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.
