No they deposit the OLED as an un-patterned layout. It's all stacked, one layer atop the other.

The pixels are made solely via the transistors on the backplane and the way the color filters are cut.

This was a nod to the impossibility of large masks using any known materials.

With Samsung's market share in the premium segment rapidly deteriorating, is it possible they'll adopt OLED sometime soon? If not, why not? Does LG own all the viable tech for manufacturing OLED TVs? Is licensing impossible?

Seems crazy to just sit by and lose the most profitable segment if it's at all possible to turn it around. I know they're betting on microLED but that seems implausible for a TV in, say, 2 or 3 years. In the meantime, other TV makers will adopt OLED panels and Samsung could fall further behind.

Really confused about their thinking here.

There was this news that the Samsung CEO resigned and that there might be a fresh start with new perspective...so wait and see what happens. Current direction is all about sticking with Edge Lit LCd no matters what.

It's pretty clear that LG has some amount of IP preventing another company (especially one in Korea) from easily duplicating what they've done legally.

It's also pretty clear that Samsung understands it won't catch LG with a me-too technology given LG's (1) formidable lead (2) progress towards completing enough fab capacity toward essentially having majority share of the high end.

This leaves Samsung with a couple of choices:

1) Make LCD better.
2) Make OLEDs using a new, much cheaper, technique such that it can launch them at prices comparable to LG and then lower prices more quickly than LG will.
3) Make another technology work, e.g. emissive quantum dots.

None of these are good choices. No amount of magic hand waving makes them good choices. Ergo, Samsung has a dilemma.

Or 4) Do like other brands are doing. Have LG supply OLED panels.

Except that there is a deep-seated and intense rivalry and animosity between Samsung and LG.

Nonsense. Business is business.

"LG Display Co. has scored a deal to supply television displays to rival Samsung Electronics Co. from as soon as this year, people with direct knowledge of the matter said."

"LG Display, a major supplier of panels to Apple Inc., will replace a venture between Sharp Corp. and Foxconn Technology Group as a supplier to the world’s biggest TV maker, said the people, who asked not to be identified because details of their agreement haven’t been released. LG Display and Samsung reiterated comments from earlier this month that they are in talks on LCD supply without elaborating."

The LCd and the OLED situation is different. OLED is a new TV technology and there is only one OLED panel supplier..LG. Plus Samsung came up with their own OLED TV but that didn't work out well. Samsung did not do the obvious which is set their pride aside and start buying OLED panels from LG..they are not ready to do that yet..must be very humiliating...

I think it's absolutely hilarious watching that haughty juggernaut squirming as it bleeds red.

Theverge is tearing the OLED display of the new V30 apart. Uniformity problems. Seems like LG has to climb up the learning curve much further. One can clearly see that samsung still has more experience since they are producing OLED for much longer. A shame that they did not opt to license the kodac patents to produce WOLED.

Samsung does not have an OLED TV panel of their own to market now. LG is already supplying them with LCD panels. LG is also supplying other brand names, Sony Panasonic etc, with OLED TV Panels. I don't know why you feel that Samsung can't obtain them the same way. You have said nothing that makes the case for why they can't.

LG isn't providing them LCDs for their flagship models, however, so it's not a question of can they but rather will they accept such an agreement? The Korean Chaebols tend to be prideful entities and the one that runs Samsung would have to save face after downplaying OLED TVs for 5 years.

I did not say that they can't. I said that the obvious thing to do after the Samsung OLED TV adventure, 2013 KN55S9C, was to buy LG OLED panels instead..maybe even start launching some limited scale models with those panels. They had over three years to do that..has not happened....instead they have been focussing on the LCd QD thing all this time. They are currently unwilling to use OLED TV tech which is not theirs, korean rival LG being the owner of the OLED TV tech that does work certainly complicates things.

For a minute I thought I was reading a review of LG's OLED TVs. Same old problems.

"Areas of the same color on the V30 appear blotchy: when I open up a Google Keep note, I don’t get a flat white canvas as I should, but instead I see streaks of gray, looking as if there’s an inconsistent backlight. This being an OLED display, there’s no backlight to speak of, so it’s just poor brightness uniformity across those light-emitting diodes. The same unhappy effect is even more pronounced with darker grays and colors like navy blue, and it’s amplified by the V30’s apparent inability to render color gradations smoothly. Gradients appear grainy and I see unpleasant color banding, exactly the same issues that Ars Technica encountered with a preproduction V30 device last month."

Google is probably going to have a disaster on their hands in a few days because they went with LG to supply panels for their Pixel2 phones as well.

Aren't mobile OLED displays and TV OLED displays built on different technologies? If not, I don't see why Samsung can't scale up in size.
