FAQs About p3.91 Outdoor LED Display
Yes. Our P3.91 outdoor LED displays are specifically engineered with high-brightness (typically ≥5500 nits) LEDs. This ensures that your content remains perfectly visible and vivid even under direct sunlight, unlike indoor screens which would appear washed out.
The optimal viewing distance is typically 3 to 12 meters. While the minimum viewing distance (where the image looks seamless) is around 3.9 meters, the "sweet spot" for visual impact is generally 10-12 meters.
Absolutely. Our P3.91 outdoor units come with an IP65 protection rating, meaning they are fully protected against rain, dust, and moisture. They are designed for 24/7 reliable operation in outdoor weather conditions.
It’s all about the balance. P2.6 is for ultra-close viewing (like high-end conference rooms). P4.81 or P5 are better for long-distance viewing to save costs. P3.91 is the industry standard for "versatility," offering the best balance between high-definition clarity and budget efficiency.
With our modular design and robust components, daily maintenance is not required. We recommend a general inspection every 6 months to check the control system and clean the surface. If you choose our Front Service version, any module replacement can be done in minutes without disassembling the whole screen.
