The method of imagery.

The current 3D display mainly cooperates with the shutter switch status of the 3D glasses worn by the user to achieve the time-sharing 2D image of the left eye and the 2D image of the right eye to the user's vision, and form a 3D stereoscopic vision for the user. (Equivalent to the formation of 3D images), such 3D glasses mainly include Active shutter 3D glasses and Passive Polarizer 3D glasses. However, not all users are accustomed to watching 3D images for a long time. This is because the 3D images need to consume a lot of dynamic vision of 3D glasses users, which is more likely to cause user fatigue. Therefore, users also have The need to watch 3D images and change to 2D images. However, when the user removes the 3D glasses, viewing the 3D display will only result in extremely blurred images, and it is completely unable to meet the demand for watching the program, and the user wants to separately watch the TV program played by the 3D display in 2D images. It is also extremely inconvenient.

In order to solve the problem that the 3D display can no longer provide the 2D image to meet the user's needs when the 3D image is provided in the 3D display in the prior art, the present invention provides a method for simultaneously broadcasting a plurality of 2D images to a plurality of users by using a 3D display. In order to enable a plurality of users wearing 3D glasses to freely choose to view 2D images or 3D images.
