Even sadder is the fact that I bet LG's hand has been forced by Samsung here. If we are to believe what's been rumoured so far, they're coming out with 8K sets without even HDMI 2.1 (which for 8K is needed if one wants native resolution content, although it doesn't currently exist).
The main development roadmap for WOLED is to increase electro-optical efficiency. This single improvement results in:
-increased peak brightness
-decreased aging-rate and increased time to develop burn-in (for obsessive CNN viewers
-reduced power consumption
-ability to deliver acceptable brightnes levels with reduced fill-factor, such as that required for 8K resolution
The point I'm trying to make is that in delivering the improvements that are most critical to WOLEDs future anyway (electro-optical effuciency), 8K screen resolution essentially comes 'for free' and does not require much shift in focus.
The emergence of 8K WOLEDs will give us 4K WOLEDs with higher peak brightness and increased refresh rates (which will result in more effective BFI).
This is all good, and hopefully LG has understood that improving near-black uniformity is part of their bread-and-butter and critical to WOLEDs continued dominance of the Oremium TV segmet.
8K will require refreshing pixels 4-times as fast, meaning native 120fps @ 2160p will probably start as 60fps @ 4320p before eventually achieving 120fps @ 4320p.
That can translate back to 240fps @ 2160 and eventually 480fps @ 2160, which would be capable of delivering plasma-like persistence levels of 2.1ms.
The actual availability of 8K products is far less important than all of the backplane snd eletr-optical efficiency improvements it will drive.
85" and up screens will be going 8K.
55" and 65" screens will be sticking with 4K but with impressive performance improvements.
It's still unclear to me whether LG will promote 75" screens primarily as 4K or primarily as 8K (or maybe both).
I would rather have a very fast (improved motion), very bright 4K 75" WOLED than an 8K 75" WOLED.
Don't be surprised to see LG plunge the improvements they are developing 'for 8K' back into even more impressive 55" and 65" 4K WOLEDs.
A 4K WOLED panel can be manufactured with 8K 'improvements' without adding any real cost.
While the same is true for a QD-enhanced LCD panel, it is not true for it's LED backlight (an improved backlight will add cost).
The trend towards developing ultra-large-screen 8K TVs will reinforce WOLEDs dominance of 55" - 75" 4K Premium TVs...
