Apple urges its OLED suppliers to adopt borderless designs

Apple is reportedly asking its OLED suppliers Samsung Display and LG Display to develop borderless OLED panels. The move is two-pronged — initially, Apple wants to reduce the bezels on this year’s iPhone 23 Pro models — and then, likely a few years later, Apple wants to go all-display. That means no camera cutout and the thinnest possible bezels.

The word “could” is key. Right now, Apple’s bezel-less plans face some key hurdles. One of these is the under-display camera (UPC) — the outer membrane layer is not yet thick enough to accommodate the under-display camera. Then there is thin film encapsulation (TFE), which protects the OLED from moisture and oxygen. It is made by stacking an inorganic film and an organic film – the inorganic film blocks moisture and oxygen, while the organic film blocks the gaps in the inorganic film.

The third issue is that Apple’s obsession with keeping the iPhone’s flat display makes it difficult to bend the screen’s circuitry along the bottom bezel. Apple reportedly doesn’t want a curved display because it has a magnifying glass effect around the edges, and it believes curved screens are more likely to break.

These are challenges for Apple’s display suppliers, and mean a truly bezel-less iPhone is still years away.
