Explains phone feature with analogyfrom @thespenceryan

Yes 26 Ultra proves Samsung is leading in innovation, but the part nobody's really talking about is how crazy the display really is. You've probably seen the privacy display by now. Turn it on, from the side, the screen looks like it's off. But how they pull this off to me is the wild part. Imagine your phone screen is made up of millions of tiny little windows. Now normally, each window allows light through and sprays light in every direction. And that's why the person next to you can see see your phone screen when they're glancing over your shoulder. So Samsung basically replaced some of those windows with windows that have microscopic blinds. Those windows only allow light to go straight worse, not sideways. But here's the crazy part, each one of those windows can be controlled individually. So the phone can block parts of the screen, all of the screen, or none of it, all from a hardware level. And somehow, this is still a high resolution, high refresh, in screen fingerprint reader, yes pen supporting display. You see, Samsung has been pushing phone tech for over a decade from producing the world's first AMOLED smartphone to the old eye tracking scroll that they had on some of the first Galaxy devices, curved displays, foldables, and now the privacy display. Even if you're not a fan of the phones, we can't pretend they aren't innovating at a level that most brands won't even attempt.
