I was born in ’99, so I grew up in the last age of CRT TVs. I’m wondering why they were built to have curved screens. It’s not like flat screens weren’t a thing, because films were projected onto flat screens in movie theaters until IMAX became a thing. But I wonder what about cathode rays made curved screens a necessity until plasma, LCD, and LED televisions came about.
In: Technology
Because they were lit by a beam of electrons, and the aiming mechanism is a powerful magnet. Having the screen equally distant from the beam point was the best way to get it focused on the screen.
I realize this isn’t “ELI5” ish, but….I couldn’t think of a way to explain it better.
