[hackaday] Using an LCD’s poor viewing angle to your advantage - Page 2

So if the screen is capable of displaying an image from the side then why can't it display the original image from that angle?

I like the idea of changing the numbers round on the PIN keypad and obscuring them from the side. I occasionally work front desk at a climbing gym and I find it far too easy to read peoples' PINs as they type them in. Most people don't even bother covering them. This would make it very hard to read them without being directly behind the person.

It would also make it harder to withdraw money when drunk, which would be useful for a few people I know...
