It means that NBC has tested various different smartphone models of various manufacturers. All those tested models are 100%. Of those, 53% of the models have been PWM-free.

Tyically, NBC tests only one device per model, so NBC cannot detect frequencies within one model series, of which some might have different display panels, such as IPS or OLED, or different IPS panels from different panel manufacturers, and possibly some IPS panel with PWM or some other IPS panel without PWM.

Hence, to avoid PWM, do not buy a smartphone model with tested PWM. If PWM occurs in all smartphone models of a manufacturer, choose a different manufacturer.

Apple's move towards OLED means that more and more iPhones are likely to have PWM. For IPS, there are models (or series of display panels) with or without PWM, but rarely a guarantee that a particular display panel series is used.

Hello, I am a flicker-sensitive user.
My most commonly used devices are the iPad mini 6 and iPhone 11. After reading your detailed review, I really appreciate your effort, as it cleared up many of my doubts regarding the screen.
By the way, I would like to ask for some clarification on something you mentioned in the review: that no PWM was detected, and that PWM wasn't detected in 53% of devices. Does this mean that 47% of iPad Air 6 devices use PWM dimming?
I recently upgraded to the iPad Air 6 and have been experiencing slight headaches while using it, something I didn't have with the iPad mini 6.
I'm wondering if I may have received one of the iPad Air 6 units that use PWM dimming?
Thank you very much!

The review says, "The iPad Air 11 (2024)'s Liquid Retina IPS display is likely the same panel as in its predecessor and the model before it—at least that's what our measurements suggest." The iPad Air 5th gen had temporal dithering, so I'd expect this 11 inch one to have it too.

The 13 inch Air may be using a new panel, so I'm hoping that one at least gets tested for temporal dithering.

Same here. The reason that I keep refreshing notebookcheck.net and the Youtube Channel Additional Contents is the Temporal Dithering and PWM. I really like the Apple Environment but I need to spend most of my time with computers/tablets. Returned my M4 iPad Pro for eye strain (PWM) after using 4+ hours, but I need to use it for 10-14 hours for text reading/document editing every day, the eye-unfriendly hardware really hurts.
