LG Electronics has a mobile digital TV (MDTV) that displays 3D images and delivers social networking services like Twitter, all on a device that fits in the palm of your hand, the company said Monday.

The company said its prototype 7-inch receiver will be demoed this week at the 2011 National Association of Broadcasters Show in Las Vegas. The device will be the first MDTV that displays 3D images broadcast via the ATSC Mobile DTV Standard, according to LG Electronics.

And there’s no need for special glasses to view 3D images on the device—the prototype’s auto-stereoscopic capability means users can see 3D TV images with the naked eye, the company said.

“The ATSC Mobile DTV standard offers broadcasters remarkable flexibility to address the changing demands of consumers and advertisers,” said Skott Ahn, LG Electronics president and chief technology officer, in a statement.

The prototype also features a new application developed with Roundbox that LG is calling “Tweet-TV.” The MDTV app displays viewer tweets interactively on the prototype MDTV receiver while a program is airing. An MDTV transmitter from Harris delivers tweets received as data files, displaying them on a transparent panel that covers part of the LG device’s MDTV screen.

The prototype also delivers electronic couponing and video-on-demand, according to LG.

At the NAB Show, LG Electronics will also show a prototype of its first Android-enabled smartphone prototype with MMDTV reception. The 3.2-inch smartphone runs Google’s Android 2.2 Froyo operating system and is powered by LG’s second-generation MDTV chip, the company said Monday. It has a 3-megapixel camera, GPS, Wi-Fi, accelerometer and digital compass.
