The 3D bandwagon continues to gain momentum, if not followers, with the news LG plans to unveil the world’s first 3D smartphone at Mobile World Congress 2011 later this month in Barcelona. The LG Optimus 3D will pack a glasses-free LCD panel as well as a dual-lens camera for capturing 3D images and vides to help address the current lack of 3D content. It will also feature 3D-capable HDMI 1.4 and DLNA connectivity options for sharing 3D content.

As evidenced by Nintendo’s upcoming 3DS, mobile devices can offer glasses-free 3D as they only need to create a “sweet spot” for a single user, unlike larger display 3D TVs that rely on glasses to create the 3D effect for multiple users over a wide viewing area.

It will be interesting to see what specs the Optimus 3D will be sporting. All will be revealed at a special press event on February 14 at Mobile World Congress.
