Apple’s upcoming standard iPhone 15 models will lack an LPTO display, meaning the handsets will once again lack ProMotion support and the always-on display option available on the iPhone Pro models.
That news comes from an industry source cited by news aggregator account “yeux1122” on the Korean Naver blog. If the post is correct, only Pro models in the iPhone 15 series will boast the LPTO panels required for ProMotion.
From the machine-translated blog post (via MacRumors):
Apple is said to have already made arrangements to deliver iPhone 15 series display panels to domestic companies, and will soon finalize details and prepare for mass production. What is confirmed here is that only the Pro Series will have a specification that supports LTPO 120 refresh rate, with the basic regular Plus model not having it in its requirements.
The current iPhone 14 Pro and iPhone 14 Pro Max models are equipped with updated low-power display backlighting that supports ProMotion refresh rates that range from 1Hz to 120Hz. The display adapts to the type of content being consumed, using lower refresh rates for static content, and higher refresh rates being used for activities like gaming or viewing video.
In September 2022, well-connected display analyst Ross Young said Apple plans to extend its new Dynamic Island feature to all four iPhone models next fall. The feature is currently exclusive to the iPhone 14 Pro and iPhone 14 Pro Max models.
In a tweet, Young said he expects the Dynamic Island to be available on the standard iPhone 15 models next year. However, he still does not expect apple to expand the use of the standard LTPO display to all iPhone 15 models. This indicates that the devices will once again lack ProMotion support and an always-on display option like Pro models have.
