HiddenWires: Establishing a new benchmark in flat panel TV design, JVC on Wednesday unveiled the world’s thinnest LCD TVs with built-in tuners. 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 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 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 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.

Interesting article. The question is, what size is the screen?
