GSM Arena have been busy with the Nokia N9 and one of their first findings was that the FWVGA AMOLED display is using a PenTile matrix, instead of a regular RGB one.
 

 

It’s the same kind of matrix that we saw with Samsung’s first-gen Super AMOLEDs, where each pixel is composed of two subpixels rather than three. This gives less room for sub-pixel rendering and reduces the effective resolution, when displaying super fine detail.

Let’s just make one thing clear – with a pixel density of 251 ppi, the Nokia N9 still has an amazingly sharp display and it’s not that easy to spot the side-effects of the PenTile matrix. Still, if you look really closely, you will be able to spot the familiar dottiness.

Now here’s the promised proof – a close-up shot of the Nokia N9 pixel grid. Notice that each pixels consists of one green sub-pixels and one double-sized subpixel that’s alternating between blue and red.
