Abstract

The invention relates to a pair of 3D glasses (three dimensional)comprises a signal receiver, a programmable storage, a shutter and a processing unit, wherein the signal receiver is suitable for receiving a wireless signal, demodulating the wireless signal into a synchronous signal and password, and then outputting the synchronous signal and password; a preset password is stored in the programmable storage; and the processing unit is used for receiving the password and the synchronous signal, reading the preset password, and comparing the password with the preset password so as to control the shutter, and receive and display an image signal according to the synchronous signal when the password is consistent with the preset password.

Description

technical field [0001] The present invention relates to a kind of 3D glasses, and particularly relates to a kind of 3D glasses and its operating method for making the 3D glasses display 3D images when the password in the signal sent by the display device end matches the preset password of the 3D glasses. Background technique [0002] With the development of 3D technology, more and more images of movies or amusement parks are produced with 3D technology. When the viewer enters a movie theater or an amusement park, he needs to use 3D stereoscopic glasses to watch 3D images. However, since the 3D glasses in movie theaters or amusement parks cannot be fixed, the loss rate is quite high. In order to avoid increasing related costs, movie theaters or amusement parks will charge users a deposit for 3D glasses. However, this method is suitable for low-priced 3D glasses. If it is high-priced 3D glasses, the user may not purchase the 3D glasses because the deposit is too expensive. ...
