Designed to take on Apple's iPad, LG's new tablet runs Android Honeycomb and has an Nvidia Tegra 2 1GHz dual-core processor.
The LG Optimus 3D smartphone has a 4.3-inch glasses free 3D screen and a dual lens camera for capturing photos and video in 3D.
LG used an applied parallax barrier technology to create the glasses-free 3D effect on the screen. The technology puts a series of slits on the front of the LCD screen that block light in a way that ensures a user's left and right eye see different images, thereby creating the illusion of depth for the 3D image.
The Optimus 3D is based on a 1GHz OMAP4 dual-core processor from Texas Instruments. It has an HDMI (High Definition Multimedia Interface) connector and supports the DLNA (Digital Living Network Alliance) networking standard that enables simpler transfer of pictures and video between devices.
LG did not say what kind of OS the phone uses, and could not immediately be reached for comment. UK network operator Three has already confirmed that it will offer the phone but has not released information about pricing or plans yet.
The South Korean electronics giant also plans to show off two additional smartphones at the Mobile World Congress, the Optimus 2X and Optimus Black, details of which have previously been announced. The Optimus 2X has a dual-core Nvidia Tegra 2 processor on board for powerful multimedia, including smooth web browsing and 1080p HD video playback, LG said. The Optimus Black is a thin, light Android smartphone with a 4-inch display designed to be read under any lighting situations.
LG said 2 million pre-orders have already been placed for the Optimus Black since it was unveiled at the International Consumer Electronics Show in Las Vegas in January.
LG's mobile phone operations struggled last year due to a focus on emerging markets. The company caught onto the rise of smartphones late compared to rivals, but has worked hard to make a comeback.
The Mobile World Congress opens on Monday in Barcelona.
