I went to see a friend of mine just two weeks ago. He had bought a brand new 32-inch Philips high-end flat-screen TV. The TV had a property of backlighting (or should I say rear lighting for not to make confusion with the inside panel lighting which allows the display's picture to be seen) at the backside of the telly - halogen or bright LED-lights on both sides of the rear casing - which illuminated the white living-room wall behind the TV. The idea of the lights were, that their color and brightness changed in real time depending on the picture shown at the TV display according to it's brightness and colors. I learned and heard of this the first time. It seemed really good thing and the television was much more comfortable to look at at dimmed or dark room. And it enabled with a whole new way making the most out of changing contrast and brightness scenes of dark and shadowy and bright and light, as the pupils of the eyes were much more than ordinary helped to adapt watching the display's image with the changing rear lights projected to the white wall right behing the TV. What is this feature called? what's the right term? As you can't find any information about it when you try to search for it with words like "LCD rear(or)back lighting", as you only end up with a world of results concerning the lights inside the panel which enables the display's picture to be seen. I fear not this isn't a feature patented by Philips and solely available for use on it's own panels? Those of you who might know more on this than me, could you tell me how rare feature these changing behind projecting lights are on LCD's and other flat-screens, as this is the first time ever I have heard of such a thing? How much more does it add to a cost of the display? I posted more than a couple of days ago pretty much the same post for the Finnish boards of Afterdawn, and I have not got a single reply since so far, as I feel nobody really knows much about this, at all. I wanted ask the same on the international board and see, if a few people here might know a little more about it. I think this is very interesting, great and promising feature. And I wonder, how I have managed not to heard more of it before.
By simply surfing the Philips web site I'm sure you could have found the name of the technology yourself. Anyway, Its called Ambient Light technology and yes it is patented by Philips for use in its plasmas only. I find that most people don't have large white walls. So they end up turnning the lights off which makes them more of a gimmic than a technological break through. Other manufactures simply put light sensors in there high end tvs so that the contast and brightness can be automatically changed by the tv set when the lighting conditions change. But if you like the ambient light stuff more power to ya. Ced
-Yeah, I really did like. I think it was great. Have you seen it yourself before taking on a clear opinion? And it doesn't require by no means specially a "large" white wall, neither is it only used in Philips' plasmas but as well in LCD's. Ordinary blond colored livingroom wall with a a feet or perhaps even a two of free surface behind the screen from the side and top borders of the TV do perfectly. But nevertheless thanks for the informing reply. It's really shame that this feature it's solely reserved for Philips.
