LG said Wednesday that its new Optimus 3D smartphone was launched by the AT&T in the United States this week. The new LG Thrill 4G smartphone sports a 4.3-inch display that allows users to record 3-D videos, take 3-D still images and look at 3-D images without special glasses, LG said.

The LG Thrill 4G introduces a number of technologies, including a dual-core (1GHz Cortex A9 ), dual-channel and dual-memory architecture.

The Android-powered mobile phone will have to compete against HTC's EVO 3D.

The Thrill 4G is available at US$99.99 with a two-year contract with AT&T Inc.
