The science behind the Nokia Lumia 900's screen quality

One of the many things that stood out in our review of the AT&T Nokia Lumia 900 is how good the screen looks. Nokia is using ClearBlack display technology with the Lumia 900 that definitely makes a difference.  But why?

In a recent interview with CNET Raymond Soneira, president of DisplayMate Technologies, explained why ClearBlack display technology gives the Lumia 900 such a nice screen.  Soneira explains that reflectance of a screen can degrade the sharpness and color quality you see. It may be nice to touch up your make-up or comb your hair from your Windows Phone screen's reflection but it doesn't help with screen quality.

Nokia manages to address this issue with the ClearBlack technology and circularly polarized glare suppressing optics. The polarized optics disrupts the reflections, minimizing tier influence on image quality. According to Soneira,

"The Lumia 900 has the lowest screen reflectance of any mobile device I have ever measured, 4.4%, which is almost forty percent lower than the iPhone 4."

DisplayMate Technologies also found the reflectance rating of the Lumia 900 to be noticeably better than that of the new iPad which is rated at 9.9%. Science asides, the bottom line is that the Lumia 900's screen looks really good.
