How low can black tv levels get

[theflyingwasp]

With this years panasonic zt60 v kuro and now oled tvs coming out how low can black levels get .how far was the kuro from absolute black if there is such a thing.one of the calibrators from this years value electronics show said that they were super nit picking with this years top plasmas,all were amazing tvs the technology isnt moving forward that much apart from all the smart function rubbish like touch pens and voice recognition.

OLEDs can produce the deepest blacks (some plasmas will run close) by simply switching off all light in the pixel. What's equally important, is to produce details within the blacks, like silhouettes & shadows.

Current LED sets are known to have trick a whereby the led lamps would be turned off entirely for a brieft moment, it is quite a neat trick - then absolute black! Infinite Black as there is no light in the panel. Some critics say that is cheating do not count in the evaluation of black levels.

But I have to say, it works.

Compare 0.05 cdm/2 as how dark a LED screen(philips,sony,samsung etc) can be but with the lamps still switched on and Plasma can go down to 0.0002 cd/m2. Yes, it is a plasm feat that the blacks can merge with the blacks in an entirely dark room. Not a feat LEDs can match but Plasma guys get a real kick out of it and can be awesome.

But the caveat is that not everyone sees the Tele in a dark dark room.Most people will dim the overhead lights. So an LED TV's blacks can be 'blacker' in an artificial lit dim room hopefully with no reflections on the screen. In that respect, I do not think plasmas have that clear advantage in that viewing context.

Philip's eyemoth screen filter is suppose to take care of any ambient reflections on screen so that set is probably the best for bright room light viewing with as deep black as you could want in theory. I like the led lamp switching trick as it makes the screen go 100% black in scenics. First time I saw it I similed admirably.

Surely only as black as the screen itself when it's switched off?

LED TVs can only display absolute black with no other content on screen. (Even then it's not technically absolute black). Introduce a single flashing pixel and the TV reverts to the same poor black level displayed with any content on screen. In other words, if you plan on watching anything other than a completely black screen, the turning the panel off "trick" is just as it sounds, namely sleight-of-hand.

It's a shame manufacturers abandoned local dimming backlighting in favour of slimmer screens.
