoor full-color LED display screens and indoor full-color LED display screens have obvious differences in brightness, protection, pixel pitch, content display, installation and maintenance, and cost according to their respective usage scenarios. Users should consider the following when choosing. Fully consider actual needs, weigh the pros and cons, and select the most suitable display product.
