With the upsurge of 3D movies in recent years and the development of 3D displays, 3D images that users could only watch in movie theaters can also be enjoyed at home.

At present, the control method of 3D glasses can refer to Taiwan Invention No. I366679 Patent, as shown in Figure 1, the first left image L1 that is only for the left eye is first transmitted through the communication medium 11, and then there will be a transmission Pause, that is, a vertical blanking interval of 12, and then, the first right image R1, which is only for the right eye, will be transmitted, and so on.

The right-eye shutter and left-eye shutter of the stereo glasses are independently controlled, which can be achieved by using the right-eye control signal 13 to control the right-eye shutter, and using the left-eye control signal 15 to control the left-eye shutter. The left-eye shutter and right-eye shutter of the stereo glasses can be controlled such that the left-eye shutter is in an open position for at least the first set of vertical blanking intervals 12, and the right-eye shutter is in an open position for at least the first set of vertical blanking intervals 12. Two sets of vertical blanking intervals 14, the first set of vertical blanking intervals 12 are alternated with the second set of vertical blanking intervals 14, and both occur during reception of right-eye content or left-eye content from a content source.

The right-eye shutter and the left-eye shutter of the stereo glasses can be controlled, so that the right-eye shutter and the left-eye shutter can be maintained at the closed position for a predetermined time 16 at the same time. As shown, the predetermined time 16 represents the time when the first left image L1 has been partially overwritten by the first right image R1. Therefore, in order to ensure that the right-eye shutter and the left-eye shutter of the stereo glasses are simultaneously maintained at the closed position within the predetermined time 16, the content of the right eye will be prevented from being seen by the left eye, and the content of the left eye will also be prevented from being seen by the right eye, The left-eye shutter is thus only in the open position for the duration of the first set of vertical blanking intervals 12 (ie when only left-eye content is displayed, etc.). In addition, the right-eye shutter is only in the open position during the duration of the second group of vertical blanking intervals 14 (that is, when only the content of the right eye is displayed, etc.), and this predetermined time 17 represents that the first right image R1 has been blocked by the second The left image L2 partially overwrites the full time frame, and so on.

Patent No. I366679 controls the right-eye shutter and left-eye shutter of the 3D glasses to switch between the closed position and the open position, and controls the right-eye shutter and the left-eye shutter of the 3D glasses to simultaneously maintain the closed position for a predetermined period of time 16, 17. However, in this control method, the right-eye shutter and the left-eye shutter have no visual sensitivity in the closed position and the predetermined time 16, 17, so when the right-eye shutter and the left-eye shutter switch between the closed position and the open position, relatively Causes a strong contrast of visual light and dark, so that the eyes are prone to visual fatigue. Therefore, how to solve the above-mentioned problems is an urgent research subject for those skilled in the art.
