Do all/most e-readers use PWM? I was looking into the Kobo Libra and apparently it doesn't have the PWM flickering issue that the Kobo Forma has. I've tried out the Forma when it was released and from what I understand, the flickering issue was only from adjusting the brightness. Regardless, it doesn't bother me, but I am curious if the Kobo Libra uses PWM and just doesn't have the flickering issue or if it doesn't use PWM outright.

I have learned that PWM causes fatigue even if it's unoticeable to the naked eye (your brain still processes it). I would like to consider non-PWM options only to reduce fatigue. I work with computers 10-16 hours a day and am most likely suffering from fatigue from PWM monitors and would like to reduce my interactions with PWM displays as much as possible.
