JVC Visual Systems introduced two Visualization Series projectors at I/ITSEC 2017. The DLA‑VS4700 projector offers native 4K resolution with e-shift technology to display up to 8K resolution, while the DLA‑VS4010NLG is JVC’s brightest simulation projector with a new laser phosphor engine.
The VS4700 complements the VS-4500 by adding e-shifting. It features a trio of 0.69” 4096 x 2160 resolution D-ILA (LCoS) panels (3.8 micron pixel pitch) with a two-position e-shifter to enable 8K resolution, says the company. New in this platform is the ability to display 8K content at 120 fps. Brightness remains at 3000 lumens with sequential contrast of 12,000:1 (checkerboard contrast in the 150:1 range). The optical engine has also been redesigned to eliminate the spinning phosphor wheel and implement a stationary one. There are four DP1.4a connectors with support for various simulation generators in single, dual, quad stripe, or quadrant mode. This model features a 12-bit color processing engine and should ship in the March/April 2018 time frame.
JVC also has a native 8K projector (no image shifting) that was being demonstrated in the Boeing booth as part of the CRVS system. While not side by side, the image quality of the e-shifted 8K is very comparable to the native 8K projectors – at least on the images that were being shown. Certainly, test patterns will reveal artifacts. This whole topic of the definition of resolution and how to measure it remains an interesting subject.
At 6000 lumens is the DLA‑VS4010NLG projector with 4096×2400 pixels and greater than 10,000:1 contrast ratio. It features a new laser phosphor light source and is based on the SH7 model that is lamp-based. Compatible with a variety of fixed or zoom lenses, the DLA‑VS4010NLG offers 8-bit bit depth with single-link DVI and 12-bit color bit depth with dual-link DVI. Connectivity options include four DVI-D dual-link inputs, as well as Ethernet, USB, and three RS-232 ports. The DLA-VS4010NLG does not offer an e-shift capability and will be available in February 2018.
This model was being shown inside the booth using a DiamondVisionics IG running at 60 fps with a mechanical shutter for smear reduction. – CC
