20th Anniversary iPhone's Curved Display to Improve a Year Later
MacRumors • • general
Key Points:
- Apple plans to debut a "four-edge bending" OLED display on its 20th-anniversary iPhone next year, featuring a screen that curves around all four edges for a borderless design.
- The initial 2027 model will use OLED technology with a magnesium-silver (MgAg) alloy cathode, which may cause some image distortion and brightness loss on curved edges.
- In 2028, Apple aims to upgrade to next-generation transparent electrodes using indium zinc oxide (IZO) cathode materials, expected to reduce distortion, improve brightness uniformity, and enable narrower bezels.
- Samsung Display and LG Display have been alerted to prepare for this two-stage rollout, with LG investing approximately $790 million in OLED infrastructure likely tied to this development.
- Samsung is assessing whether existing OLED production lines can support the new technology or if a dedicated line will be necessary for mass production.
