What is the cause of those black bars on the picture? Their orientation changes by moving the camera.
The display is of a Samsung Galaxy S3 (i9300), an AMOLED display, set to minimum brightness, which involves PWM.
The camera is a Nikon 1 S2, picture taken at exposure of 1/16000 s. The PWM flicker should be in the range of 60Hz, so why the "fast" bars effect? Does the camera use a rolling shutter? EDIT: Yes it does, see my comment below
EDIT2: The phone display flickers with 300-400 Hz and low duty cycle (15% or less). See photos:
