Why do backlight LEDs burn out and go blue?

I know several different people with OLED TVs that are several years old and holding up well so far, they look absolutely fantastic too. They seem to hold up pretty well on the higher end smartphones too, but there are also a lot of lousy OLED displays that are notorious for failing.

The old CRT rear projection TVs were prone to screen burn too but it is not normally a problem with most content. Unfortunately all of the broadcast channels have those stupid logos in the corner now and I've seen those burn into displays. Those logos are the reason I stopped watching broadcast TV.

I have never and will never buy an OLED anything as long as I live. They exaggerate  the pros and hide/deny the cons until the cows come home. I’d rather have LCD than a half-hearted stop gap technology.

That's a very close minded statement. Technology improves all the time and the day might come when OLED displays become highly reliable and better performance than LEDs. You just don't know what will happen. I'm pretty sure some electric car owners, said the same thing about EVs in the past.

They’ve had plenty long enough to improve - decades. They’re #%#% end of. The industry is moving away from OLED, I can’t recall what to, but this is a tacit admission of how crap they are in one terrible flaw where the colours burn in and one colour dies faster than the others. Good riddance.

So what? That means nothing. Electric cars were invented well over a century ago, before the cathode ray tube. You can't predict the future.
