The distinguishing characteristics of indoor and outdoor LED displays

Publish Time: 2024-11-25
Today, with the rapid development of digital display technology, LED displays have been widely used in various indoor and outdoor occasions, from commercial advertising to conference displays, from sports events to public information release, everywhere. However, there are significant differences in design and performance between indoor and outdoor LED displays to adapt to different environments and application needs.


1. Brightness

Outdoor LED display: Brightness is its most significant feature, usually between 5000 - 8000nits or even higher. This is because the outdoor ambient light is complex and changeable, including strong direct sunlight and reflected light from buildings. The high brightness ensures that even under sunlight, the screen content is still clearly visible without interference from strong light.

Indoor LED display: The brightness is relatively low, generally around 800-2000nits. The indoor ambient light is dark and stable. Excessive brightness will cause eye discomfort to the audience, causing problems such as glare and visual fatigue. Therefore, indoor LED displays pay more attention to the balance between brightness and comfort.

2. Contrast

Outdoor LED display: The contrast ratio is generally between 1500:1 - 5000:1. Despite the large interference from outside light, through special technology and materials, outdoor LED displays can still maintain the visibility and layering of the picture under strong light. High contrast helps viewers distinguish the subject and background in the picture when viewing from a distance.

Indoor LED display: The contrast ratio is relatively high, usually reaching 3000:1 - 10000:1. Stable indoor light and low ambient light interference allow the display to present more delicate picture details and color transitions. High contrast enhances the clarity, vividness and detail of images, enhancing the viewer's visual experience.

3. Pixel spacing

Outdoor LED display: The pixel pitch is relatively large, and the common ones are P4, P5, P6, P8, P10, etc. This is because the outdoor viewing distance is longer and the larger pixel spacing will not affect the visual effect and can also reduce costs.

Indoor LED display: small pixel pitch, such as P1.2, P1.5, P1.8, P2, etc. Indoor viewing distance is closer, requiring higher pixel density to ensure the clarity and detail of the picture.

4. Protection level

Outdoor LED display: high protection level requirements, generally IP65 or above. This means the display is completely dust-proof and protected from water jets. The high protection level helps resist the erosion of the display screen by harsh natural environmental factors such as rain, dust, and sand.

Indoor LED display: The protection level is low, usually around IP30-IP40. The indoor environment is relatively clean and dry, and the protection requirements for the display are low.

5. Refresh rate

Outdoor LED display: The refresh rate is generally between 1000Hz - 3840Hz. The high refresh rate helps reduce flickering and scan lines, ensuring clearly visible images even in extreme conditions. Especially when playing high-speed sports events, the high refresh rate allows the audience to clearly see the movements of the athletes.

Indoor LED displays: Refresh rate is equally important, but is usually kept at a higher level of 3840Hz (note: 3840Hz here is a specific example and may vary in actual applications). A high refresh rate can provide a smoother visual experience and reduce smearing, and is suitable for playing dynamic videos, game screens and other content.

6. Wide viewing angle and heat dissipation requirements

Wide viewing angle: Outdoor LED displays require a wider viewing angle to accommodate viewers' viewing needs from various positions and reduce reflections; while indoor LED displays generally do not require a very wide viewing angle because the audience is relatively close.

Heat dissipation requirements: Outdoor LED displays have high heat dissipation requirements because they are exposed to the sun for a long time and work at high brightness, so they need to be equipped with large heat dissipation devices; indoor LED displays have relatively low heat dissipation requirements because of their stable environment and low brightness.

7. Price

Outdoor LED display: The price is relatively high, which is closely related to its high brightness, high protection level, large size and other characteristics. At the same time, installation and maintenance costs are also higher.

Indoor LED display: The price is relatively low because it has low requirements for brightness, protection, etc., and the pixel spacing is small but the size is generally small, and the cost of materials and manufacturing processes is relatively low.


There are significant differences between indoor and outdoor LED displays in many aspects to adapt to different application environments and needs. When choosing an LED display screen, comprehensive considerations should be made based on the specific application scenario and budget to ensure that the most suitable display product is purchased.
