> The iPhone XR will offer an LCD screen with a resolution of 1,792 by 828. This would give it a resolution of around 324 pixels per inch, slightly below the iPhone 4’s 326 ppi.

This is sad.

How so? It has sufficiently high PPI, you won't be able to see individual pixels. Going higher is pointless.

If going higher is pointless, why does the iPhone XS has a PPI density of 458? They should have stayed at 326 in that case as well.

OLED needs higher pixel density to achieve the same level of “sharpness”. That’s why LCD’s can looks as crisp at much lower PPI.
