[0029] figure 2 is a schematic block diagram of stereo glasses 200 according to an embodiment of the present invention. Such as figure 2 As shown, the stereo glasses 200 according to the present invention includes a signal receiving unit 210 , a central control unit 220 and left and right LCD lenses 230 , wherein the central control unit 220 also includes a synchronization control unit 240 and a power control unit 250 .

[0030] The signal receiving unit 210 is used for receiving synchronization signals. Specifically, the signal receiving unit 210 may include an infrared receiver (IR RCV) 212 for receiving a synchronous signal, such as a modulated synchronous signal transmitted by a TV terminal; and a signal demodulator 214 for synchronizing the received The modulated synchronous signal is demodulated to obtain the demodulated synchronous signal. In addition, the signal receiving unit 210 may further include an FM receiver 216 for synchronously receiving audio signals of ...

[0055] Figure 4 is a schematic block diagram of the structure of the second embodiment of the present invention. Such as Figure 4 As shown, different from the first embodiment, the stereo glasses 200 also include a channel recording and prediction unit 280, configured to record the current synchronous signal and / or audio signal after the synchronous signal and / or audio signal is detected. channel, so that when adjusting the channel or re-scanning the channel after the signal changes, it can automatically predict possible effective and high-quality channels according to the currently recorded channel information, and perform small-scale channel adjustment or scanning.

[0056] If the 3D synchronization signal is interrupted for some reason during the working process, the channel record and prediction unit 280 automatically predicts the 3D synchronization time according to the previous control record. Similarly, if the synchronous signal of the TV accompanying audio channel ...

Abstract

The invention provides a pair of three-dimensional glasses and a control method thereof. The three-dimensional glasses comprise a signal receiving unit used for receiving synchronization signals, left and right LCD (Liquid Crystal Display) lenses used for observing three-dimensional images and a central control unit used for controlling the signal receiving unit and the left and the right LCD lenses according to the synchronization signals received by the signal receiving unit; the central control unit comprises a synchronization control unit and a power control unit, wherein the synchronization control unit is used for controlling the left and the right LCD lenses to open and close alternately according to the synchronization signals received by the signal receiving unit, the power control unit is used for monitoring the synchronization signals and dynamically controlling the power supply of a part of units and / or all units of the three-dimensional glasses according to monitoring results, and when no synchronization signal is monitored in a period of time longer than a preset threshold value, the power control unit stops supplying power for a part of units and / or all units of the three-dimensional glasses. The invention can better realize the synchronism and the low-power consumption control of the three-dimensional glasses.

Description

technical field [0001] The invention relates to the technical field of video display, in particular to a kind of stereo glasses and a control method thereof. Background technique [0002] When people's eyes watch the three-dimensional scene, usually the left eye can only see the scene of the left eye, and the right eye can only see the scene of the right eye. However, due to the distance between the left and right eyes, there is a slight difference between the viewing angles of the two eyes, and this difference can cause a slight displacement between the scenes seen by the two eyes. When the images viewed by both eyes are transmitted to the human brain, the human brain will skillfully fuse the images of the two eyes, thereby producing a stereoscopic visual effect with a sense of space in the human brain. Therefore, the human eye can see a three-dimensional scene. [0003] However, when viewing a scene on a computer screen, the scene on the computer screen is a planar image...
