Abstract:
The present invention relates to three-dimensional glasses, to a three-dimensional image display apparatus, and to a method for driving the three-dimensional glasses and the three-dimensional image display apparatus. The present invention is a method for driving three-dimensional glasses for watching a three-dimensional image consisting of a left-eye image and a right-eye image, wherein the method comprises the following steps: transmitting glasses characteristic information, including information relating to the opening/closing speed of shutters of a left-eye lens unit and a right-eye lens unit of the three-dimensional glasses, to an external three-dimensional image display apparatus for outputting the three-dimensional image; receiving synchronization information, including information relating to the output periods of the left-eye image and right-eye image, from the three-dimensional image display apparatus; and synchronizing, using the synchronization information, the opening/closing periods of the shutters of the left-eye lens unit and the right-eye lens unit with the output periods of the left-eye image and right-eye image outputted by the three-dimensional image display apparatus. The synchronization information includes information on the time of opening the shutter of the left-eye lens unit, information on the time of closing the shutter of the left-eye lens unit, and information on modes for indicating the type of image outputted by the three-dimensional image display apparatus, and the method for driving the three-dimensional glasses and three-dimensional image display apparatus of the present invention, efficient data communication between the three-dimensional glasses and the three-dimensional image display apparatus is enabled, in order to increase the convenience of a user watching the three-dimensional images and prevent the unnecessary consumption of a battery of the three-dimensional glasses.
