Every iPhone 17 model expected to get always-on display tech

AppleInsider

Apple will bring LTPO always-on display technology to its entire iPhone line with the iPhone 17, an analyst claims.

Variable refresh rates enable features like an always-on display or ProMotion, and Apple has reserved those features for the pro iPhone models so far. Analyst posts on Tuesday now indicate that there could be a change on the horizon.

According to David Naranjo of Display Supply Chain Consultants, "LTPO penetration [in smartphones] rose from 10% in 2021 to 23% in 2022."

"The rise in LTPO is a result of strong demand for higher refresh rates and always on displays at lower power," he continued. "Apple adopted its first LTPO smartphones in 2021 on the iPhone 13 Pro and Pro Max... In 2025, DSCC expects all Apple's iPhone 17 models to adopt LTPO panels as LTPO capacity continues to rise and costs fall."

What is LTPO?

Low-temperature polycrystalline oxide (LTPO) is a backplane technology that enables a display to dramatically and dynamically change its refresh rate. It also does so without requiring any extra hardware components between the graphics controller and the GPU.

The lack of extra hardware means there are fewer components powering the display, reducing the energy requirements and extending the battery life for the hardware.

The tech is used to enable Apple's ProMotion display system, which can move from a refresh rate as low as 10Hz to a high of 120Hz when operating, or 1Hz for the always-on display on iPhone 14 Pro. It is also what makes the Apple Watch capable of refresh rates as low as 1Hz on the Apple Watch Series 5 and later.

A low refresh rate can be used when nothing changes on the display, minimizing power usage. Whereas for drawing with a stylus or for games, a 120Hz refresh rate could be more beneficial to users.

LTPO technology was introduced to iPhone to enable the ProMotion feature in iPhone 13 Pro, and then later, it enabled the lower refresh rate needed for the always-on display. Bringing LTPO to non-pro iPhones doesn't guarantee ProMotion is coming to those devices, but it does mean Apple is likely to include the always-on display feature across all models.

Apple has, so far, reserved ProMotion for pro devices like the iPad Pro, MacBook Pro, and iPhone Pro. It doesn't seem likely that ProMotion will make its way to cheaper devices.

There are other uses for LTPO beyond the always-on display, too. For example, users viewing video shot at 24Hz will be able to enjoy that content in its native frame rate.

The iPhone 17 range is due in 2025.

The Display Supply Chain Consultants, headed by Ross Young, has an extremely solid reputation for not just extracting data from Apple's supply chain, but also discerning what the company's plans and timetables are.

2025. Can we just wait a bit? There’s no fun in tech any more as we know everything 6 months and up before the release!

My brother in Apple, you're literally commenting on an apple insider article on a website called AppleInsider. That's like going to the New York Times and complaining about all the bad news.

I really don't care or like always on display. I have iPhone with feature called "Raise to Wake" and it works well when I need to interact with screen. Why I want to have a screen on when sitting in pocket/purse or away from it ?

The one recurring theme with most new iPhone features like always-on-display and dynamic island is that regardless of all the hoopla around the initial announcement they all quickly fade into the background and go largely unnoticed. This normalization cycle gets shorter with each additional feature. 

The always-on-display works well. No complaints at all in terms of battery drain, at least with the Pro Max. Dynamic island, okay I guess but I don’t really notice it to be anything that stands out at all. I’d be hard pressed to describe what it does that’s radically different than before it arrived. 

This isn’t a negative commentary, it’s simply an admission that the iPhone has reached a level of maturity and refinement that there’s not a whole lot of new things they can add to what is already a spectacular formula that will leave you in awe for more than a few moments. 

It’s probably time for Apple to focus on fundamental changes like significantly improved battery life and significantly reduced weight. Adding all the bells and whistles is fine, but the steadily increasing bulk and weight tells me that it’s time to solve one or two very difficult challenges before slapping on another layer of new features whose half-life of excitement is now measured in days, maybe even hours.

I personally have no use for such a thing, so as long as I can turn the feature off, I'll be fine.

Raise to wake meets my needs as well just another way for Apple to shake down our pockets.

I would actively dislike it.  Unnecessary battery drain (however slight) unwanted brightness in dark environments, etc.  But as you say, as long as I can turn it off...
