The iPhone 17 lineup, expected to launch in September 2025, is poised to introduce several significant display enhancements that mark a notable evolution from the iPhone 16 series. These upgrades focus on screen size, refresh rates, brightness, and new technologies aimed at improving user experience and device performance.
Larger and Varied Display Sizes
One of the most prominent changes is the increase in display sizes across the lineup. The base iPhone 17 model is rumored to feature a 6.3-inch display, up from the 6.1-inch screen on the iPhone 16 base model. The iPhone 17 Air is expected to have a 6.6-inch display, while the Pro and Pro Max (rebranded as Ultra) models will sport 6.3-inch and 6.9-inch screens respectively. This expansion caters to users seeking larger viewing areas without drastically altering the device’s overall design language[1][2].
ProMotion Technology Across All Models
Historically, Apple’s ProMotion 120Hz refresh rate technology was exclusive to the Pro models. However, the iPhone 17 series is expected to democratize this feature, bringing ProMotion to the entire lineup, including the base and Air models. This means all iPhone 17 devices will support refresh rates up to 120Hz, enabling smoother scrolling, more fluid animations, and enhanced gaming and video playback experiences.
Unlike the previous generation where non-Pro models were limited to 60Hz, the iPhone 17 base and Air models will likely have fixed 120Hz displays rather than adaptive refresh rates, which may not be branded as “ProMotion” but will still deliver a substantial visual upgrade. The Pro models will continue to benefit from LTPO OLED panels that allow variable refresh rates from 1Hz to 120Hz, optimizing power efficiency and enabling features like always-on display[1][2].
Brighter and More Durable OLED Panels
The iPhone 17 and iPhone 17 Air are expected to utilize OLED panels sourced from Samsung, specifically the M14 panel, which offers a 30% increase in brightness and improved longevity compared to the previous generation. This enhancement will make the displays more vibrant and easier to view in bright environments.
Apple had planned to introduce a new scratch-resistant and anti-reflective coating on the Pro models’ displays to improve durability and reduce glare. However, due to manufacturing scale-up challenges, this coating rollout has been delayed or possibly canceled for this year, meaning the iPhone 17 may retain the current Ceramic Shield glass without the new coating[2].
Always-On Display Potential
With the adoption of ProMotion and LTPO technology across all models, Apple may extend the always-on display feature beyond the Pro models to the entire iPhone 17 lineup. This would allow users to see essential information such as battery status, widgets, and notifications even when the screen appears off, enhancing convenience without significantly impacting battery life.
While this feature is anticipated, it remains uncertain if Apple will enable always-on display on non-Pro models at launch or reserve it as a Pro-exclusive feature[2].
Additional Display-Related Enhancements
- The base iPhone 17 is rumored to have a 24-megapixel front camera, doubling the resolution from the iPhone 16, which complements the display improvements for better selfie and video call quality[1].
- Vapor chamber cooling technology may be introduced in the Pro models to manage heat more effectively, indirectly benefiting display performance by preventing thermal throttling during intensive usage[2].
Summary
The iPhone 17 series is set to bring meaningful display upgrades, including:
- Larger displays across all models, with the base model increasing to 6.3 inches.
- ProMotion 120Hz refresh rates extended to the entire lineup, enhancing smoothness and responsiveness.
- Brighter and more durable OLED panels, improving visibility and longevity.
- Potential always-on display functionality for more models.
- Enhanced front camera resolution supporting better display usage.
These features collectively suggest that Apple is focusing on refining the visual experience and performance consistency of the iPhone 17, making it a compelling upgrade for users seeking improved display technology[1][2].
