Apple's upcoming iPhone 20 may feature a quad-curved display, but the design has a significant flaw. According to a report from ETNews, the current magnesium-silver alloy cathode layer risks distortion at the screen's edges, reducing overall brightness.
Apple to replace alloy with IZO in 2028
Apple plans to address the issue by replacing the alloy with Indium-Zinc Oxide (IZO) in 2028. Samsung is the exclusive supplier for the initial iPhone 20 display, and LG may join production in 2028. LG is investing 1.106 trillion won (about $741.29 million) in a new facility for IZO cathode production.
The quad-curved design could make the iPhone 20 the most expensive Apple release. However, if the distortion flaw persists, Apple may cancel the design and ship the device with a regular flat panel instead.
The iPhone 20 is expected to launch globally in 2027, with a refined version following in 2028. ETNews reported the display issue, but Apple has not confirmed the details or the launch window.
