Ahead of the iPhone’s 20th anniversary in 2027, leaked information suggests Apple is internally testing its largest-ever display — physically measuring 6.96 inches, potentially marketed as a “7-inch class” panel — with the same aspect ratio as the current iPhone 17 Pro Max. Which specific product will use this display remains unconfirmed. The anniversary model is also rumored to potentially feature curved, edge-to-edge glass as part of Apple’s long-rumored “single slab of glass” design vision.

Outlook and Analysis

1. Limits of Single-Source Leak Reliability
This information originates from a single Chinese leaker (Digital Chat Station), who reportedly admitted not knowing the panel’s exact intended use. As 9to5Mac noted, many prototypes that exist within Apple’s supply chain never make it into shipping products — meaning it’s premature to conclude this 6.96-inch panel will definitely appear in the iPhone 20 (or 19 Pro) Max. That said, given Bloomberg’s earlier reporting on Apple developing two anniversary models for 2027, the rumor isn’t entirely without foundation.

2. Resuming a Display Growth Trend Stalled Since 2024
After the Pro Max grew from 6.7 to 6.9 inches with the iPhone 16 lineup, both the iPhone 17 and 18 Pro Max have held steady at 6.9 inches — effectively pausing the screen-size arms race. Testing of a 6.96-inch panel suggests this plateau could break again around the 20th anniversary. Notably, the likely approach of thinning bezels to minimize overall device size growth suggests Apple is seeking a balance between larger displays and preserving grip comfort and portability.

3. Three Possible Scenarios for the 20th Anniversary Model
Reports outline three possibilities: (1) the radical redesign simply becomes next year’s standard Pro/Pro Max lineup, (2) Apple releases a separate commemorative model akin to the iPhone X, or (3) Apple skips directly from “iPhone 18” to “iPhone 20” for naming purposes. All three scenarios share the common thread of Apple aiming to maximize the marketing significance of the 20th anniversary — and under any of them, the 2027 lineup is likely to see the most substantial design shift in recent years.

4. The Samsung Curved-Glass Collaboration Claim
Digital Chat Station’s separate claim that Samsung is developing a shallow quad-curved, polarizer-free display for Apple — if accurate — would mean Apple is once again leaning on its chief rival Samsung Display’s advanced panel technology. However, as the article itself notes, this claim isn’t directly linked to the 6.96-inch panel report, so the two pieces of information should be treated independently.

5. Usability Concerns
Given that the Pro Max is already quite large at 6.9 inches, further growth raises legitimate concerns about one-handed usability and pocketability. Even if Apple offsets this through thinner bezels, a physically larger screen will likely require a somewhat wider chassis — setting up a potential tension between users who favor larger displays and those who prioritize a comfortable grip, which could shape consumer reception going forward.

6. What to Watch Next
As this remains a single-source leak, the key marker of credibility going forward will be whether additional independent sources corroborate this panel and link it definitively to a specific 2027 model.
