NX-4
The true Black LED display
Key benefits include: · Phenomenal black levels · Contrast ratio of 4000:1 · Brightness output of 2000 Nit · Seamless & lightweight · 16-bit color & grayscales · Consistent uniformity over time · Creativity options · Serviceable without tools
Barco introduces the next breakthrough in LED displays -- the NX-4, the industry's new visual standard in indoor LED technology. With its revolutionary Black LED, the NX-4 delivers the deepest black levels of any product on the market. But the new Black LED is only one element that makes the NX-4 unique. Key advances in base materials, mechanical design and color processing have raised the bar of LED displays to new heights of image quality. NX-4 is not simply an incremental advance in 4mm LED tile technology -- it's more, much more. In fact, the term "quantum leap" doesn't even come close.
The elegant contradiction - black and bright
By far, the key factor that sets the NX-4 apart from all other LED displays is immediately evident -- even when the LEDs are turned off. With the NX-4, Barco has developed a true black LED -- not just a black package, but a radically new design, from the interior resin to the exterior shaders. Using black silicon resin instead of the traditional white epoxy, not only does the NX-4 appear black, but each LED outputs the deepest blacks and brightest luminance levels of any product on the market -- with a phenomenal contrast ratio of 4000:1 and a calibrated light output of 2000 Nit. In addition, NX-4's remarkable output is enhanced by a new "light-trap" shader that combines a super-black shader casting with optimized geometry. The result -- dramatically enhanced horizontal and vertical viewing angles, a significant reduction in light reflections and deeper black levels than ever before. Is "black and bright" a contradiction? Yes -- but a most elegant one, and only from Barco.

Seamless and lightweight
Today's industry standard for mounting an LED wall is metal. While strong and roadworthy, metal frames are heavy, and very sensitive to deformation. To complement NX-4's new LED display benchmark, Barco has engineered the industry's new structural benchmark -- the "Mag-frame". Mag-frame is built of carbon fiber and is designed in a framework -- rather than a box. The result is a support system far stronger, far lighter, and ten times less sensitive to deformation than the current "metal" structures. For added strength and fewer components, the structure uses optimized glue rather than screws, providing extremely tight tolerances along all three structural axes (x, y and z). Not only is carbon fibre incredibly strong, it is also super light. The weight of the NX-4 tile including structure and cables is 59kg/sqm, 21% less than ILite 6XP. For the crew, this translates into significant savings in terms of transportation, serviceability, and far less stress on the overhead truss. Barco has also transformed the entire science of mounting the modules within the tile. With Mag-frame, LED modules connect directly to the structure via high-strength neodymium "neo" magnets, rather than traditional screws. No tools are required for mounting or removal. With each magnet capable of holding over 1000 times its own mass, the result is precise positioning, super easy setup, and a totally seamless display.

Consistent uniformity over time
The NX-4's "black and bright" attributes will revolutionize the display industry, but not if the product's lifetime has to suffer as a result. To address this, Barco has engineered an "anti-aging" solution on three levels:
· By using next generation, highly efficient LED dies and running the LEDs at lower temperatures, extremely high brightness levels have been achieved at much lower currents. It's simple -- Less stress equals longer life. · Within the LED itself, the use of silicon instead of epoxy resin also slows the aging process, and provides a greater degree of reliability in humid operating conditions. · NX-4's new "tri-color" LED calibration further ensures display stability and uniformity over time.
It's a fact that LEDs age, and their output declines in brightness over time. But with NX-4's technical advances, Barco has not only engineered an "anti-aging" solution, but an ROI solution as well -- With the product's brightness declining to only 85% after 60,000 hours!

Brilliant colors, breathtaking grayscales
With the introduction of the NX-4, color processing advances to a new industry pinnacle -- 16-bit processing and new "tri-color" calibration on all three colors simultaneously. Each NX-4 LED can deliver up to 281 trillion colors, enabling tiles to reach staggering new levels of color depth, uniformity, and grayscale range -- a critical requirement for all low brightness applications. With a tight selection of LEDs and the 16bit processing power of the NX-4, tiles can be calibrated to a larger color triangle  one that is actually wider than the HDTV standard, delivering vibrant images with deep, uniform colors across the entire display surface. In combination with the DX-700, Barco's new 16-bit digitizer, the NX-4 delivers more colors, more detail, and a higher degree of uniformity than ever before -- without sacrificing color depth. Effectively, NX-4 and DX-700 provide a brilliant "no compromise" system that must be experienced in person to fully appreciate -- print simply does not do it justice!

Native HD -- by design
Each NX-4 tile consists of nine modules, plus a single control unit, which also houses the power supply and interface board. NX-4 tiles are 448mm wide by 504mm high (17.6 x 19.8 inches), with a 96 x 108 pixel resolution. Individually, each tile's aspect ratio is 8:9. Place two tiles side-by-side and you're spot on 16:9 -- and precisely ready for HD. Given a 20 x 10 tile array, your exact pixel resolution is 1920 x 1080 -- the native HD resolution.
