So they are instead working on 4k, or is the partnership over completely?

Well that's disappointing. Had they developed the tech required for mass-production things would have been a lot easier for both companies.

OLED/4k is beautiful. OLED plus 4k res might push people to upgrade from their 1080p LED TV's.

So whats wrong with persuing the tech? Unless you were talking about the companies then wateva. But the tech is good.

Doubt it. I mean even if they get it right first...samsung/LG would soon follow and probably do it better and make it more desireable to consumers.

That's what patents are for.

Patent what? 4k? OLED? Uhm...

they were developing technology gor mass production which doesnt exist

Patent the manufacturing process. They were working on finding a technology to amss-produce OLED. OLED is currently every expensive for everyone who makes it, including LG and Samsung. Their venture was to find a much cheaper alternative, which yes, IS patentable.

Just like you can't patent games, but you can patent process for making games, ie; engines and languages.

Sony even got rid of the OLED that was in the Vita, which was made by samsung I believe

I see. Then my original point still applies.

It wouldnt take too long for the other manufacturers to do the same.
