Under 3D display technology, if the user is on the call, then the screen can show the person, so that they are talking
Samsung has filed a new patent application for 3D displays in the US Patent and Trademark Office, which users can connect to their smartphones and tablets. These displays can be installed in a TV set or monitor and can be viewed from photos and videos to 3D games. Photographs submitted with this patent reveal that users can forward the information presented on the smartphone to the 3D screen.
Android reported on Friday, “For example, if the user is on the call, the screen can show the person that they are having a conversation and use the display to control the playback of music files. It can also be done, which the users have forwarded from their handsets. “
