Apple will introduce a pulse width modulation toggle within iOS 26 accessibility settings for iPhone 17 Pro users. The company addresses screen flickering concerns through this new Display and Text Size option. MacRumors discovered this feature that targets OLED display dimming methods.
Pulse width modulation rapidly switches pixels to control screen brightness levels. Sensitive individuals experience headaches, eye strain, and dizziness from this flickering effect. These symptoms appear most frequently at reduced brightness settings.
The toggle provides alternative dimming technology without flickering characteristics. Apple warns that disabling pulse width modulation may compromise display performance during low-brightness scenarios. This marks the first occasion Apple acknowledges pulse width modulation as a legitimate user concern.
Previously, affected users avoided OLED iPhone models or endured the uncomfortable symptoms. Apple responds to customer feedback with this accessibility enhancement. The feature currently applies to iPhone 17 Pro models, though expansion to base iPhone 17 and iPhone Air variants remains possible.
