CES: LG shows glasses-free 3D screens

Screens will bring 3D to smartphones

LG Electronics showed it's serious about 3D in mobile devices, introducing a new 4.3in glasses-free 3D screen for mobile devices and a similar prototype 7in 3D screen on a mobile TV.

The 4.3in 3D display boasts a WVGA touchscreen with a resolution of 480x800 pixels and is aimed at smartphones meant for movie viewing and gaming, the company said.

The company used an applied parallax barrier technology to create the glasses-free 3D effect. 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 company believes the technology reduces any doubling of the image, called crosstalk, and makes for much better glasses-free 3D viewing from wider angles than before.

LG also showed off a larger glasses-free 3D screen, a prototype mobile digital TV with a 7in screen. The larger screen size is big enough for a tablet device.

The company worked with LG Display to build the screens.

A number of companies, including Asus, have expressed interest in developing mobile devices with 3D capabilities but have said they would only move forward on such gadgets if high-quality glasses-free screens became widely available.

LG also introduced new lines of other 3D products, but these still require specialised 3D glasses for viewing.

The company introduced the new LG Cinema 3D TV, the LW6500, that has 3D technology similar to that in movie theaters, according to LG. It said the new 3D glasses with the LW6500 are more comfortable and more affordable than before.

LG also has 3D Blu-ray Disc players, 3D monitors, 3D laptops and 3D projectors on show at CES.
