Three-dimensional liquid crystal display device, and shutter glass and control method for the same

摘要

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 inverse of the fixed frequency, and opening sequence of the left and the right eye glass is consistent with the sequence of the left and right eye image signals.

主权项

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.
