Claim Text:
1. Shutter glasses including a controller, wherein the controller comprises: a receiving module, for receiving a picture refresh signal with a fixed frequency and a backlight enabling signal, which both are emitted by a three-dimensional liquid crystal display device, wherein the picture refresh signal alternately corresponds to a left eye image signal and a right eye image signal based on the fixed frequency thereof; a timing module, which is coupled to the receiving module can start timing once the picture refresh signal triggered by a positive source is detected, with the time point when the backlight enabling signal is received by the receiving module as a starting point; and an enabling module, coupled to the timing module, for outputting, when time counted by the timing module reaches a set time count, a control signal to open a left eye glass or a right eye glass for a set open time in a continuous manner, wherein a sum of the counted time and the open time is shorter than the inverse of the fixed frequency, and opening sequence of the left and right eye glasses is consistent with sequence of the left and right eye image signals.
