But I don't see much in terms of planned obsolescence, when company like LG give you 5 years of warranty for you TVs that no burn-in will happen. We will probably get there with OLED monitors to eventually, certainly before we ever get something new like microLEDs.
Bit of an aside but 5 years is a
terrible lifespan for a TV. I would consider 10 years on the shorter end. A 5 year warranty for an appliance / device that historically people can keep using for 20+ years is not a selling point to me. I had a like 30 year old tiny CRT TV in my room as a teen when my family finally upgraded to a "nice" 27 inch for the living room (my, how things have changed for the better in that regard).
Modern TVs are better in a million ways but it's pretty inarguable that most modern home devices (TVs, fridges, washers, etc.) have either intentionally shorter lifespans, or shorter lifespans through lack of effort of the companies. Either way is bad and we should 100% demand better. Planned obsolescence through 0 investment into durability is still planned obsolescence even if big corpos don't say "planned".
I bought a 65" 4K TV like 5 years ago and I honestly would be happy to use that as my main TV until I die or some crazy hyper-3D-now-also-cleans-your-house tech comes out. But there's almost no chance it'll last as long as previous generations of TVs did, which sucks for the environment most but also consumers.
Edit: I just remembered we had to buy a new Fire Stick for my GFs bedroom TV, she's had it for like 6-7 years but app "updates" made it so slow most of the streaming apps would just crash when trying to play videos. That's another form of obsolescence, but at least it's a lot cheaper and less wasteful to work around.
