Specs: 100K:1 CR, 116% NTSC, 128 individually modulated clusters (on 42" panel), 1151 RGB LEDs.

RGB LEDs, eh? Very interesting. I know that I speak for quite a few others when I say that I've been waiting to see the introduction of RGB LEDs for backlighting. The reduction in power consumption is also promising.

Unfortunately the LED BL in this incarnation will not live up to its promise. If your read the original message:

JVC employed its proprietary "area control LCD driver" technology to raise the contrast ratio. Locating LEDs right under the LCD panel, the driver controls the luminance of the panel surface in 128 areas. Specifically, the driver controls the luminance of the backlight system for each of the 128 areas in the LCD panel after analyzing the luminance distribution of the video input signal.

This means that inevitably there will be visible artefacts in dark scenes, as 128 areas are not enough . Recent Samsung LED BL LCDs (81 series) which are in shops suffer from this problem.

"Regarding the control areas, JVC said that the area control effects lower if the number of compartment areas is under 128 and the technology costs too much to incorporate if the number rises above 128."

According to JVC, 128 is the magic number in size 42".

It's a start, though. And IIRC, the Samsung 81f sets use *all-white* LEDs for their backlighting, not *RGB.* So your comment may or may not hold entirely true in this case. Real-world performance will give us an answer.
