Photos: LG Optimus 3D glasses-free smartphone

The handset has a 4.3-inch WVGA autostereoscopic 3D touchscreen - so the device does not require the user to wear glasses to view the 3D.

The LG Optimus 3D also offers 3D video recording - hence the dual cameras on the back, pictured above.

The twin five-megapixel cameras are positioned 24mm apart to record at slightly different angles for the 3D effect.

LG also took the wraps off a tablet - the LG Optimus Pad, shown above, runs Google's Android 3.0, aka Honeycomb. It is powered by a 1GHz Nvidia Tegra 2 dual-core processor.

Like the LG Optimus 3D smartphone, the Optimus Pad packs dual five-megapixel cameras for 3D video recording - but the Pad does not have a 3D screen, so while 3D films can be made on the device, the 3D effect cannot be viewed on the Pad.

The Optimus Pad has an 8.9-inch screen, weighs 630g and measures 243mm x 149mm x 13mm.
