Managing PWM on OLED iPhone & iPad Displays
Some iPhone and iPad users are sensitive to PWM flickering on the latest devices OLED displays. PWM, which stands for Pulse Width Modulation, can cause some users to have eye strain, feel nauseous or dizzy, or have headaches from the screen flickering when using an OLED screen device with PWM.
All new model iPhone and iPad devices with OLED displays have PWM, including the iPhone 15, iPhone 15 Pro, iPhone 15 Plus, iPhone 15 Pro Max, iPhone 14, iPhone 14 Pro, iPhone 14 Pro Max, 13, iPhone 13 Pro, iPhone 13 Pro Max, iPhone 13 mini, iPhone 12, iPhone 12 Pro, iPhone 12 Pro Max, iPhone 12 mini, iPhone 11 Pro, iPhone 11 Pro Max, iPhone XS Max, iPhone XS, iPhone X, and iPad Pro 12.9″ M1. The remaining iPhone models that use LCD displays do not have this issue (at least to an extent that bothers users anyway), which includes the iPhone 11, iPhone SE iPhone XR, iPhone 8 Plus, and iPhone 8 and older.
While the majority of people do not have any issues with OLED PWM, if you are bothered by OLED PWM, it’s fairly obvious because you feel discomfort almost immediately when looking at an OLED display. Assuming you fall into that unfortunate latter category, this workaround may help.
