Sounds about as useful as their Ambilight technology. I guess we'll see though.]]>Dec 19th 2005 1:02AMhttp://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/http://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/

No thanks, Philips.]]>Dec 19th 2005 1:02AMhttp://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/http://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/Dec 19th 2005 1:02AMhttp://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/http://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/Dec 19th 2005 1:02AMhttp://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/http://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/Dec 19th 2005 1:02AMhttp://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/http://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/Dec 19th 2005 1:02AMhttp://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/http://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/
Assuming LEDs wouldn't require more power to switch on and off continuously, then there's still "The backlight has to be three times brighter than usual to compensate for being shut off in cycle (up to 60 times per second, presumably)".
If the backlight on/backlight off ratio in one cycle exceeds 1/2 (or backlight on represents more than 1/3rd of a cycle), then it should consume more power than usual i guess.

It would all depends on how long a complete screen refresh lasts in a cycle.

Philips is really going in some weird directions with their TV's lately. I saw that Ambilight thing in a store this weekend and I just can't even imagine living with that; it's not even a gimmick that looks good in a store, which doesn't bode well for how it would do in a home. This flickering LCD light seems like a real step backwards - "hey, let's give our high-end LCD's all the problems inherent with LCD technology, *and* the worst of CRT technology too - flicker!"

I mean, CRT's do still have a nice picture, but they've got issues too. I don't much see the point in incorporating CRT's *problems* into new technologies just to make them more "CRT-like". Next thing you know Philips will be purposely screwing up the geometry and simulating misaligned convergence on their LCD's just to further this goal. "No more will you have to deal with perfectly straight lines and distractingly high sharpness and resolution!"

I really doubt they could pull it off using CCFLs, as they do take significant amounts of power to turn on, and usually have some startup delay (initial surge is required to start the gas glowing.)

If they managed to get the timing down absolutely perfect, you shouldn't notice the flicker as it would be blocked by the pixels during change, but I seriously doubt it will be an easy thing to sync lights with LCD pixels at 60hz+.]]>Dec 19th 2005 1:02AMhttp://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/http://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/
Well, assuming that the backlight in the new Philips LCDs is LED (versus CCFL), a related techique may help with black level. I've already seen reports of upcoming LCD displays where the backlight brightness is modulated based on (average?) scene brightness. This has the effect of dramatically increasing subjective contrast range, though with deleterious effect on gray scale.

Sony's VPL-HS51 3 panel LCD front projector has employed the technique to great success, albeit with an iris rather than direct modulation of the light source.]]>Dec 19th 2005 1:02AMhttp://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/http://www.engadget.com/2005/07/18/philips-makes-lcd-tvs-all-crt-like/ I'm not even gonna comment on what technology they are going to use for the light but I do have this to say : if it's LED I expect that the 'white' won't be a very good white.
I don't like the 'white' that current 'white' LEDS make. It seems very cold and lacking in warmth to me. Maybe they should try tacking TWO lcd's in front of each other to increase the black level instead.
