The first Windows Phone-flavored Nokia Lumia 800 uses PenTile matrix for its high resolution display. And though the display of this smartphone is rather large, customers are against the usage of that specific subpixel option for the display. I believe these complaints affected the manufacturer’s decision, since the Nokia Lumia 900 uses the original RGB matrix (it is used for most high-end Nokia handsets) instead of the PenTile matrix.
What is the basic difference between PenTile and RGB matrixes? Some users state they do not see any real difference. But those having a sharp eye claim RGB matrix is way better. PenTile matrix uses too many green subpixels in comparison with blue and red, though the megapixel is rather small. In contrast, RGB matrix uses white color in addition to red, green and blue, providing more color while using less power. In other words, RGB is better adjusted to the structure of human vision.
Those, who are used to PenTile technology, won’t note any significant change. But if your vision is sensitive, then you’ll definitely love RGB on the Lumia 900.
