Every Apple announcement about a monitor, such as the Studio Display, and every rumor about any new display, always concentrate on the image quality. Sometimes there are other issues such as there being a webcam built in to the Studio Display, but otherwise it's the size, it's the resolution, and somewhere in there will be the words "retina display."

In every way except possibly price, Apple displays continue to get better, and remarkably so. What no Apple display does so far is make sure that only the user can properly see this glorious image quality.

Right now, existing Apple displays — whether LCD or OLED — have very close to a 170-degree field of view. There have to be government and security offices where that has to be stopped somehow, and it would always be good to know that your privacy was being protected.

But anyone trying to look from even slight to their left or right, will either see nothing at all, not more likely a blurry image. This won't stop anyone standing right behind the user and peeking over their head, and that might actually be a serious issue if someone's seat across the office is positioned just so.

There will always be a privacy issue that cannot be controlled by hardware and must be watched out for by the user. But it turns out that Apple does have another idea, albeit one that is seemingly only for regular flat monitors instead of curved ones.

Instead, Apple proposes altering the very viewing angle of the display, presumably at will. The idea is that displays could have what's described as an "electrically controllable filter," which would let the user control just how polarized or not the screen is.

As suggested in the patent, a display using such technology could also have an extra layer of liquid crystal in between these polarizing layers. That liquid crystal element could feature a color filter, letting images with certain colors be limited to just the display user.
