What is NPQD® technology in the QDCOB Series?

NPQD® (Nano Pores Quantum Dot) technology forms nano-pores inside the GaN LED chip and fills them with selected quantum dots. Blue light excites the quantum dots to generate pure red and green light, creating a monolithic RGB LED structure with higher color accuracy, wider color gamut, and better long-term stability.

How does the QDCOB Series improve color performance?

Unlike conventional LED displays, the QDCOB Series uses NPQD® quantum dot technology to deliver richer colors, higher color purity, wider color gamut, and outstanding color consistency across the entire display surface.

Does the QDCOB Series have color shift when viewed from the side?

No. Thanks to NPQD® technology and the COB package structure, the display maintains consistent colors across viewing angles up to 170°, making it ideal for meeting rooms, studios, command centers, and other professional environments.

What pixel pitches are available?

The QDCOB Series supports P0.6 P0.78, P0.9375, P1.25, and P1.5625, providing ultra-high resolution for close-viewing applications including control rooms, XR production, broadcast studios, and executive meeting spaces.

Does the QDCOB Series support front maintenance?

Yes. The display features magnetic full front maintenance, allowing modules, power supplies, and receiving cards to be serviced entirely from the front, making it ideal for wall-mounted installations.

What display performance does the QDCOB Series provide?

The QDCOB Series supports 3840Hz and 7680Hz refresh rates, 16-bit grayscale, brightness up to 1200 nits, and a 170° ultra-wide viewing angle, delivering smooth images and excellent visual performance for professional indoor applications.

Where is the QDCOB Series commonly used?

It is widely used in command centers, security monitoring rooms, XR virtual production, broadcast studios, conference rooms, corporate lobbies, museums, medical visualization, education, and premium commercial display projects where exceptional color accuracy is essential.

Why choose the DDW QDCOB Series instead of a conventional COB LED display?

The DDW QDCOB Series combines proprietary NPQD® quantum dot technology, monolithic RGB color generation, 170° no color shift, wider color gamut, magnetic front maintenance, 16:9 lightweight cabinets, P0.78–P1.56 pixel pitches, 3840Hz/7680Hz refresh rates, and energy-efficient operation to deliver superior image quality for mission-critical visualization and premium indoor LED projects.
