LG to show glasses-free 3D smartphone at MWC

The smartphone will come with a dual-lens camera for 3D recording

LG Electronics plans to unveil the Optimus 3D, a smartphone that will allow consumers to record and view 3D images and videos without glasses, at Mobile World Congress (MWC), the company said on Tuesday.

The phone, which LG calls its most advanced to date, will come with a dual-lens camera for 3D recording and an LCD panel for glasses-free 3D viewing. Phone owners will be able to let others view the content using HDMI or DLNA to connect to an external screen or other device, LG said in a brief statement.

The company didn't provide other technical details, such as the size of the screen. However, at CES in January, the company introduced a new 4.3-inch glasses-free 3D screen for mobile devices. The display has a resolution of 480 by 800 pixels and is intended for use in smartphones designed for movie viewing and gaming, the company said at the time.

LG's 3D display uses an applied parallax barrier technology, which delivers "a series of light-blocking slits attached to the front of the LCD panel", according to LG. They ensure that the left and right eyes see different images, creating the illusion of depth.

LG is stepping up its assault on the smartphone market by trying to be at the cutting edge of new hardware technology. In December, the company unveiled the Optimus 2X, a smartphone running Android on Nvidia's dual-core Tegra2 processor capable of 1080p HD video playback and recording.

3D is expected to be one of the smartphone trends at this year's Mobile World Congress. Other expected trends include dual-core processors, NFC (Near-Field Communications) and faster mobile Internet connections. Screens are also growing larger and the phones thinner.

Mobile World Congress takes place in Barcelona and opens on Feb. 14.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
