Using an LCD’s poor viewing angle to your advantage

In one example they have blurred the financial details on the screen from anyone viewing from the side.

I wonder if that could be iterated further such that all of the screen is blurred from the sides (presumably by dynamically altering the "overlay" to cancel out each color of each pixel).

This would then make a great alternative to a privacy screen for use on planes, etc.

Don't ATMs do something like this, or are they just built to have the shittiest viewing angles ever (which is obviously advantageous for this scenario)?

They have privacy filters, a separate covering that reduces the viewing angle of any screen to almost zero. You can buy one yourself, if you want.
