Here is how Nokia's ClearBlack AMOLED display technology works
- It [the light] hits the linear polariser, this vertically polarises the light. (Polarising means – roughly – aligning the wave vibration in a particular direction).
- Then it hits the circular polariser retardation layer. This converts the light again, making it right-circularly polarised.
- Then it hits the screen and bounces off it, switching the rotation of the light to leftist.
- It goes back through the retardation layer. When this happens, the light becomes horizontally polarised.
- Finally, it hits the linear polariser, since the light is horizontally polarised at this point it can be blocked entirely by this optical solution.

Well they should put a solar panel in the last layer so when the light is blocked from reflecting off, it is absorbed and converted into energy t hat will give you extra battery. Or is it wishful thinking? lol

Wishful thinkning. Infact, nokia was testing a solar charging phone (you'll probaby have to look theough Nokia Conversations history to find out about it) but decided it wasn't vaible after highly unreliable results.

Wow, a very late article. When I'm curious about a subject like this, and I don't find it on phonearena, I Google it. That's exactly what I did... A few months ago.....
