Apple Plans Four-Edge Curved OLED for 2027 iPhone

Apple plans to introduce a four-edge bending OLED display on its 20th anniversary iPhone in 2027, marking one of the device's most significant design changes since the iPhone X debuted a decade earlier. The screen will curve around all four sides to create a nearly borderless appearance, according to supply chain reports. However, the initial version will use a magnesium-silver (MgAg) alloy cathode layer, which may cause image distortion and brightness reduction at the curved edges.

Reports indicate Apple is prepared to accept these limitations for the 2027 launch to meet the anniversary timeline. Suppliers Samsung Display and LG Display have been alerted to produce the panels, with LG announcing a 1.106 trillion won (about $790 million) investment in new OLED facilities believed to support this technology. Samsung is evaluating upgrades to its production lines.

A more advanced iteration is slated for 2028 iPhones, switching to an indium zinc oxide (IZO) cathode material. IZO's greater transparency is expected to minimize distortion, maintain consistent brightness, and reduce heat issues in the curved areas, while enabling even thinner bezels. Both display makers are preparing...
