Sales of LG Electronics’ Cinema 3D TV began today in the domestic market of South Korea – a telling lead-up to the device’s global release next month.

The LG Cinema 3D TV works by using LG’s Film Patterned Retarder (FPR) technology to separate images for the left and right eye, and then match them with Cinema 3D glasses which were specially designed to receive each image. The intended result is a smooth 3D picture without the viewer experiencing eye fatigue or dizziness.

In other 3D-related activity, earlier this month, LG announced plans to unveil its glasses-free 3D smartphone, the LG Optimus 3D, at this year’s Mobile World Congress, according to a Mashable report.

While rumors have been flying for some time surrounding the launch of this new device, and images have been available, it is just now that LG has gone on record with some of the phone’s specifications.

Positioned as LG’s most advanced smartphone, the LG Optimus 3D will offer a glasses-free LCD panel, and a dual-lens camera for 3D recording, as well as HDMI and DLNA on the connectivity front.

As reported previously by TechZone360.com, LG has been struggling in the market as of late, posting its first quarterly loss in nearly two years, attributed to falling prices for flat screen televisions and stiff mobile phone competition from devices like the iPhone.

The company lost $229.4 million in the three months ending Dec. 31. LG reported more than $320 million in net profit just one year earlier.

LG announced last month the availability of the LG Optimus 7, a phone with features like GPRS, URL, Bluetooth and more. The phone was announced to coincide with the official unveiling of Windows Phone.
