Image flicker, which causes the blurring of a moving picture, is directly linked to frame rate frequency.

At 50Hz, the eye detects flicker, so motion blur is a problem. At 100Hz, the problem is greatly resolved, but Toshiba has gone even further with Clear Scan 200, which combines a 100Hz rate with scanning backlight technology to achieve the equivalent of a 200Hz effect.

The backlight control is split into three sections, and by synchronizing the control and video signals, motion blurring is virtually eliminated.
