ELI5: How is it that large LCD flat panel displays have gotten so cheap?. I remember hearing 20 years ago that the LCD displays were created from a single crystal, but this can't be possible for the 100" panels now available. What advancement in manufacturing made this possible?

I bought a 23inch HP w2338h for $220 10+ years ago and this bitch is still going strong. Even after many moves and getting banged up a bit, there is not a single scratch/dead pixel. Now it's used as a secondary monitor with my primary being an HP Pavilion 27xw that I paid around the exact same price for($200+). I've never had a single issue how of any of my HP monitors. I picked up another HP monitor that is like the small version of the HP w2338h but only a 17 inch that I use on my mining rig(paid $5 for it at a yard sale).

We also have two 27 inch 4k Dell displays on another computer that's obviously higher quality but was much more expensive.

Never in my 30+ years of existence have I had an LCD monitor go out or have dead pixels.
