Why are WLEDs so popular?

I know they don't consume a lot of power and that they're environmentally friendly, but their color gamut is so low. NTSC color gamut shouldn't be less than 95%. Twould be nice if my Apple 24" had a higher color gamut and 120 Hz input.

Will LCDs die out before RGB LEDs can take off, or will at least 1/3 of next years models RGB LEDs? What percentage of next years LCD do you guestimate will be RGB LED? Also, will any of them offer 120 Hz input (I thought that HDMI 1.4 had enough bandwidth for 1080p @ 120 Hz)?

It would be nice to have a glossy (yes I know that the extra vibrance is at the expense of accuracy) H/Alpha IPS with minimal processing (no overdrive), 120 Hz input, low power consumption w/ all high quality circuitry, and an RGB LED. A 24 or even 27 inch couldn't be more than $1.2K, could it? I would get a glossy OLED, but they don't have 120 Hz input.

because marketing is effective. so many times people will talk about led as if it were a separate tech from lcd. rgb led seems to have died for the time being, sony stopped making them, i heard they have issues with color drift, which makes sense if each color led fades at a different rate, that has to be a pickle of a problem to deal with.

because people like thin. Apparently they stand there all day looking at the profile of the tv.

Yah, it all comes down to LED backlit displays being thinner. Forget about colour gamut of "white" LEDs, CCFL backlights don't have a great gamut either. The big problem is that the uniformity on edge-backlit LEDs is just awful. No one cares. It's thinner, and its HD. That's all that the matters.

I also thought it was because of marketing.

On the plus side, my LED Cinema display isn't edge lit like those shitty new tvs are proud of being.

There are actually different kinds of WLEDs. However, if they provide more color gamut, then they don't provide luminance as power-efficiently (320 cd/m brightness is plenty though). That said, I think it would be best if they used WLEDs that had the largest color gamut and to just keep the brightness under 320 cd/m so power consumption doesn't get excessive. I'm sure my LED Cinema uses either the balanced WLED or the most luminance efficient one which would explain the high brightness, low power consumption, and pisspoor color gamut.

WG-CCFL's can cover 92% or even 97% of the NTSC color gamut, which is sufficient. Less than about 82% isn't though.
