iPhone 19e to Feature ProMotion Display, Apple’s Variable Refresh Rate Tech

Apple’s iPhone 19e, slated for release in early 2028, is rumored to incorporate a ProMotion display, bringing Apple’s variable refresh rate technology to its most affordable iPhone model for the first time. This upgrade signifies a potential shift for Apple, extending features previously reserved for premium devices to its entry-level lineup.

What is ProMotion?

ProMotion is Apple’s marketing term for displays with variable refresh rates. This technology dynamically adjusts the screen’s refresh rate based on the content being displayed, resulting in smoother scrolling, more responsive touch interactions, and improved power efficiency. GSM Arena reports that the iPhone 19e’s ProMotion display will be a variable refresh rate panel.

LTPO Technology: The Key to ProMotion

The implementation of ProMotion in the iPhone 19e is expected to be enabled by Low-Temperature Polycrystalline Oxide (LTPO) OLED display technology. MacRumors details that LTPO panels can dynamically adjust refresh rates between 1Hz and 120Hz. This technology is currently used in the iPhone 17 lineup and the iPhone Air.

The Evolution of LTPO Technology

Apple is reportedly developing a next-generation “LTPO+” display technology, incorporating oxide semiconductors in both switching and drive transistors. This advancement promises even better power efficiency. According to TechTimes, Apple plans to initially reserve LTPO+ for its higher-end models, including the iPhone Air and a potential foldable iPhone, freeing up standard LTPO panels for the iPhone 19e.

Timeline and Potential Delays

While the target launch for the iPhone 19e with ProMotion is early 2028, the rollout depends on the successful development and implementation of LTPO+ technology. Delays in the new technology could postpone the inclusion of LTPO panels in the iPhone 19e. The iPhone 17e currently uses a 60Hz LTPS TFT panel, and the iPhone 18e is expected to continue using the same technology.

ProMotion Refresh Rate Variations

It’s key to note that ProMotion displays vary in their capabilities. Earlier versions offered refresh rates ranging from 10Hz to 120Hz, while newer iterations can drop as low as 1Hz for maximum battery savings.

Key Takeaways
