Does that make my ks9000 and sony w900a QLED TVs as well?
No, those displays use quantum dot material on the light guides to turn a blue backlight into pure white light.
This white backlight then goes through regular color filters that block light to create red/green/blue subpixels.
So the red subpixels block green/blue light, green blocks red/blue, and blue blocks red/green.
QLED uses a blue backlight and replaces the color filters with individual sections of quantum dot material.
So the red subpixels transform the blue backlight into red light.
Green subpixels transform the blue backlight into green light.
Blue subpixels transform the blue backlight into the specific blue light they want.
This means that the subpixels are now made of emissive material, which is why the viewing angle is even better than LG's WOLED.
Since quantum dots
transform the blue backlight directly into RGB colors, rather than
filtering white light to create red/green/blue, it's a much more effective and efficient process - which is why the color volume is so big, and why they are now able to reach 2000 nits brightness.
I don't like Samsung's marketing department calling this "QLED" because it should really be "QDCF", but Samsung did the exact same thing with their LED-backlit LCDs and most people just call them "LED TVs" now.
I'm sure that it's done intentionally to make people think they're using similar technology to OLED.
Hopefully other companies will be able to do the same thing.
If LG are able to switch from a WOLED design to using a blue OLED backlight with quantum dot color filters it would greatly improve color reproduction on them and hopefully also increase efficiency/light output enough to drop the white subpixel altogether. Or they could at least use quantum dots to create a D65 white instead of that cyan-tinted white they have now which puts an ugly color cast on the the image.
CLED is impossible to mass produce so it'll never happen.
Isn't it one LED per pixel or something crazy?
Sony shouldn't have ever shown that to the public tbh.
Isn't there talk of Apple switching to µLED displays in some of their products soon?
It's expensive right now, but Sony are producing CLEDIS displays commercially for video walls.
