- 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.
Here is how Nokia's ClearBlack AMOLED display technology works

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.....
