According to here the Librem 5 LCD backlight is configured to use PWM at 200Hz. Now 200Hz is low enough to cause eyestrain, headaches and other neurological problems in people with damaged eyes/nervous systems (such as myself).
I’m wondering:
a) Why was 200Hz chosen?
b) Do you know if there are any negative effects from raising the PWM frequency to avoid eyestrain?
Keep up the good work
