I don’t mean BETTER. That’s a different conversation. I mean cooler.

An old CRT display was literally a small scale particle accelerator, firing angry electron beams at light speed towards the viewers, bent by an electromagnet that alternates at an ultra high frequency, stopped by a rounded rectangle of glowing phosphors.

If a CRT goes bad it can actually make people sick.

That’s just. Conceptually a lot COOLER than a modern LED panel, which really is just a bajillion very tiny lightbulbs.

    I’m not crazy old, but I’m old enough that the supermarket I went to as a kid had these at all the checkout aisles and the cashiers would use them to send cheques/reciepts/ whatever.

    It was awesome to see.
