Apple Needs to Copy Samsung's New Security Smartphone Screen ASAP (wsj.com)

There’s been screen protector film on the market that does exactly this for almost as long as the iPhone‘s been available. Almost 20 years?

When your display fails in viewing angles, we call it privacy screen

Samsung makes the screens for iPhones so they most linely will make this tech available after the testing period with the new phone

They will likely copy it in 8 years and label it innovative.

You could try doing this[0] to your iphone... ([1]).

Currently a lot of smartphone power consumption is used to drive the screen, but only a small fraction reaches someone's eye. This could be used to improve the power efficiency of screens by at least an order of magnitude

I think it's a gimmick that Samsung will cut out in future models for cost savings reasons. Like Samsung ditched the edge displays, or the Bluetooth in their S-Pen, or like Apple ditched 3D touch.

It's a gimmick, it reduces overall brightness when off-angle.

I much rather have a tandem oled screen.

Do people really care if someone looks at their phone like that? Especially when the apps themselves spy on everything you do?

Reading comments here looks like most of the commenters didn't read past the title.

This is not the same as a privacy screen protector. The screen hardware itself can dynamically protect parts of the screen on demand down to pixel level, the OS can then dim only the app or notifications you want dimmed. There is no screen degrading for parts that are not in privacy mode.
