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
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
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

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
