LG will showcase a 4.3-inch, glasses-free 3D display for mobile devices at the 2011 Consumer Electronics Show (CES) in Las Vegas, which opens later today.

The WVGA touchscreen display boasts a resolution of 480 x 800 pixels, and according to LG, enables users to watch videos or play games in 3D, with no need for glasses, and without straining their eyes.

The display uses applied parallax barrier technology, which delivers a series of light-blocking slits attached to the front of the LCD panel. The slits, or barriers, ensure that the left and right eyes see different images, creating an illusion of depth and a 3D effect. LG says it has also drastically reduced crosstalk, leading to means smoother, brighter, images, and a wider viewing angle than on previous parallax displays.

“LG sees tremendous growth potential in the 3D mobile display market,” says LG Mobile president and CEO, Dr. Jong-seok Park. “With our key understanding of displays, entertainment and mobile technology, LG is looking forward to debuting this exciting new way to watch 3D movies or play games on your mobile phone.”

Also at the show, LG will stage the first ever mobile demonstration of Wi-Fi Direct on an LG Optimus Black handset. Wi-Fi Direct offers hotspot-free wi-fi connectivity, enabling peer-to-peer connections between Wi-Fi Direct-capable devices for easy sharing of apps, videos and other content between the devices. It can be used, for example, to transfer photos from a phone to a printer, or to sync data between a phone and a PC.
