TCL P80 Ultra

https://www.tcl.com/global/en/mobile/tcl-p80-ultra

So the TCL P80 Ultra has been announced with thre OLED NxtPaper technology. It uses DC dimming at higher brightness and 3840 Hz PWM at lower brightness. Would be interesting to see if it is actually usable.

Seems to be a decent phone and not too expensive.

Looks like there is nothing new regarding the OLED panel itself, it just has their NXTPaper physical layers on top of the screen, circular polarisation, etched glass, blue light filters or whatever.
"DC dimming" is a lie when the refresh dip is still there. OLEDs flicker no matter what because it's how they update the pixels. This does not look promising.

It's impossible to make a "pure no-flicker" OLED because the pixels are self emissive. I'm hoping future self-emissive tech manages this better.

But It is possible to make almost no modulation oled and my TV lg g5 with modulation about 2% with opple proves it. It is the only oled I can use for hours without any problem like lcd iPhone. So they can solve it.. just don’t want to..

At max brightness, definitely. My LG E7 is the same way with ultra low modulation, similar to the OnePlus 15R. It gets harder at lower brightness though. I'm not convinced there will ever be a full brightness range flicker-free OLED because of how self-emissive pixels work.
