Common Misconceptions About LED Displays Do Indoor Displays Also Need Waterproofing

16 views admin 2025-08-14

There are many misconceptions regarding the question of whether indoor LED displays require waterproofing. The following detailed analysis combines the operating environment and characteristics of LED displays

I. Core Conclusion Indoor displays generally do not require strict waterproofing. The core characteristics of an indoor environment are no direct rain, no long-term water accumulation, and relatively stable humidity. However, the waterproofing requirements for LED displays primarily target direct liquid intrusion (such as rain, splashing, and immersion). Therefore, the design focus for indoor displays is not on waterproofing rating, but rather on moisture and dust resistance.

II. Common Misconceptions Misconception The higher the waterproofing rating, the better the screen quality.

Waterproofing ratings (such as IP65 and IP68) are standards for protection against external liquid intrusion and are primarily applicable to outdoor displays (which must withstand rain, dew, and other water damage). Forcing a high waterproof rating for indoor screens may actually lead to drawbacks

Increased costs Waterproof structures (such as sealants and waterproof frames) increase production and maintenance costs;

Impacting heat dissipation Tight sealing can hinder heat dissipation within the screen, potentially accelerating component aging.

While small amounts of liquid contact (such as spilled beverages) may occur indoors, these situations are considered incidental, small-scale contact rather than long-term or large-scale water intrusion. High-quality indoor screens are typically designed with basic splash resistance (such as a waterproof film on the surface and simple sealing of joints), which is sufficient to withstand daily accidents and does not require professional waterproofing ratings of IP65 or higher.

The core issue in humid environments is condensation (which can cause circuit shorts), not liquid water. In these situations, the screen's moisture resistance and heat dissipation design (such as using moisture-resistant components and enhancing ventilation and heat dissipation) should be prioritized rather than the waterproof rating. Excessive sealing can trap moisture inside, exacerbating the effects of humidity.

Third, in summary Indoor LED screens don't require stringent waterproof ratings. Excessive waterproofing can actually affect performance and lifespan.

When selecting an indoor screen, pay more attention to heat dissipation, moisture-proof design, dustproof rating (such as IP54, which protects against dust and light water spray), and basic splash-proof treatment on the screen surface.

Outdoor screens, due to their complex environments, require a specific high waterproof rating (such as IP65). The two should not be confused.

Selecting the appropriate protection standard based on the actual usage scenario ensures performance while controlling costs, avoiding the misconception that the higher the waterproof rating, the better.
