11. In LCD, the refresh rate of the screen is a) 60 frames/sec b) 80 frames/sec c) 30 frames/sec d) 100 frames/sec
They don't actually go dark between frames, and as a result, that 60hz flicker doesn't exist. Because of this, LCDs are made at 60Hz refresh rate, as that is plenty high for smooth, fluid motion, and without the darkening between frames, they do not need the high speed to eliminate flicker.
