Abstract
The present invention relates to a three-dimensional liquid crystal display device, and shutter glasses and a control method for the shutter glasses. In the case, the three-dimensional liquid crystal display device comprises: a backlight controller, for controlling turn-on of a backlight, and keeping the backlight normally on while left and right eye images are alternately output by the panel; and a transmitting module, for outputting a picture refresh signal with a fixed frequency, and outputting a backlight enabling signal when the backlight are turned on. The shutter glasses include a controller. Under the function of the controller, the shutter glasses receive the picture refresh signal with a fixed frequency and the backlight enabling signal, and 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. When counted time reaches a set time count, the shutter glasses control a left eye glass or a right eye glass to open for a set open time Topen in a continuous manner, wherein a sum of the time count and the open time is shorter than inv…
