Apple’s latest patent ensures your screen turns on to the right brightness

It’s that time of week again. Apple was awarded a new patent, related specifically to how devices like the iPhone handle a screen’s brightness — particularly in dark environments.

The patent is aimed at addressing the so-called “luminescence shock” that can occur when you turn your phone’s display on in the dark. Currently, when you turn the display on the phone can take a few seconds to adjust to an appropriate brightness. Using this patent, however, the device would “selectively limit its brightness level of a display device when the display device is activated in a dark environment.”

As you might expect, the tech would basically use the phone’s ambient light sensor when an event is triggered — like you receive a phone call or message. If that happens, instead of simply turning the display and adjusting the brightness after, the device would use the ambient light sensor to determine just how dark it is, then turn the display on at an appropriate brightness. There are embodiments of the tech without an ambient light sensor too. Instead of turning on the display at full brightness, the display could simply turn on at reduced brightness when a call or message has been received — which would still help avoid luminescence shock.

It’s important to note that this patent is a continuation of one that was filed back in 2016 — which is a continuation of a continuation of a continuation, etc. The original patent was filed in 2007 — so it’s clearly something that Apple has been working on for a while.

Of course, just because Apple has a patent for it, that doesn’t mean that the tech will ever show up in any Apple products. On top of that, if it does, that doesn’t mean that we will even know if it does. It may not show up as a setting — it could simply be a new feature in an iPhone that is not explicitly described.

The feature could also help saving power. If a phone is constantly turning on the display at full blast anytime a notification is received, it can have a pretty big effect on the battery. Turning it on at a lower brightness could help save on that battery.

It would be easy to see this patent being used in an iPhone, but also in the iPad, Apple Watch, and other devices — really anything with a screen could benefit from technology like this.

I was wrong about the iPhone 16
An iPhone 16 laying on a shelf with its screen on.

The iPhone 16 is a little over a month old, and I've been using it almost nonstop since it was announced last month. I reviewed the phone for Digital Trends and bought one with my own money as my personal phone of choice.

Not long after its unveiling, I wrote an op-ed complaining about the iPhone 16's lack of a 120Hz display. I said it was the "one thing holding back the iPhone 16" and that its 60Hz screen was "an unreasonable spec." I'd still like to see the refresh rate addressed with the iPhone 17, but after living with the iPhone 16 for over a month now, I've found that it's not nearly as big of an issue as I believed it would be.
A 60Hz screen matters, until it doesn't

The iPhone 17 Pro Max may slim down this particular feature

The iPhone's Dynamic Island is expected to get even smaller on the iPhone 17 series, according to technology analyst Jeff Pu (via MacRumors).

According to Pu, in a research note with investment bank Haitong International, the iPhone 17 Pro Max will offer a “metalens” for Face ID. Because of this, the Dynamic Island will be “much narrowed.”

If you aren’t already using the Apple Sports app, you need to
The Apple Sports app running on an iPhone 16.

Friends, we are well into the best time of the year: football season. The Lions are off to an incredible start, the Vikings look dangerously good, and I'm continually amazed by how bad the Browns are.

The 2024 season has been a lot of fun. Not only have the games been entertaining, but I've also had a much better time following the latest plays and scores on my phone. After begrudgingly using the ESPN app last year and the year before, I decided to go all-in on Apple Sports this year — and I couldn't be happier. If you have an iPhone and aren't already using Apple Sports, this is your reminder that you absolutely need to.
