LG Electronics on Monday unveiled the Optimus G Pro smartphone whose full high-definition screen offers images twice as bright and clear as previous models. It will go on sale through three major mobile providers on Wednesday.

This is the second full high-definition smartphone in the domestic market since Pantech's Vega No. 6 early this month.

Korea's major handset makers are all launching models in the first quarter. Samsung Electronics is next up with a new HD model in the popular Galaxy series next month.

The Optimus G Pro has a 5.5-inch LCD screen, a 13 million pixel built-in camera in the back of the body and a 2.1 million pixel camera in the front -- the best specs in the country. The apps processor is more than 20 percent stronger than in the previous model, the Optimus G, the company claimed.

It also features enhanced camera functions including taking pictures of moving objects, and also allows users to open two windows on the same screen.

The device runs on Google's Android 4.1 Jelly Bean operating system. It is 9.4 mm thick and weighs 172 g and costs W968,000.
