The nexus s and the note 2 dont have the rest of the pixels on.
But you can see, even the black pixels, lit up in a dark room which would make Andrex post make sense:
If any pixels are on, the entire screen uses a tiny bit of power and it emits a small amount of light. However, black pixels in this state use far less power than normal colored/white pixels.
So it's on and uses less power? I know about using certain colors that use less power so it's like that instead of turning it completely off?
The Galaxy Nexus never had pixels completely off which confused me. The GS4 does. I remember someone saying that the GN was made that way because they found out that always having the black pixels be on at a lower power actually increased battery life, but then why did they switch back to completely off for the GS4?
The GS4 turns it completely off? Hmmm I need to see one now
