Hold onto your hats, iPhone fans, because the future of Face ID might be about to change in a big way. Imagine an iPhone with a seamless, uninterrupted screen—no notch, no Dynamic Island—just pure display. Sounds like a dream, right? Well, according to recent reports, Apple is reportedly laying the groundwork for exactly that, starting as early as the iPhone 18 Pro. But here's where it gets controversial: while the technology to hide infrared sensors under the display (known as UDIR) is advancing, it’s not a done deal. And this is the part most people miss: even if Apple achieves this, it doesn’t guarantee a completely cutout-free design—at least not right away.
Apple’s display specifications are getting tighter as it prepares for its next-generation premium iPhones. A Korean industry report claims Apple is demanding under-display infrared technology alongside advanced LTPO OLED backplanes. Why does this matter? Because UDIR is a critical step toward reducing those visible front-facing cutouts we’ve all grown accustomed to. However, enabling the technology is one thing—actually shipping a finished product is another. Apple could take a gradual approach, hiding some sensors while leaving others exposed, like a smaller Dynamic Island or a simple camera opening.
But let’s break it down further. Under-display infrared means relocating the IR sensors beneath the OLED panel instead of housing them in a notch or Dynamic Island. Face ID works by projecting infrared light to create a depth map of your face, which is then matched against encrypted data stored on your iPhone. For this to work seamlessly under the display, the IR components need to function flawlessly through the screen stack. UDIR clears a major architectural hurdle, but it’s not without challenges. OLED panels naturally absorb and scatter infrared light, complicating sensor performance and increasing manufacturing risks.
This is where Samsung Display and LG Display come in. These companies are reportedly the only suppliers capable of meeting Apple’s stringent LTPO and UDIR requirements at scale. Their specialized materials and precise manufacturing processes are essential for achieving acceptable yields while maintaining brightness, color accuracy, and durability. Apple has tried to diversify its display sourcing, but when it comes to advanced features, these established OLED manufacturers remain indispensable.
Now, here’s the million-dollar question: Will under-screen Face ID actually happen, and if so, when? UDIR strongly suggests Apple is moving in that direction, but it’s not a sure thing. Face ID relies on multiple components—an IR flood illuminator, dot projector, and receiver—all working in harmony. Hiding these under the OLED without sacrificing accuracy or speed, especially in low-light conditions, is no small feat. Past reports have shown timelines shifting, with some claims pointing to smaller cutouts or partial transitions, while others push a complete under-screen solution years into the future.
Apple has a history of delaying hardware changes rather than compromising performance. Remember the rumors about under-display Touch ID? They never materialized. Face ID itself evolved gradually after its initial launch. The Dynamic Island, for all its quirks, is a functional compromise that balances sensors, cameras, and interface elements. Under-display infrared hints at Apple’s long-term vision, but the timeline remains anyone’s guess.
So, what do you think? Is Apple on the right track with under-display Face ID, or is it biting off more than it can chew? Will we see a seamless iPhone screen in the next few years, or is this just another case of overhyped rumors? Let us know in the comments—we’d love to hear your thoughts!
