What was the first iPhone to use an OLED display?

The iPhone X was the first iPhone to use an OLED display.

Released on November 3, 2017, the iPhone X introduced Apple's 5.8-inch Super Retina HD display. Unlike the LCD panels used by earlier iPhones, OLED pixels produce their own light, allowing the phone to show deeper blacks, stronger contrast, and a thinner display assembly.

The screen was part of a broader redesign marking the iPhone's tenth anniversary. The iPhone X removed the traditional Home button, used a glass-and-stainless-steel body, and replaced Touch ID with Face ID. Its edge-to-edge design also introduced gesture-based navigation that later became standard across Apple's flagship iPhone line.

The iPhone XS is a frequent wrong answer because it was the next generation and also used OLED. However, it followed the iPhone X rather than introducing the technology to the iPhone family. The iPhone 8, released alongside the iPhone X in 2017, retained an LCD display. Apple's OLED adoption began with the premium anniversary model, while LCD screens continued on less expensive iPhone models for several years.
