Apple has just changed the game for display technology with its iPhone 17 lineup, giving users the power to completely turn off PWM dimming for the very first time. This update isn’t just another technical tweak—it’s a massive win for users who have struggled with eye strain, headaches, and discomfort caused by screen flicker.
Why Apple’s Move to End PWM Dimming Matters
For years, Apple’s stunning OLED screens came with one drawback: PWM dimming (Pulse Width Modulation). While it helped manage brightness, many sensitive users reported eye fatigue, dizziness, and migraines. By letting users disable PWM dimming, Apple is addressing one of the biggest pain points in modern smartphone displays.
What Is PWM Dimming and Why It Bothers Users?
PWM dimming works by rapidly flickering the screen at different rates to control brightness. Most people don’t notice it—but those sensitive to flicker can experience serious discomfort.
- Low brightness = higher flicker risk
- Long screen use = stronger strain symptoms
By offering a toggle to disable PWM entirely, iPhone 17 ensures consistent, stable lighting—a change that could redefine how people use their phones for hours without discomfort.
iPhone 17 Display Settings: A Health-Friendly Upgrade
Inside the new Display & Brightness settings, users can now find a “Disable PWM Dimming” option. Once enabled, the phone controls brightness through DC dimming or alternative methods that eliminate flicker.
This means:
- Smooth visuals without hidden flicker
- Comfortable use at any brightness level
- A healthier screen experience for everyone
How to Turn Off PWM Dimming on iPhone 17
Apple has kept it simple:
- Go to Settings
- Tap on Display & Brightness
- Find the toggle: “Turn Off PWM Dimming”
- Enable it—and enjoy a flicker-free screen
Impact on Eye Health and User Comfort
For users with light sensitivity or migraine conditions, this is a game-changer. Turning off PWM dimming can lead to:
- Reduced headaches
- Less strain during long usage
- Better sleep patterns from less visual stress
Apple’s Commitment to Accessibility and User Choice
This new feature is more than a technical update—it’s a statement. Apple is showing that user health and accessibility matter just as much as design and performance. For the first time, choice is in the hands of the user.
Reactions from the Tech Community
Early testers and display experts have praised the move, calling it “the biggest usability improvement since OLED adoption.” Social media discussions highlight excitement from users who previously avoided OLED iPhones because of PWM issues.
Will Other Smartphone Brands Follow Apple’s Lead?
Apple may have set a new standard for the smartphone industry. If competitors want to keep up, Samsung, OnePlus, and Google may need to offer similar anti-PWM features. The pressure is on.
Final Thoughts on iPhone 17’s PWM-Free Future
The iPhone 17’s ability to fully turn off PWM dimming is more than a feature—it’s a health-focused revolution. By listening to its users and addressing a real-world issue, Apple has taken a major step toward making smartphones more comfortable and inclusive.
The flicker-free future has finally arrived, and it starts with the iPhone 17.
