1. A method for controlling three dimensional displays, comprising:

  • acquiring a current time when a liquid crystal raster device is driven to shield light by an alternating current 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 alternating current driving voltage signal, wherein the setting period of time refers to a period of time during which a polarity of the alternating current driving voltage signal changes from positive polarity to negative polarity or from negative polarity to positive polarity such that an image crosstalk is generated when the backlight source is in a normal-open state, wherein the transmittance of the liquid crystal raster device when the alternating current driving voltage signal maintains its polarity is lower than the transmittance of the liquid crystal raster device when the polarity of the alternating current driving voltage signal changes from positive polarity to negative polarity or from negative polarity to positive polarity,wherein the image crosstalk occurs as a left eye of a viewer views lights emitted from a right eye sub-pixel and a right eye of the viewer views lights emitted from a left eye sub-pixel as the transmittance of the liquid crystal raster device rises when the polarity of the alternating current driving voltage signal changes from positive polarity to negative polarity or from negative polarity to positive polarity.
