Apple's "ultimate bezel-free" iPhone is waiting on Samsung to finish the screen. Weibo-based leaker Instant Digital revealed October 7 that Apple is holding out for a next-generation OLED technology Samsung internally calls a "full-surround, full-screen display." MacRumors reported the claims on Wednesday.
The concept differs sharply from "waterfall" screens: the main display stays completely flat, while the OLED panel bends sharply downward at close to a 90-degree angle on all four edges and corners. The folded sections would effectively become the sides of the device, replacing the typical metal or plastic frame, with display wiring routed around the edges instead of hiding behind bezels. In theory, the iPhone would look almost entirely screen from the front, with the black border reduced virtually to nothing. The technology could reportedly also enable an iPhone without conventional mechanical buttons — volume and power handled by touch or haptics on the curved edges.
Simple in concept, brutal in execution. The leaker lists the blockers: optical distortion and color shifts at the sharp corners, maintaining the OLED's protective encapsulation through extreme bends, and finding homes for antennas when all sides are covered by display. Earlier reporting from Korea's The Elec flagged two more critical processes: thin film encapsulation (TFE), which shields OLED panels from moisture and oxygen, and optical clear adhesive (OCA) for bonding curved displays — the latter plagued by a "magnifying glass" side-view distortion. Curved edges also introduce structural vulnerabilities on impact — a tough sell for a company famed for durable devices.
The leaker suggests the 20th-anniversary iPhone 20 expected in 2027 could be an intermediate step, rumored to use a less extreme "four-sided quad-curved display" before the full-surround design arrives. Archynetys' intelligence adds that the panel could support a near-7-inch iPhone 20 screen. Shared concept images echo a Xiaomi quad-curved prototype from 2021 — similar in spirit, though Apple wants a fully flat front with the screen merely "folding" over the edges.
This isn't Apple's first run at "zero bezel." The Elec previously reported Apple originally wanted a bezel-less iPhone in 2025 or 2026 (the iPhone 18), with Samsung Display and LG Display developing the tech for years — but the technology never reached production readiness, pushing the timeline to at least 2027. What Apple wants isn't a simple curved screen either: it aims to keep the iPhone's flat screen and angular design, with the display "flowing" down the sides like an Apple Watch — no waterfall-screen distortion, but a true full screen. Whether it happens is now up to Samsung cracking those hard problems.
