20th Anniversary iPhone Tipped to Use Brighter, Thinner OLED Panel

Apple for its 20th anniversary iPhone will adopt a Samsung-made OLED technology called COE (Color Filter on Encapsulation) to make the display brighter and thinner than previous panels, reports ETNews.

All Screen iPhone 2027 Feature 1
In a traditional OLED panel, a polarizing film sits above the display to cut reflections and improve contrast. The drawback is that this film also absorbs some of the OLED's own light, reducing brightness and efficiency. With COE, Apple would remove the polarizer entirely and instead apply the color filter directly onto the OLED's protective encapsulation layer.

The result would be a thinner display stack that lets more light through, delivering higher brightness without requiring more power. Removing layers would also mean less thickness overall, potentially contributing to a slimmer iPhone design.

However, Apple's challenge is that without a polarizer, reflections and glare control become trickier, so Apple will likely have to rely on advanced coatings and pixel-level materials to maintain outdoor readability.

If Apple brings COE to its 2027 iPhone – the 10th anniversary of the iPhone X – it would be the first use of the technology in a non-foldable device from the company. Meanwhile, Samsung is expected to expand COE to its Galaxy S26 Ultra in 2026. Samsung first rolled out COE in the Galaxy Z Fold 3 back in 2021 to contribute to the device's thinness.

Apple is reportedly considering a radical redesign for the 20th anniversary iPhone that could feature a completely bezel-less display that curves around all four edges of the device. The model is expected to be preceded in 2026 by Apple's first foldable iPhone.

Why are we still using that dumb all-screen phone as a render of the 2027 iPhone? Does anyone really expect that will happen? They can't even get the camera pill to the size the competition has used for years now. What makes people think this is going to happen in 2 year? Aside from how fragile that would be, why would anyone want that?

I agree with you on everything other than the “Camera Pill” comment. There is a very good reason why the Dynamic Island is there. Android users likely do not believe it, but FaceID is far more secure than any authentication available for Android and that is why the “Camera Pill”, as you call it, is there. They will match the lackluster competition once the technology allows FaceID to be small enough. Android’s face authentication is similar in marketing only.

Not a fan of a screen that curves on the edges…

Aside from that, let’s hope they use this new OLED technology on the regular iPhone 18, and that they improve even further the “reduce PWM” feature so that they manage to eliminate almost all of the pulses or flickers. The current iPhone 17 seems to do a good job but still flickers a bit.

Just having that option on the iPhone 17 signals that Apple is aware of the issue, and gives me hope that Apple is taking ocular health into account and we may see improvements in that direction. Let’s cross our fingers.
