iPhone SE (3rd gen) display
The iPhone SE (3rd gen) ships a 4.7-inch panel at 750×1334 — 326 pixels per inch. Like most modern phones, it renders the interface at a scaled-down logical resolution, so websites see a much smaller viewport than the panel's native pixel count — that's the device pixel ratio at work.
The last home-button iPhone (2022): a 4.7-inch Retina HD LCD at 750×1334. Its 326 PPI matches the OG Retina density Apple introduced in 2010 — the smallest screen still in wide circulation among iPhones.
