    Background: The Z30 uses PWM. After going below certain point it begins flickering the panel. Above a certain point you cannot see it. My 4S is DC all the way, no PWM.

    In a dark room with the brightness set to low, does the Passport's LCD screen exhibit PWM behaviours?

    I haven't seen any flickering yet with lowest settings in a complete dark environment.

    Bumping this. Normally you don't actually see the flicker with your bare eyes. Does anybody actually know if the Passport/Passport Silver backlight uses PWM?

    Uses PWM, confirmed by Blackberry Help on Twitter.
