Nokia’s come up with some pretty innovative technology in some of the phones over the years, and their latest is their “ClearBlack” display screen technology.
Many of Nokia’s phones uses the clearblack technology, such as the new Lumia Windows Phones. Basically it’s a circular polarizer between the LCD or AMOLED screen and the Gorilla Glass, which results in a higher contrast screen with better glare-elimination of reflected light and basically just better readability. According to the post on Nokia Conversations:
There’s both a linear polariser and retardation layers between the surface of your phone and the display. When light hits your screen, this is what happens:
- 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.
Right. Super complex stuff, eh? I definitely love the ClearBlack AMOLED screen on the Lumia 800 and the ClearBlack LCD screen on the Lumia 710 is also pretty good. Have you taken a look at the new Lumia devices yet? What do you think of the Clearblack screens on the latest Nokias?
