New details emerge about Apple's iPhone 18 lineup displays, including size adjustments and a shift toward under-display Face ID technology.
New specifications for Apple's upcoming iPhone 18 series have surfaced via reliable tipster Digital Chat Station, revealing significant display changes across all four expected models. The leak provides concrete details about screen sizes, refresh rates, and biometric authentication design as Apple continues refining its 2026 flagship lineup.
The standard iPhone 18 will reportedly feature a 6.27-inch LTPO display with 120Hz refresh rate, maintaining the Dynamic Island design introduced in previous models. LTPO (Low-Temperature Polycrystalline Oxide) technology enables more efficient power management by dynamically adjusting refresh rates between 1Hz and 120Hz based on content, extending battery life during static screen viewing.
Notably, the iPhone 18 Pro model will share the same 6.27-inch LTPO 120Hz panel but implement a significant design shift: an under-display cutout for Face ID sensors. This advancement follows years of development in miniaturizing infrared cameras and dot projectors beneath the display surface, potentially eliminating the need for visible cutouts while maintaining facial recognition security.
The Pro Max variant will scale up to a 6.86-inch LTPO display with matching 120Hz capabilities and the same under-display Face ID implementation. This represents a noticeable increase from the iPhone 15 Pro Max's 6.7-inch screen, suggesting Apple may reduce bezel sizes to accommodate larger panels without dramatically increasing device dimensions.
Meanwhile, the iPhone Air 2 (positioned as a successor to the rumored iPhone Air) will sport a 6.55-inch LTPO 120Hz display but retain the traditional Dynamic Island design. This differentiation creates clearer segmentation between Apple's premium and mid-tier models, potentially allowing cost savings on the Air lineup while reserving the latest biometric innovations for Pro devices.
Industry sources indicate the iPhone 18 series is currently in sample production, aligning with Apple's typical development timeline for September launches. These display changes coincide with separate reports about upgraded front-facing cameras across all iPhone 18 models, suggesting comprehensive imaging improvements beyond screen technology.
The move toward under-display Face ID represents Apple's continued ecosystem strategy, enhancing hardware integration while maintaining security standards unique to iOS devices. As Android manufacturers increasingly adopt under-display cameras, Apple's implementation focuses specifically on biometric sensors rather than the selfie camera, preserving the company's emphasis on secure authentication.
Display analyst Ross Young notes: "Consistent 120Hz adoption across all models addresses longstanding consumer demand for smoother scrolling and responsiveness. The size adjustments indicate Apple is optimizing viewable area while maintaining comfortable device handling—a critical balance in premium smartphones."
These specifications remain unconfirmed by Apple but align with the company's pattern of incremental display advancements. The iPhone 18 series is expected to debut in fall 2026, potentially across two separate events as Apple reworks its launch strategy.
For reference, Apple's current display technologies are detailed in their iPhone technical specifications documentation.
