0.7" Full HD (16:9) D-ILA device x3
The device for the DLA-HD750/HD350 is designed to significantly reduce stray light caused by phenomena such as the dispersion and diffraction of reflected light. Improvements by JVC on planarization technology — making the surface more even and reducing the gaps between pixels — have enabled a device-only contrast ratio of 40,000 to 1.
Three D-ILA devices for a smooth, film-like picture
JVC D-ILA technology employs three (RGB) devices for a naturally rich, flicker-free picture without the kind of colour degradation that can often occur with single-device projectors, especially when there is rapid movement in the image. The result is a smoother picture, like that of 35mm film, with fine details all the way to each edge of the screen.
Optical engine with wire-grid polarisers
JVC's optical engine with wire-grid polarizers dramatically improves the precision of light polarization, helping to prevent light leakage into the projection lens and allowing for true black level reproduction. With a conventional PBS (Polarizing Beam Splitter) — comprised of a glass prism with multilayer interference film — optical properties can vary considerably depending on the angle of the incident light beam, making it difficult to realise high contrast. However, the wire-grid design employed by the JVC optical engine uses an inorganic reflective polarizing plate made from a glass substrate on the surface that has ultra-fine aluminium ribs. This unique design keeps the amount of stray light reaching the lens down to an absolute minimum. The combination of this polarizer with the newly developed 0.7-inch full HD D-ILA device enabled the DLA-HD750 to realise a 50,000:1* native contrast ratio.
The optical engine also ensures that all colours are vividly reproduced with smooth gradations and minimal noise to heighten viewing enjoyment especially when watching movies. Furthermore, because vertically oriented liquid crystals are used for the D-ILA device, it is possible to increase the level of normal black images to true black. And, irrespective of brightness levels, consistent response is assured to allow for the reproduction of a wide range of intermediate colours.

Advanced HQV Reon-VX video processor
Both projectors incorporate the HQV Reon-VX video processor developed by Silicon Optix. To ensure excellent image reproduction, this processor features precision I/P conversion and scaling with full 10-bit 4:4:4 signal processing as well as an HQV noise reduction function to block mosquito noise.
High-performance 2x motorised zoom lens
The newly developed high-performance 2x zoom lens with motorised focus features a large diameter, all-glass lens system with 17 elements in 15 groups that includes 2 ED lenses to project a full HD image with exceptional depth. And to display the deepest black possible, this new high-precision lens is also equipped with a 16-step* lens aperture that allows adjustment of brightness according to user preferences and usage environment. What's more, the high-precision lens also reduces chromatic aberration and colour bleeding significantly.

Flexible and easy set-up
Setting up is easier than ever before as the ±80% vertical and ±34% horizontal lens shift function is now electrically operated, allowing the projected picture to be moved horizontally or vertically effortlessly via the remote controller. What's more, the 2x motorised zoom lens — with throw distances of 3.0 metres to 6.1 metres for the 100-inch display — makes tedious zoom or focus adjustment easy thanks to its high-performance motor.
And when positioning the projector outside of the lens shift coverage area, the Digital Keystone function with ±30° vertical and ±40° horizontal adjustment helps to make distorted images look more natural.
Also featured is a unique automatic lens cover that opens and closes with power on/off to protect against dust, so even if the projector is installed up on the ceiling, you're assured of easy, trouble-free operation via the remote controller.
