plasma or lcd tv?

I just recently bought a Samsung LED, which is sweet. It has a 6 star energy rating, and thinness can be a bonus if you want to hang it on the wall. This telly is only 30mm thick :o
Plasmas are cheaper, but in the end, it was the big difference in energy consumption that swayed me.
Blanka:
The biggest reason LED uses less energy is that those screens are LESS bright!
Many CCFL screens can do 400-500cd/m2 with ease, where 200cd/m2 is the new standard for LED.
If you dim an CCFL monitor, energy consumption goes down as well.
So it is a little bit comparing Apples with Pears.

Maybe. But it seems to me that LED backlighting is using energy much more efficiently. I actually heard some people are complaining that the LED tvs are too bright! You can dim LED tvs as well, which gets you back to LED using a lot less than plasma.
Blanka:
CCFL is still more efficient than LED, but LED has an advantage that it emits in one direction. That can be handy for edge-light systems, of if displays have a certain depth, for direct backlight.

HD projector with a 100 inch screen FTW!
