If you're already saving up for next year's 20th-anniversary iPhone, be aware that the version Apple ships in 2028 could be the one you actually end up wanting.
Apple is said to be introducing a display that curves down around all four edges of the device for a borderless visual experience, and it's leaning on new technologies to achieve it, but in a step-wise fashion. According to Korea-based ETNews, Apple is planning a two-stage rollout of the "four-edge bending" OLED display that is reportedly set to debut on the 2027 commemorative model.
The first version is set to use a magnesium-silver alloy in the cathode layer, but Apple's initial solution could introduce image distortion and brightness loss in the curved areas. Apple is apparently fine with that compromise for the anniversary launch, but it's already innovating to fix the issues.
A year later, with help from suppliers Samsung Display and LG Display, Apple plans to swap in indium zinc oxide cathodes, according to the latest report. Because IZO is more transparent, the 2028 model should have less distortion, more even brightness, fewer heat issues at the curves, and even narrower bezels.
In other words, early adopters will get the historic design and a few visual quirks, but if you're more patient, you could get the next-gen version with a cleaner panel, with curved edges that look better in direct sunlight.
For the all-important commemorative model, Apple is also said to be aiming for a display with no cutouts, but getting the Face ID system and the front-facing camera under the OLED panel may turn out to be a challenge too far, given the current state of display technology.
Either way, if Apple's curved-panel development plan pans out, the 20th-anniversary iPhone will likely be the model to admire, but its 2028 follow-up may be the one to buy.
