Stewart Filmscreen and Display Development recently hosted a special dealer and press event demonstrating new and unique two-piece projection solutions, the results of their respective engineering efforts over the last several months.
The event included a demonstration of the new Display Development IW-4 (dual lamp, triple DLP chip) “In-Wall” projector projecting onto the 14-foot wide Stewart Directors’ Choice masking system with acoustically perforated StudioTek 130 (1.3 gain) screen material. The projection system – through it’s proprietary ventilation system that monitors key temperature points inside the projector chassis – is designed to be built-into a wall only 8.5-inch in depth, featuring its own surface-plated mirror system for projecting the image forward.
The included mirror system has significant offset adjustment and geometric distortion correction for maximum application flexibility. Display Development also offers the 6,000 Lumen output IW-4 projector (an 8,000 lumen step-up to the IW-3) that has more than enough output to offset the small amount of light loss for installations where acoustically perforated screen material is needed or preferred.
Also at the event, a Stewart Luxus GreyMatte 70 Screenwall received its image from the Display Development HD 3. The HD 3’s dual-lamp, triple-chip 8,000 Lumen projection system was shown as simulating an installation solution where obstacles such as a chandelier or support-beam might be in the middle of the normal light path. The projector was positioned to the right, approximately 30 degrees off center. Because of the extreme offset capabilities of the HD-3’s light path, lenses and built-in warp engine, the picture was displayed artifact-free and squarely on the screen, according to the company.
Display Development is also the exclusive provider in the U.S. and Canada of avielo brand projectors manufactured in Norway by projectiondesign. Attendees enjoyed the unique capabilities of the SuperWide235 projector together with the fully opened 14 feet wide 2:35:1 CineCurve StudioTek 130 screen system. The avielo SuperWide235 features the native 2:35 to 1 (2560 x 1080) DLP chip that projectiondesign co-developed with Texas Instruments. The additional cost and questions about shortened focal length are eliminated by not having to have an anamorphic lens system added. Jim Burns, president of Display Development, observed “By not using anamorphic lenses, we also don’t have the 20-50 percent in contrast ratio loss created by the reflection of light between the lenses in an anamorphic lens system.”
Lastly, additional rear projection applications were shown with the Stewart StarGlas 60, utilizing the ultra-small, high precision avielo quantum projector. The demonstration confirmed that with the use StarGlas and the avielo SuperWide235 and its available 0.8 to 1 short throw lens, the application performs without blooming or other artifacts.
“We’re very excited about the ability of doing a 2:35 StarGlas using the SuperWide235 with the short throw lens," said Joaquin Rivera, Stewart Filmscreen’s vice president of sales. "Because we don’t have to use an anamorphic lens system we can now cut the needed space to implement the system by more than one-half. Because of the innovation of both Stewart Filmscreen and Display Development, we truly have totally new combinations that make two-piece projection systems a possibility in more places than ever before. We can now make a customer’s entertainment dreams come true – anywhere inside or outside their home.”
