*Native contrast of 15,000:1 for home theatre projector class (JVC survey as of 14 November 2006).

The secret behind the 15,000:1 native contrast ratio* is a newly-developed 0.7-inch full HD D-ILA device combined with a new optical engine.

Newly developed 0.7-inch full HD D-ILA device

Conventional D-ILA devices suffer from surface unevenness, minute gaps and irregularities that are unavoidable using normal semiconductor manufacturing processes. Discontinuities between individual pixel cells or where the pixel cells are connected with the underlying semiconductor structure disturb the orientation of the liquid crystals, and the resulting diffraction and other effects lead to stray light. In the manufacture of this newly developed device, technology has been adopted to ensure extreme planarization; this reduces to an absolute minimum such stray light. Moreover, as a result of employing new liquid crystal materials and orientation technologies, the gap between pixel cells has been optimized, reducing it from the previous 3.2 microns to 2.3 microns, cutting light loss from the liquid crystal layer itself, and significantly improving the compensation accuracy. Such new technologies have realized the extremely high device contrast ratio of 20,000:1, and at the same time halved response time from 8msec (Tr+Td) to 4msec.

Use of three new 0.7-inch full HD D-ILA devices results in a flicker-free high-definition picture

JVC’s original D-ILA (Direct-drive Image Light Amplifier) technology ensures a natural, rich, flicker-free picture which does not suffer from the sort of color-breaking phenomenon that can often occur with single-device projectors, especially when there is rapid movement. The result is a smooth picture, like that produced by film, with fine detail from one edge of the screen to the other.

Film-like picture with inconspicuous pixels

There is no obvious “screen-door” effect (a faintly visible mesh representing pixel cell boundaries) when using D-ILA devices, so the high-definition picture is like that produced by a film projector.

Professional-standard grayscale performance

JVC's original D-ILA pulse drive produces clear, high-precision gradations without employing error diffusion. While delivering a 15000:1 contrast ratios, high-precision calibration technology enables the faithful reproduction of dark pictures, in which luminance is 10% or less, so that the blacks can still be differentiated, thus resulting in pictures with appreciable texture.

Excellent color reproduction

Thanks to an optical engine developed by JVC, colors are reproduced with smooth gradations and minimal noise. The resulting color reproduction is ideal for movies. Since vertically oriented liquid crystals are used for the D-ILA device, it is possible to reproduce objects that are normally black with true blacks. And, irrespective of brightness, consistent response is assured, allowing the reproduction of a wide range of intermediate colors.

New optical engine with wire-grid polarizers

Using a conventional PBS (Polarizing Beam Splitter), comprised of a glass prism on which has been deposited a multilayer interference film, optical properties can vary considerably depending on the angle of the incident light beam; this makes it difficult to realize high contrast.
However, the wire grid design employed for JVC's newly developed optical engine uses an inorganic reflective polarizing plate made from a glass substrate on the surface of which are aluminum ribs with a width of a 20~30 nanometers, aligned with a pitch of 120~130 nanometers. This has very little angle-dependence and it succeeds in reducing to an absolute minimum the amount of stray light reaching the lens during dark scenes. The combination of this polarizer with the newly developed D-ILA device increases contrast by a factor of 5.

Image processing circuit with video processor made by Gennum Corporation

The projection system features the GF9351, a video processor made by Gennum Corporation. This video processor ensures the faithful reproduction of high-quality images thanks to a high-precision scaling function and four VXP™ technologies as the followings.

2x zoom lens plus front fan intake/exhaust design for flexible set-up

Lens system

The projection lens features a large diameter, all-glass lens with 16 elements in 13 groups that significantly reduces chromatic aberration and ensures a high-resolution picture, with every point on the screen perfectly in focus. Also, the high-performance 2x zoom lens enables you to enjoy a large and impressive image even in smaller rooms that do not permit typical recommended throw distances to the screen.

Lens shift function: +/-80% vertical, +/-34% horizontal

The intelligent projection system features a +/-80% vertical and +/-34% horizontal lens shift function, allowing you to set up the system more freely.

Front fan air intake/exhaust design for the cooling system

Both the air intake and exhaust are located on the front of the projector to maximize flexibility for projector installation. The simple, clean design means that there are only interface connections on the back panel, giving you more freedom of choice in deciding where to put the projector. For example, the DLA-RS1 can be placed next to a wall if ceiling mounting is not possible. And, regardless of whether the projector is ceiling mounted or on a tabletop, the lamp is easy to replace from the side panel.

User friendliness as well as top performance

Convenient, detailed video adjustment menu

The projection system features a convenient video adjustment menu that allows you to easily adjust the picture to suit the source video and your own preferences.

Self-illuminating remote control

The buttons of the remote control light up automatically, making it easy to operate even in a dark room. The remote control includes direct keys to adjust frequently used functions such as contrast and brightness, in addition to video input selection.
