Message Text: JVC now offers a pair of super-slim LCD TVs, both with a built-in TV tuner as well a small 4K2K ultra high definition projector, the DLA-SH4K.

JVC's new slim LCD TVs, part of the company's Procision series, feature a cabinet that across most of its width measures a mere 1.5 inches (39mm) deep, with a maximum depth of just 2.9-inches (74mm) at the panel's center.

The new super-slim design will be available in two screen sizes in the U.S., the 42-inch LT-42SL89 and the 46-inch LT-46SL89. Both offer 1920 x 1080p resolution.

The slim design was made possible through the use of a new JVC-developed slim panel backlight unit and power supply substrate, or chassis. The new slim LCD panel backlight unit is 40 percent smaller in depth and bezel width compared to a conventional LCD backlight, measuring just 0.79 inches (20mm) deep and 0.51 inches (13mm) wide. In addition, the unit weighs only 26.4 lbs (12kg) and consumes a mere 145W.

Efforts to reduce the depth of an LCD panel backlight result in uneven hot spots appearing on the LCD screen surfaces because CCFL light sources are brought closer to the liquid crystal panel. To overcome this problem, either light-diffusing plates are applied or more CCFL tubes are used. But the former approach can result in lower brightness, while the latter approach can be costly and increases power consumption.

JVC's display engineering team succeeded in developing a new, slimmer backlight unit by optimizing the light-diffusing plates and light-reflection sheets, as well as improving its overall composition. This provided uniform light-diffusion at all the corners and edges without the addition of more CCFL tubes, while maintaining adequate luminance to ensure that the screen always remains bright.

JVC also developed a slimmer yet efficient power-supply substrate and employed a direct-mount configuration for it on the LCD panel backlight unit with a fan-less heat dissipation system to further reduce power consumption.

Both models will be VESA compliant for easy wall mounting, but JVC will also offer its own mounting solution - a wall mount designed to position the slim TV closer to the wall than does a standard mount.

Both sets include a full complement of connections, including three HDMI inputs, two component inputs, one S-Video in and a PC input. Other features include front touch sensor controls, a headphone jack, USB picture viewer and an illuminated universal remote control.

The new JVC super-slim LT-42SL89 and LT-46SL89 are available now at approximate retail prices of $1,899.99 and $2,399.99, respectively.

4K2K ultra high definition projector

Based on the company's new proprietary 1.27-inch 10 megapixel D-ILA devices, the DLA-SH4K projects images at greater than 4 times the resolution and clarity of the industry's latest full high definition projectors.

The DLA-SH4K will be on display throughout the CEDIA show in the JVC Theater located at The Denver Center for the Performing Arts next to the Denver convention center.

The projector's chassis achieves a remarkable 65% reduction in size compared with conventional projectors in its class. This was achieved in part by using JVC's latest 1.27-inch Direct Drive Image Light Amplifier (D-ILA) devices and a new optical system. D-ILA is a proprietary form of Liquid Crystal on Silicone (LCOS), a reflective technology that offers far greater pixel density than competing devices.

The D-ILA devices used in the DLA-SH4K provide a native 4096 x 2400 resolution-multi-screen display modes that allow users to view up to four Full HD screens at a time. A new optical design featuring an 825 Watt Xenon lamp generates a light output of 3500 ANSI Lumens and features adjustable lamp power that ranges from 825 to 660 watts.

Two DLA-SH4Ks can be stacked for increased light output. In addition, the projector can be inclined up to a 90-degree tilt angle and has a horizontal lens shift of 25% and vertical shift of 50%, which enables flexible installation.

The DLA-SH4K includes DVI-D (dual-link) x 4 input terminals that accept a wide variety of input resolutions. In addition to the RS-232C and USB connections, an Ethernet interface makes adjustment and installation from web browsers on PCs possible. Furthermore, networking allows multiple projectors to be operated with a single PC and an email function also enables the sending out of error messages and lamp replacement reminders.

JVC will offer two lenses for the projector, the GL-MS4015SZG 1.22x zoom lens for screens up to 300 inches, and the GL-MS4011SG short throw lens for screens up to 250 inches. The DLA-SH4K is available immediately.
