Black is a lack of any and all colors you fucking idiot.

I'll let you figure the rest out yourself.
Idiot.

But the florescent backlight is always on...it can't choose which pixels to illuminate.

Sorry I forgot to call you a fucking downy who didn't make it past grade 3.

which is why you'll never have true blacks on a the worthless piece of shit that is LCD
plasmas on the other had could literally turn off individual pixels and back on nearly instantaneously
humanity lost something great when big corp decided they'd no longer give us good tech.

too busy fucking us to care i suppose.

Don't OLEDs produce blacks just as good as Plasmas?
