NEC introduces new laser projectors for digital signage installs

NEC introduces new laser projectors for digital signage installs

Commercial LCD display and projector solutions provider NEC Display Solutions of America has announced two new laser phosphor projectors to its professional installation lineup. The technology behind the lampless projectors gives professional installers new applications to target and potential new revenue streams, the company said.

The NEC PH1201QL projector delivers a native 4K (4096×2160) resolution, while the NEC PH1202HL model delivers full-HD 1080p as its native resolution. The three-chip DLP laser projectors each emit 12,000 lumens of brightness, and maintain 2000:1 and 10,000:1 contrast ratios, respectively.

The lampless projectors use blue laser with yellow phosphor as their light sources and are designed to emit consistent light output over their lifetimes. That means mercury-free components, no more lamp replacements and 20,000 hours of projector life at maximum brightness, according to NEC. The eco-friendly projectors are designed to be virtually maintenance free, which should translate to lower labor costs and less filter cleaning, the company said.

The PH1201HL offers NEC’s heat exchanger, a patent-pending system designed to cool the engine while creating a sealed barrier for both the optical and laser engines, thereby minimizing dust and other particles from entering the laser and optical path. The barrier helps reduce maintenance requirements while maintaining image quality and brightness, the company said.

The projectors are intended to operate in a 24×7 environment, which should open up a range of new applications in digital signage, simulation, training facilities, control rooms and high-traffic environments, giving professional installers new opportunities, NEC said.

“Laser is the future light source for the projector industry,” said Richard McPherson, senior product manager of projectors at NEC Display. “Laser phosphor projectors bring the best possible brightness uniformity and image quality over a longer period of time compared to lamp-based projectors. The laser technology eliminates the need for lamp replacement, bringing a significant cost savings over time. It’s exciting to see the new opportunities NEC’s PH Series laser projectors bring to professional installations.”

The self-contained projection system of the PH1202HL projector includes an Open Pluggable Specification option slot, the standard designed to simplify installation, use and maintenance while offering input flexibility for HD/SD-SDI and OPS accessory cards. The projector’s wide range of installation features is intended to suit any professional environment and minimize installation costs for digital signage.

NEC Display says it is the only visual technologies manufacturer delivering 4K and ultra-HD resolution products across its entire portfolio of projectors, desktop and large-screen displays.

Among the other benefits of the two laser phosphor projectors:

  • quick-start capabilities;
  • extensive input panel, including HDMI, DisplayPort and HDBaseT (PH1202HL);
  • tilt-free (360°) and portrait-mode capabilities;
  • 3D – HDMI;
  • adjustable light source;
  • Stacking Correction Tool (PH1202HL);
  • geometric correction;
  • hardware and software edge blending;
  • interchangeable bayonet lenses; and
  • power lens controls

 

Technology in Education: A Future Classroom

We’ve all come to learn how impactful technology is on the classroom. Often, when teachers are willing to make the transition, students can develop engaging and responsive habits from learning with technologies.

 

The above video expresses the imagination of its content creator, pointing to a classroom of the future. And believe it or not, this fictitious environment is really not all that far away as you may think!

A Video Wall With a Twist

A Video Wall With a Twist

Challenge

A cellular store in a Canadian mall wanted to catch the eyes of passing shoppers. The architect wanted more than a simple 5×5 video wall and designed it to fit into a corner with the last column on the adjacent surface. On top of that, the installer only had 3-4 days to get the job done.

“The challenge was the super narrow bezel, a 90 degree bend, and to maintain serviceability,” said Gil Gauthier, Certified Technology Design Specialist at Advance Pro in Winnipeg, Canada. Advance Pro is an electronic systems integrator for audio, video, communications, security and multimedia.

 

Solution

Installing

Gauthier said the biggest advantage of the ConnexSys system is the ability to hang the mount from standard strut channel, a common item for AV installers. “It’s kind of like the Lego block of the installer world,” he added.

Senior technician, Joe Premecz, expects to encounter imperfect walls on the job site, which makes lining up displays a challenge with individual mounts. The use of strut channel, though, to provide an even reference surface, allowed him to accommodate the distortions of the wall.

“By attaching the mounts to the steel, the panels were near proper alignment from the start,” he said.

The installer only had three days on site to put in the wall on top of working around the electrician, flooring and lighting installers. They were using ultra narrow NEC displays with no bezel and a total gap of 1 millimeter between displays. On top of that, the last column’s perpendicular placement would be a huge challenge.

To meet that challenge, Premecz said the ability to slide the displays horizontally and adjust the depth made it easy to line up the corner edges. They spent half a day making sure the strut channel was installed and square, then put up the 25 panels in about three hours.

“They were a huge time saver,” Premecz said.side shot

Though there was a short turn around for delivery, Chief was able to ship the new mounts directly from the factory to arrive on site when needed.

“I know the installer kind of went white when he heard the 90 degree part,” Gauthier said. “It’s already a challenge to line up. If it wasn’t for those brackets, I don’t know how he would have done it.”

The micro adjustment allowed by the ConnexSys system to line up the screens safely before locking them in place, the quick leveling using strut channel to hang the main row of four screens, and the need for ultra precise alignment for the high definition content made the job possible.

“There’s no way it would have happened otherwise,” Gauthier said. “It keeps the installer happy. It keeps the job on track. And even if the customer doesn’t care about the bracket, they care that the wall works.”

Serviceability was also key. They needed front access to adjust and change content and software. The RapidDraw release system helped the installer pop out only the displays he needed to access at the time.

 

Results

The client is running live video, sporting events, and ads to draw people in to the store. Gauthier said any specs he does, he just puts Chief in now – that whatever extra price might be involved is more than covered by savings in installation costs, allowing the company to work tighter deadlines.

“Chief listened to installers,” Gauthier said. “This is a prime example of making life easier for installation guys. They said this makes life better and easier. It makes clients happier. The overall project was easier and smoother. It’s win win win. By looking after the installers, we are looking after everybody.”
