Myself, I think the kind of "ink" that will go in to the Kateeva will be "QD ink" and not "OLED Ink".


Of course , time will tell, but how long have we been hearing about OLED TV's via Kateeva?


I bet we see QD TV's via Kateeva well before we see Kateeva Oleds, particularly since the same individual cofounded both a Quantum Dot Company as well as the Kateeva.

Well. The guy is one of the founders. Currently he is a Kateeva advisor. Steven van Slyke, the co-inventor of OLED, on the other hand, is Chief Technology Officer of Kateeva..

Printed OLED is the focus of Kateeva. Show me a link which shows that Kateeva is also focussing on printed Quantum Dots.

So far this is what I've found, but I can't fine the "whole Article" yet


"www.displayalliance.com/news/tag/avionic


1st

"May 3, 2015 - What the hell are quantum dots, and why do you want them in your next TV? ... It is the first product to emerge from Kateeva's YIELDjet platform, a breakthrough ..."


2nd


"The DuPont and Kateeva cooperation is non-exclusive and manufacturers will not be restricted in their choice of equipment or materials through this effort; it will only aim to increase viable, manufacturing-ready options. The companies expect to provide cross-referenced data for DuPont materials with Kateeva printing equipment."


Samsung bought a Kateeva, last year, (or so the rumours go), I can post links to that if you need it, but just google
Samsung kateeva.


Add to this The report that Samsung "may ditch" Oled in favor of QLED, and if I were a betting man, my bet would be on the QLED.


I suspects we will see a lot more in the next few days.

I don't.

Invested in... yes. That's all, and it wasn't a rumor.

There has never been a demonstration of a workable quantum-dot emissive TV. Not sure how you've concluded a company pursuing OLEDs is suddenly switching to a technology that basically exists only in theory.

There is no difference in HDMI cables. If you can see the picture without visible dropouts or sparklies, the cable is working at 100%. No other cable will display a better version of that picture. You're simply wrong if you think there is a better digital cable than one that is already working. (Oh, and plasma didn't die because of logistics problems, nor does OLED ship in big boxes because it comes from Korea.)

Not a chance. Where did you get this idea from?

Yeah, at one point a few years ago I searched high and wide for even evidence of a lab demo of non-light activated QD emission and never found one. The theory was that you could activate the things by electrons directly and have them excite.

I do understand the reasoning, and I believe it's hardly a crazy idea:

1. QD's absorb and retransmit light at varying frequencies
2. Light is part of the Electro-Magnetic spectrum
3. All things that are part of the EMS can interact directly with anything electro-magnetic in nature, including electrons.

Electrons themselves can also be represented with duality: a wave and a particle. So I'm not completely sure what the hold-up is on this, but it must be significant because there's nothing there.

I would love it if someone actually found a demo of such things, but be warned, googling for it is a nightmare because nearly every link will discuss photon activated QD.

Eh. Thai food is nothing but totally lame Chinese food. I'll pass.

In OLEDs the gamma rays that get down-converted into visible light can never "escape" from the emitter (in fact OLEDs lose their brightness when they start to produce less gamma rays).

QDs as in TVs would use a lot of toxic material (not that OLEDs don't use toxic materials, but OLEDs are only moderately toxic when they burn due to "oils" (or in other words, solvents which are used to liquify OLED material (which comes in power form) in order to vaporize it) that tend to become radioactive over time and emit gamma/X rays...

So instead of glowing black levels it'll be us that are glowing. That's a comforting thought. lol
