LG is planning to launch the LG Optimus 3D at this year's Mobile World Congress in Barcelona on Monday February 14, 2011. Much like the Nintendo 3DS, the device won't require special glasses for 3D viewing.

In advance of the unveiling, a new teaser video for the device has leaked. It includes promotional text like "Finally, a smartphone that sees the world like we do" and "Entering a new dimension with LG Optimus." The teaser ends with the words, "No longer just an idea." Go ahead and get a glimpse of the 3D phone (it looks very similar to the LG Optimus 2X, courtesy of Pocket-lint:

LG hopes to overcome the lack of 3D content by creating its own ecosystem: the Optimus 3D will sport dual rear cameras (briefly shown in the teaser) to record 3D photos and videos, as well as HDMI 1.4 and DLNA support baked in to stream content to other 3D-capable devices. The South Korean electronics giant has yet to reveal pricing details or a release date for the Android-based device.
