1. Revolutionary COB Technology
The Seattle conference room required the highest level of visual fidelity. By utilizing COB (Chip-on-Board) technology, the CR-121 provides a seamless, robust surface that is highly resistant to dust and impact (IP54 front rating). The 10000:1 contrast ratio delivers deep blacks and vibrant colors, making it ideal for detailed data presentations.
Key Advantage: COB technology significantly reduces pixel failure rates and provides a much more comfortable viewing experience for long meetings.
2. Ultra-Wide Viewing Angles
In a large executive boardroom, visibility from every seat is paramount. The CR-121 offers an ultra-wide 165°/165° (H/V) viewing angle, ensuring consistent brightness and color accuracy from any corner of the room. Combined with a 3840Hz refresh rate, the display remains flicker-free.
3. Slim Design & Easy Installation
Space efficiency and aesthetics were key for this Seattle project. The 600x337.5x45mm die-cast aluminum cabinets are designed for direct wall mounting. At only 4kg per cabinet, the installation is lightweight yet durable.
- ✔ Front Maintenance: Full front access for modules.
