In the rapidly evolving world of commercial displays, the shift from traditional SMD (Surface Mounted Device) to COB (Chip on Board) technology marks a significant leap in both performance and reliability. At PRIMA, we have integrated this cutting-edge innovation into our flagship 135" All-in-One LED Display to redefine what professionals expect from a large-scale screen.

1. A Visual & Interactive Masterpiece

The first thing you notice about the PRIMA 135" COB display is its breathtaking clarity. Designed for high-end boardrooms and command centers, it offers a visual experience that traditional displays simply cannot match.

• Exceptional Contrast: With a 6000:1 contrast ratio, it delivers deep, pure blacks and brilliant whites for stunning image depth.

• High Brightness: Reaching 600 nits, the display ensures "Bright Light Readability," making content clear and vibrant even in sunlit environments.

• Smart Interaction: Powered by Android 15.0 and featuring 10-point infrared multi-touch, the 135-inch canvas becomes a collaborative powerhouse, allowing for smooth, intuitive presentations.

2. Engineered for Longevity and Reliability

While the visuals capture your attention, the engineering behind the panel ensures your investment is protected for years to come. The PRIMA COB series is not just a screen; it is a durable asset.

• Extended Lifespan: Our LED modules are rated for a lifespan of ≥100,000 hours, ensuring long-term operational reliability for your organization.

• Certified Stability: This product has successfully passed rigorous high/low temperature and humidity cycle tests. Whether in a climate-controlled office or a more demanding industrial environment, it delivers stable performance without compromise.

3. The "Triple Protection" Advantage

The true secret of COB technology lies in its physical structure. Unlike SMD LEDs where pixels are exposed, COB technology encases the LEDs in a protective layer, providing a "shield" against common workplace hazards.

• Impact/Armor Resistance: The screen is built to withstand physical contact and accidental bumps, making it ideal for high-traffic areas and interactive education settings.

• Water & Dust Resistance: The sealed surface prevents moisture and dust from reaching the delicate electronics, significantly reducing maintenance needs.

• Anti-Static Protection: Advanced materials mitigate the risk of static interference, ensuring a flicker-free, consistent viewing experience.

Conclusion: The Professional Standard

The PRIMA 135" COB All-in-One LED Display is more than just a big screen; it is a smart, resilient solution designed for the modern era of communication. By combining the interactive power of Android 15.0 with the physical toughness of COB packaging, we provide a tool that drives both engagement and peace of mind.
