Ink jet OLED is finally ready for commercial production!

Apparently TCL (who also bought JOLED if you still remembered) finally managed to make ink jet OLED works and set to make its first production next year! Even better, it's going to use a true RGB subpixel! 

 

I am so exciting for this, maybe an OLED, cheap enough for a disposible monitor and have none of the text problem that plaged all of the current LED offering is finally about to become reality. Korea and Japan also set to invest heavily to come back at the prospect of China OLED too, the next few years is going to be so awsome for a display/TV market.

Will believe it when I see it. Inkjet OLED was "just around the corner"... 18 years ago.

Not sure that's a good thing, there's a reason that's not what's used now, too many drawbacks... Sounds like if it comes it'll be "quantity over quality"

And what are the drawbacks? Having anything OTHER than RGB is considered a drawback.

 

I really hope this can bring prices down a lot. JOLED's panels currently are extremely expensive. LG's 32" 4K 60Hz option is around $4000.

Direct RGB emitters suffered from unevenness especially when aging, hence the move to having all emitters be the same and putting filters (or better, quantum dots) in front.

Also RGBW is a "drawback" in color saturation in high brightness, but an advantage in being able to give high brightness at all which is also a complaint when it's not there. Specular highlights and bright spots rarely need strong color too...

The planned relesed is next year, so I guess we'll see. But you're right, it could be significnatly more crappy compare to even WRGB OLED, with worse ABL and significantly worse brightness. But if it's dirt cheap like 300-500 range that's still some very attracitive option.

Yes, the white subpixel is needed. Otherwise current OLED TV's would probably top out at around 150-200 nits at best. But even with the color washout at high brightness the white subpixel helps deliver a much better HDR image than if it wouldn't be there.

 

Still, PC gamers are generally of the opinion that anything other than the standard RGB layout is bad, even though we're realistically only talking about an issue that can be noticed when pixel peeping.

You need a lot of saturated bright spots and highlights. Explosions, fire, reflections on colorful objects, and many more look better even on current QLED TV models than OLED TVs. Color volume is important and the lack there of is a drawback for WBGR (not RGBW) OLEDs like LG's panels. This is why QD-OLED looks so much better, not necessarily the slight boost in brightness.

 

The point at which colors begin to wash out on current OLED TVs is much lower than you'd think. At around 150 nits and up the white subpixel is already at work.
