LG details Optimus Pad, smartphone with 3D screen

LG put a 3D camera on its iPad-rival and a glasses-free 3D screen on its latest smartphone

LG Electronics provided details on some of its most highly anticipated mobile gadgets on Sunday, including the LG Optimus Pad tablet and Optimus 3D smartphone, which will be shown at the Mobile World Congress in Barcelona this week.

The Optimus Pad comes with an 8.9-inch touchscreen and a built-in 3D camera, according to an LG statement. Designed to take on Apple's iPad, LG's new tablet has the latest version of Google's Android mobile OS on board, Honeycomb, and an Nvidia Tegra 2 1GHz dual-core processor.

The device's screen has a resolution of 1280 by 768. Images and video taken with the 3D camera can be viewed on 3D TVs or shared on the Web via YouTube 3D, LG said.

The LG Optimus 3D smartphone, with a 4.3-inch glasses-free 3D screen, features a dual-lens camera for taking pictures and video in 3D, the company said.

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.

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.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
