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.

    They still use them today in some supermarkets, now they use them to send packets of cigarettes through the store.

      That’s actually a pretty good use. In my local market they send the person to a separate counter.

        Very cool, I’ve never seen the ones that can send a person. Can they breathe in transit?
