Is related to the screen refresh, take pictures, sometimes luck, you can take a full picture, most of the time there will be black bar, this is perfectly normal
This is really a normal phenomenon...Refresh rate 60HZ, which means that it refreshes 60 times per second...If your camera's exposure time is not good, you will feel the flash of the picture being taken...As far as you say, notebooks do not, this may be related to brightness settings, and is not the kind of film and so on
The LED screen is progressive, not always bright.Eyes see, scan more than 25 screens per second can not feel flashing, camera take pictures much faster, generally 1/125 seconds shutter speed, of course, will be photographed flashing.A liquid crystal display (LCD) is a flat, ultra thin display device consisting of a certain number of color or black and white pixels, placed in front of the light source or reflector.
