Reliable leaker explains why the Galaxy S23 Ultra display could be harmful to your eyes.
In his tweet, Ice Universe writes,"It's very funny that Samsung Display uses a video to illustrate the harm of flicker to human eyes, and promotes that Samsung OLED screens are flicker-free , but S22 Ultra and S23 Ultra are the most flicker phones. It's so funny." In a follow-up tweet, the Ice Man says,"Oh, by the way, the Galaxy S23 Ultra is also the most eye-damaging screen among all brands of mobile phones.
PWM, or pulse-width modulation, is a technology that turns diodes on and off at various rates. This technique, which turns the display on and off, is how phone screens are lit up. Manufacturers use it because it helps keep costs down allowing devices to be sold at lower prices than they might cost otherwise. A faster PWM means that flickers happen too fast to be seen by the human eye while slower speeds can cause the aforementioned eye strain, headaches, seizures, and eye pain.
The extra S23 Ultra bonus from the link here on top of Samsung’s store credit brings the Galaxy S23 Ultra starting price on Verizon to just $399.99 with a trade. And a 5G plan! Also, you can benefit from a free Galaxy Watch5, free Galaxy Tab S7 FE — or both with your purchase.
