@DanHulme I purchased an android device on contract and now plan to unlock it from a non-US territory. So is it legal or something illegal. As DMCA is a US law so it will not be applicable on a non-US territory. So do you suggest me to go ahead and get it unlocked by purchasing unlock code / unlocking it through other means .
How does that overlay work then, other than "reducing power fed"? If it's using the "color-change approach", it works on OLED, but not on LCD (like described).
Thanks for the details, just updated my answer with them: Great additional info that should be there!
May I ask if the downvote was yours – and if so, whether it was for "incomplete data" or "misunderstanding"? In the latter case, you might wish to "retract" it ;)
I see no contradiction to what I wrote (except for phrasing, where I might not have chosen the best words – I'm no native speaker, you know).
If there's any misinformation in the post, I should correct that (regardless of your downvote – but for quality: it might otherwise mislead people based on the "high rep" of the poster).
> But if it's a software layer reducing brightness, that's something completely different: How should that be achieved other than reducing the "amount of light created"?
@Izzy That's true, and it's fine when you say it like that. It's just that "compatible" and "specifically designed for OLED" imply there are two techniques based on the two kinds of displays, when there's only one technique.
and you've still got the whole "redifying" footnote which is entirely speculation
@DanHulme How other to put that? A filter working by "changing the colors" doesn't save juice on LCD. But I get your point: it still works to darken the display in both cases, and such isn't "specifically designed for OLED". Again I'm at a loss in phrasing...
@Izzy Something like, "Using a filter/overlay like this will make either type of screen look darker, but it'll only reduce power use on OLED screens. On LCD screens, only decreasing the backlight brightness saves power."
@DanHulme Maybe add the term current (time-related) here. Who knows what future brings. I remember having read about things playing with differently colored LEDs to compose a color in a more energy-friendly way than the plain colored LED had allowed for. Not sure whether it was display-releated, though.
@DanHulme That looks perfect! Do you permit me a copy-paste?
