Nokia introduced a lot of smartphones, with their ClearBlack AMOLED Display (Lumia 900, Lumia 800, X7 and E7).
We have learned already that Nokia use a polarizing filter that block the incoming light and so Nokia can reach the goal for a better outdoor quality.
At the Nokia Blog the company explain how it work in detail:
- It 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.
Super-Amoled vs ClearBlack Amoled
Samsung use nearly the same technology with Super-Amoled. Here are some pictures about a comparison:
