I love that about CRTs, man.
How the fuck could we invent a tiny pocket sized particle accelerator electron beam gun that magnetically aimed its fire with such precision as to hit every individual phosphor, with the appropriate charge to make the right color, across an entire fucking screen, and do that 30+ times a second (for TV, or 60+ for a monitor)..
Yet the LCD is the high tech fancy monitor when its just a little grid of globs being electronically fired? How did the CRT get invented before the LCD?!
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.
