In the EU, everyone who could afford an EV probably already has one. The rest will buy what they can afford and can charge.
I'm not planning to buy a new car though, as mine is only 8 years old and still working fine. I'll check again when repairs start to get more expensive, maybe in a few years.
So is it something like "only produces light where needed on the screen" or "uses the least energy when turned off" or "does image processing for x format with the least energy" What are they measuring here?
It's the electricity usage when running the TV. There is e.g. quite a difference between LED and OLED.
TVs is also quite a large part of electricity usage in a household. Maybe 75 - 150W running a few hours a day. You have to keep in mind that not many people have PCs, NAS, etc. running 24/7.
