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.
Turns out manufacturing individual, low-power-draw, micron-sized lights is not easy. Even if it’s conceptually not as cool, it requires much better manufacturing processes and materials.
LCD isn’t LED.
But, confusingly, an LED TV is an LCD TV. An LED TV is just an LCD TV that uses an LED array for the backlight instead of florescent lights. Quantum dot or QLED displays are also just LCDs with a fancy backlight. OLED displays are the ones that actually have glowing subpixels.
