Introduction
Apple’s next flagship will feature a stunning screen. According to leaks, the iPhone 18 Pro Max display measures 6.9 inches, uses LTPO OLED technology, and offers a 120Hz ProMotion refresh rate. Peak brightness may reach 3,000 nits, and the always‑on display gains new customization options. This deep dive covers size, refresh rate, brightness, and real‑world benefits.
For a complete overview of the device, read our main guide: Apple iPhone 18 Pro Max .
Screen Size – 6.9 Inches, the Largest iPhone Yet
The screen grows from 6.7 inches to 6.9 inches. Apple achieves this by shrinking bezels and reducing the Dynamic Island cutout. The body size remains similar to the iPhone 17 Pro Max, but the screen‑to‑body ratio increases to approximately 92%.
| Model | Display Size | Screen‑to‑Body Ratio |
|---|---|---|
| iPhone 15 Pro Max | 6.7″ | ~89% |
| iPhone 16 Pro Max | 6.7″ | ~89% |
| iPhone 17 Pro Max | 6.7″ | ~90% |
| iPhone 18 Pro Max | 6.9″ | ~92% |
Refresh Rate – 120Hz ProMotion for Smoothness
The panel uses LTPO (Low‑Temperature Polycrystalline Oxide) OLED technology. This allows the refresh rate to dynamically scale from 1Hz to 120Hz. When scrolling or gaming, it runs at 120Hz for buttery smooth motion. When the screen is idle (e.g., showing the always‑on display), it drops to 1Hz to save battery.
Why this matters:
- 120Hz makes animations, scrolling, and gaming incredibly fluid.
- 1Hz enables an always‑on display without killing battery life.

Peak Brightness – 3,000 Nits for Outdoor Use
The screen will likely reach 3,000 nits peak brightness (HDR content) and around 2,000 nits typical outdoor brightness. This is a significant jump from the iPhone 17 Pro Max’s 2,200 nits peak.
Real‑world benefit: You can read the screen clearly even under direct sunlight. HDR videos will look more vibrant and impactful.
Always‑On Screen – Finally Feature‑Complete
Apple introduced always‑on display with the iPhone 14 Pro, but it was limited. The new model offers a more customizable always‑on experience. You will be able to show:
- Time, date, and notifications
- Live Activities (sports scores, timers)
- Widgets (weather, calendar)
- A dimmed version of your wallpaper
The 1Hz refresh rate and LTPO technology make this battery‑efficient.
Color Accuracy and HDR Support
The panel supports DCI‑P3 wide color gamut, 10‑bit color depth (1.07 billion colors), and Dolby Vision HDR. Apple calibrates each screen at the factory for outstanding color accuracy. Expect Delta E values below 1.0, which is reference‑grade for content creation.
Durability – Ceramic Shield 2.0
Apple will likely introduce Ceramic Shield 2.0, an even tougher glass formulation. Drop resistance should improve by 20–30% over the current generation. Scratch resistance also sees a modest boost.
