A Korean supply‑chain leak suggests the upcoming iPhone 20 will debut a four‑sided bending display that skirts the bezel entirely. The document warns the first‑generation panel could suffer visual distortion because its cathode layer uses a magnesium‑silver alloy. Apple appears willing to ship this imperfect version in 2027, betting on the novelty of a seemingly seamless glass slab.

Suppliers Samsung and LG are reportedly lining up production lines for the new screen, while the report notes a second‑generation panel slated for 2028 will replace the magnesium cathode with indium‑zinc‑oxide transparent electrodes. That material swap should eliminate the distortion risk and restore luminance across the curved edges, delivering the true bezel‑free experience Apple has been courting since the iPhone X.

Earlier leaks hinted at a special‑edition 20th‑anniversary iPhone launching next year, possibly under the Pro or Pro Max badge. Whether Apple markets the device as a flagship or a limited‑run celebration, the four‑sided glass ambition marks a significant step toward its long‑term vision of a single slab of display. Consumers may need to decide if the novelty outweighs the early‑model’s visual flaw.
