Method, apparatus, and system for controlling three dimensional displays are provided. The method comprises: acquiring a current time when a liquid crystal raster device is driven by a AC driving voltage signal; shutting down a backlight source when the current time is within a setting period of time included in an input period of the AC driving voltage signal, wherein the setting period of time refers to a period during which a polarity of the AC driving voltage signal changes such that an image crosstalk is generated when the backlight source is in a normal-open state. Since the backlight source is shut down and stops providing backlight to the panel when the current time is within the setting period, the panel displays black thereby left eye and right eye images are prevented from entering into error regions of view, the image crosstalk is reduced and a display quality is improved.
