You have somewhat proved my point in that some how 'pixel density' is often used as the go-to stat. It makes no sense to hold this in higher standing than the actual pixel count-- nobody is asking for smaller screens with the same resolution. Simply holding your phone further away would have the same effect as a smaller, more pixel-dense screen. Increased pixel density naturally comes with increased resolution, it is…
The subpixel count is about the same as the iP4 Exactly the same, 1280x720x2 = 960x640x3.
Which means that sppi is lower, since the NP has a much bigger screen.
