Lenovo ThinkPad P16s G2 AMD review: Power plus OLED inside this workstation laptop

[dvsdv]

I sympathize in advance with the eyes and nervous system of all owners with such an AMOLED screen with a monstrous PWM at 60Hz...

There is no scientific evidence PWM affects anyone.

Here's work from a researcher at Samsung Display that proves this is a problem: www.tandfonline.com/doi/full/10.1080/15980316.2021.1950854

And here is a quote from there:
"...since the IEEE Standards PAR1789 was established for LEDs. In the said standards, percent flicker (1) has a maximum level of 100%, and the frequency that satisfies the low-risk level is 1,250?Hz or higher... "

"According to Table 1, the OLED display did not meet the criteria when it was at a low luminance level at a distance of 1 cm."

"Generally, the viewing distance of smartphones is greater (mean = 33.95 cm, SD = 5.90 cm, range 19.0−51.3 cm) than that of the smartphones tested in this research [Citation13,Citation14]. Besides, as the PWM frequency increases with the development of technology, the effects on the human body of the flicker of OLED displays are expected to become more insignificant."

So, as the article says, if you watch it from a distance of 1 cm or less, with very low brightness in the dark, yes it is in fact harmful to some degree. Pretty much nothing that anyone with a laptop is ever doing.

PAR1789 is from 2010 and latest paper it cites is from 2005. Half of it is about epilepsy and another half is the fact some people had headaches because of fluorescent lighting. It is very badly proven and it's using exactly one study for "headache and eye strain" from 1989, which is obviously not about PWM, but again, fluorescent lamps flicker at 50(100)Hz (see Appendix). Also PAR1789 states that there's no evidence of adverse effects for flicker <165Hz at all.
Go back to school.

A stupid amateur who doesn't understand anything about the topic climbs in with comments.

Change your pants you've shat yourself.

It's ok Niko, you can't read, that's no crime. You have 50 different names here after all...

The shameful NB team has banned NikoB nickname

Finally.

And it wasn't me who started this

Lies. Moderator of german part of forum told you to stop posting in english and you've started posting the same message over and over because you are not a mature person. I was there.

Well, dude, you read the exact opposite in the conclusions. You are clearly inadequate, because in the quote provided by my link, it is directly admitted that there IS an effect on the eyes and nervous system and they are trying to reduce it, i.e. it is written in black and white - all modern AMOLEDs are 100% harmful to vision and especially the nervous system of a person.

Q.E.D.

And this is without references to articles where harm has been clearly proven in numerous tests with animals.

I'm sure the Samsung researcher is clearly smarter and more competent than you, amateur, so he clearly pointed out that there are problems and it's irrefutable.

[lol]

You better admit you do not know english and haven't read and understood the link in full.
