I can only use screens without PWM since I suffer from migraines (with aura. Horrible thing to be honest).

After a while asking what was wrong with me I found out about PWM and ditched my OLED screen phone and cheap LCDs from my house (never replaced them, mind you).

Portable OLED screens will probably improve over the years - as everyone else already mentioned - specially when portable device users age and some get migraines too.

Also, the user base differs from say, smartphone users. For now, people like me need to be extra careful to avoid the consequences of the first generations of such screens. That's where notebookcheck's reviews come in handy.
The screen section of the reviews is a lifesaver.

Just to be clear, the 60Hz dip you see on oled displays is NOT pwm. It's part of how the image refresh works. All oled panels have that 60hz graph at maximum brightness, but the NARROWNES of the dip makes it practically inconsequential.

Pwm kicks in usually at some lower brightness level, eg. 75Hz on a Galaxy Book 12. The frequency is always higher than 60Hz in all models I have seen reviewed. Usually around 240Hz. Also the deepness and width of the modulation makes a lot of difference in how much such effect can be problematic, and this is often ignored in notebook check reviews. that being said, no PWM (or pwm at very high freq with lowodulation width) is always better of course.

Refresh rates can only go so far. A 70 hz CRT is still smoother than a 240 hz IPS because the image is not persistent. If OLED can emulate CRT by turning completely off between frames, even at 60 hz, it will be the king of smooth.

All that I want is a 27 inch 144hz 1440p OLED monitor... 240hz would be a dream... And I ll never look back...

People say about OLED burn ins, but IPS with time start to pop up bright spots... So...

There are certainly always trade offs between differing technologies.  However, as others have noted, the info here about OLED refresh rates is wrong.  I was convinced I was reading a 5 year old article.  I'm no computer screen guru but I do know TVs.  I have an LG OLED 4K TV with a 60Hz refresh rate.  I've had lots of high end TVs.  By FAR, this is the best display I've ever seen outside of display models at CES and such.  And, it's only getting better.  LG 2019 OLED TVs are available with variable and 120 Hz refresh rates with 4K OLED even via HDMI.  If any technology can accomplish looking better than my 4K LG I will gladly acknowledge it.  But I suspect the only thing that will be able to do that in the near future will be LG's $44K 8K OLED. 

Can't wait for MicroLed which should give us that CRT response time!! Both Microled and CRT have nanosecond response times. People always say "there is nothing faster than the speed of light", well both technologies uses solely light to display the picture. CRTs are so fast that you can track the background layers with 0 motionblur in Sonic The Hedgehog while going Sonic fast!!

I just have to say - what? Ips is not good for high refresh low ms gaming, TN panels are.
Oleds are known to have low response time, especially in tvs. All LG OLED panels are 120 hz btw so to say that oleds are limited to 60hz is just bull. The downsides to OLED panels are mostly less brightness and burn-in concerns.

And, on a laptop, battery life. Especially since laptop OLEDs are basically limited to 4K right now.

I just wanted to point out that there are OLED screens with higher refresh rate (OnePlus 7 Pro has 90Hz) and without PWM (Xiaomi Mi9).

OLED? No, thanks, I'll let others to pay extra for OLED and test this first gen on their eyes. I can imagine the amount complains on reddit in 2-3 years about panels burning and latency with scrolling on black background.

No thank you, I like my eyes too much.
That pulse-width modulation flicker at incredibly low 60.24 Hz on OLED displays, at any brightness setting, is a total deal breaker.
Just to compare, the IPS display on my 4k XPS 15 flickers at much higher 1000 Hz only at the brightness lower than 25% (which is never being used anyway).
Hopefully they'll improve the OLED technology in the next year or two, I'd love that super high contrast...

There is one more problem with IPS: backilght bleeding, I would like to buy OLED, even if is slower, also OLED in new laptops are mostly 4K, so this might be reason for only 60hz. Is there any technical barrier for 144hz fullHD OLED?

I'm gonna buy a 15" gaming laptop soon, and I will take OLED without any hesitation. 144Hz+ is awesome but I only need it when I try hard and play game like overwatch. I never launch a competitive game when I'm not at home (with external 144hz screen).
Even with a 144Hz laptop I would not, I don't see me do competitive at launch break or whatever. That's why I pick OLED for gorgeous chilling session on anno, rayman, witcher, movies... etc.
