JVC's Home Projectors Have the Highest Contrast Ratio Ever - 30,000:1

Projectors are becoming increasingly popular as the solutions of choice for home theater systems and this is the reason why an increasingly higher number of manufacturers come up with various such items, each providing certain features designed to differentiate them from the competition. And that's exactly the case with the latest projectors from JVC, namely the DLA-HD100 and DLA-RS2 models, which are the first such devices ever to boast a contrast ratio of 30,000:1.

In order to attain a native contrast ratio of 30,000:1, the projectors employ original and proprietary JVC technology in the 0.7-inch full HD D-ILA devices and optical engine used in both models. Three D-ILA devices are used, one each for red, green and blue. The projectors' new 0.7-inch 1920 x 1080 D-ILA devices reduce stray light caused by the dispersion and diffraction of reflected light. JVC decreased orientation irregularities by reducing the gaps between pixels, adopting improved liquid crystals and other innovative technologies, enabling the device itself to achieve a contrast ratio of 40,000 to 1.

Moreover, the enhanced optical engine seriously improves the precision of light polarization, helping to prevent light leakage into the projection lens and allowing for true black level reproduction. Moreover, in order to provide good quality images, the new projectors incorporate video processors from Gennum Corporation that offer high-precision scaling and Gennum's VXP technologies.

The DLA-HD100 and DLA-RS2's high performance 2x zoom lens made by Fujinon Corporation features a large-diameter, all-glass lens assembly with 16 elements in 13 groups. This lens minimizes chromatic aberration and provides a high-resolution picture by ensuring that individual pixels remain perfectly focused on the screen. For placement flexibility, the projectors feature ?80 percent vertical and ?34 percent horizontal lens shift. The projectors can easily be ceiling mounted or placed on a tabletop or shelf. To tailor the picture to suit individual preferences, the DLA-HD100 and DLA-RS2 offer manual adjustment of gamma via the remote control and an on-screen display. Moreover, they incorporate two HDMI inputs compatible with version 1.3 specifications, allowing users to take full advantage of the higher 225 MHz bandwidth, increased color depth of billions of colors and enhanced resolution and frame rates.

Both projectors also offer a V-Stretch function for the most efficient projection of extra wide screen anamorphic movies. For example, 2.35:1 ratio images from these film images are normally viewed with letterbox black bands at the top and bottom of the screen. With V-Stretch, the image is expanded vertically so that every part of the D-ILA device is utilized to create the image, increasing brightness and sharpness. A third party anamorphic lens is used to stretch the image to its full extra wide 2.35:1 image ratio, just as seen in motion picture theaters.

Both projectors will retail for around 8,000 US dollars, which are some pretty high price tags, but this is quite understandable, taking into consideration the advanced projection features these things can provide.
