At CES, JVC showed off its super slim LCDs, but at the time there wasn't a lot of detail on them. Today, the 42" LT-42SL89 and 46" LT-46L89 are shipping, priced at US$1,900 and US$2,400. Though the 38mm thick TVs actually measure 74mm in the middle, they come with an integrated HDTV tuner, which other slim TVs barf out into an external box to achieve their sub-inch status. I also admire the engineering involved in building a backlight that uses diffusion panels to kill the spots from placing lights too close to the panel, without killing the light.
JVC SUPER SLIM LCD TV FEATURES SLEEK, THIN-BEZEL DESIGN AND REDUCED POWER CONSUMPTION
Technology available in two screen sizes
DENVER, Sept. 4, 2008 - Establishing a new benchmark in flat panel TV design, JVC now offers a pair of super-slim LCD TVs, both with a built-in TV tuner. The new line of super-slim Full HD TVs also weigh less and consume less power than conventional LCD TVs.
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 centre. The design ensures that from nearly any angle, the sets present a super-slim appearance. Complementing the slim design is a thinner bezel, further minimizing the presence of the cabinet.
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 (see diagram 1).
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 (see diagram 2). 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 (see diagrams 3 and 4).
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.
