Have they fixed the light bleeding issues? Probably not.

Why does OLED need backlighting?  In OLED technology the pixels themselves are the light emitting devices, and it's my limited understanding that it does NOT require backlighting since the pixels ARE the light source.  It's this feature that makes OLED so attractive in mobile devices since you eliminate the need for a battery sapping backlight that's constantly "on."  I've never understood OLED for large devices since the pixel life span is sort of poor and you're really not trying to conserve energy.  I really don't understand OLED needing a backlight.  Can someone rip one of these TVs apart and explain this hybrid technology for those of us that think OLED supplants backlighting requirements?

Where does this compare with Plasma TV's. I still feel those are best on the market, in terms of color, and its 600hz refresh rate. LED's TV are nice because they are slim and light but watching stuff in 3D and movies in general on both screens, i personally feel Plasma is the best. LED is such a buzz word and like the previous poster said its just backlighting.

 

Am I wrong on the Plasma TV? I plan on getting a Panasonic one soon. They are half the price of those LED TV's and blow them away in my opinion. Sucks Plasma is not getting the love, because LED is the buzz word, that Panasonic was cutting back on TV production because it was losing out to the LED TV market.

The high end LED TV's today definitely compete with Plasma display's in terms of picture quality. The LED backlight is actually a very important feature in the case of LED array display's (edge lit LED TV's don't offer a significant improvement in picture quality over conventional LCD's). An LED array when combined with advanced control hardware can control the backlighting for specific pixels on the screen which can produce drastically better color reproduction and contrast.

No LCD (including LED LCD's) can compete with Plasma in terms of refresh rate (some specs may claim that an LCD has a 600Hz refresh rate or whatever, but just because the screen is refreshed 600 times a second doesn't mean that the pixels can actually switch colors that quickly). The only aspect where LCD refresh rate will actually be an issue though is when watching 3D. Otherwise refresh rate is probably the least of your worries.

But Plasma does have it's downfalls as well. Plasma is seriously effected by burn-in. In cheaper models this can be a huge issue. My brother has a Plasma and I hooked up my laptop to it a few times to watch a movie, and even after a couple minutes, my desktop would be visibly burnt onto the screen for 10 seconds or more. His roommate left his DVD player menu on overnight once, and it took months to completely disapear. Letterboxed content can also cause issues.

Plasma also uses a lot more energy then LCD, are heavier, thicker, and hotter.

There's still no 'perfect' display technology. Even futuristic OLED has it's inherent drawbacks. You simply have to look at the pro's an con's of each technology and make a decision yourself.

i know most of the draw backs for Plasma. But thats why I wont go cheap on it. Panasonic is the best out there for Plasma, as i dont think there are to many others. In terms of the 3D to me there was a huge difference with picture quality between Plasma and LED TV. I still noticed the motion blurs to the edges on LED and nothing on Plasma.

You are right there is no perfect solution because then the makers wont make money. Or we would have the perfect TV and smartphone. I still think i rather have a Plasma then LED TV.

There is still not an actual LED TV.  Its false advertising to the max.  The LEDs are used for backlighting, not actual pixels.......

The average consumer has no idea what LCD, LED, or OLED stands for, never mind what they actually mean. LED is just a short form market term to make it easier for consumers to differentiate between LED-LCD TV's and conventional LCD TV's, which actually have a significant difference in technology and are 'capable' of significantly better display quality. And there absolutely is an array of LED's in LED TV's. That's hardly false advertising.
