Philips 42PFL9803: Best LCD contrast ever?

The world has gone LED crazy -- you can't throw a light bulb without hitting something lit by LEDs these days. Your TV is no exception, with companies such as Samsung and Sony offering models with an LED backlight. Philips wants in on the diode action, so its Cineos PFL9803 Ambilight range features an LCD panel backlit by white LEDs, rather than the traditional cold cathode florescent lamps.

FTA: "The backlight in the 42-inch 42PFL9803 is provided by 1,152 individual LEDs, which are arranged into eight rows. Each row is, in turn, made up of 16 LED 'segments' and each segment has nine LEDs. Philips claims this means you'll see a contrast ratio of around 2,000,000:1, which is better than pretty much anything else on the market. We remain sceptical, as always, when it comes to manufacturers' quoted figures."

This is the first time I've seen a manufacturer talk about the construction of the backlight and some of the flaws... White object on a black background... gives a glow ring around look (guess the light spill around the edges show through) and mention of unusual effects at screen credits etc. I note this is with white LED's and not the tri-leds others use, which in my mind is only a half step.
