It’s actually a method to reduce reflections on the screen and improve visual image quality, especially outdoors.
CBD ensures that the blacks you see really are just that - black - which in turn enhances the contrast of the display and makes the whole screen much easier to see. This will be especially useful fo apps like Ovi Maps, which are likely to be used outside.
