Get ready for a major shift in iPhone design—Face ID without the Dynamic Island could finally become a reality with the iPhone 18. But here's where it gets controversial: while Apple is reportedly laying the groundwork for this change, the path to a truly uninterrupted screen is far from straightforward. Let’s dive into what this means for the future of iPhone design and why it’s sparking so much debate.
Apple is pushing the boundaries of display technology by requiring under-display infrared (UDIR) technology in its upcoming high-end OLED panels. According to a recent Korean industry report, this move is part of Apple’s preparation for the iPhone 18 Pro, potentially reshaping how Face ID is integrated into the device. But this is the part most people miss: UDIR isn’t just about hiding sensors—it’s a critical step toward reducing visible front-facing cutouts, though it doesn’t guarantee a completely seamless screen just yet.
Under-display infrared: What’s the big deal?
UDIR involves relocating the infrared sensors beneath the OLED panel instead of housing them in a notch or the Dynamic Island. For context, Face ID works by projecting infrared light to create a detailed depth map of your face, which is then matched against encrypted data stored on your iPhone. To achieve a cutout-free design, these IR components must function flawlessly through the display stack—a challenge UDIR aims to address.
However, enabling this technology doesn’t mean it’s ready for prime time. Apple could introduce it gradually, hiding some sensors while leaving others exposed. For instance, a smaller Dynamic Island or a simple camera opening might still be part of the plan, aligning with earlier rumors and supply-chain discussions. And this is where it gets even more intriguing: despite years of speculation, none of these concepts have made it into a shipping iPhone design—yet.
Why Samsung and LG are key players
Samsung Display and LG Display are reportedly the only suppliers capable of meeting Apple’s stringent requirements for both LTPO and UDIR technology at scale. Their specialized materials and manufacturing precision are essential for overcoming the challenges of infrared absorption and scattering in OLED panels, which can hinder sensor performance and increase production risks. Apple’s reliance on these companies highlights the complexity of integrating advanced features into its premium devices.
The unresolved question: When will under-screen Face ID arrive?
While UDIR suggests Apple is paving the way for under-screen Face ID, it’s not a done deal. Face ID relies on multiple components—an IR flood illuminator, dot projector, and receiver—working seamlessly together. Hiding these beneath the OLED panel without compromising accuracy, speed, or reliability, especially in low-light conditions, remains a significant hurdle. Past reports have repeatedly pushed back timelines, with some suggesting smaller cutouts or partial transitions instead of a full under-screen solution.
Apple’s history of prioritizing performance over rushed hardware changes adds another layer of uncertainty. Remember Touch ID under the display? Despite years of rumors, it never materialized. Similarly, Face ID itself evolved gradually after its initial launch. The Dynamic Island, for now, remains a functional compromise, balancing sensors, cameras, and interface elements.
So, what’s next?
UDIR points to Apple’s long-term vision for a more seamless iPhone design, but the timeline for this transition is anyone’s guess. Here’s a thought-provoking question for you: Would you prefer a gradual evolution of Face ID with smaller cutouts, or are you holding out for a completely uninterrupted screen, even if it takes longer?
