The LG Optimus 3D was the world's first phone to ship with two rear cameras, both of which were five-megapixel sensord. It was also known as the LG Thrill 4G when sold via AT&T in the US market.
The device offered glasses-free 3D viewing on its WVGA display with the 3D effect being generated by a parallax barrier screen. Users were able to watch 3D video content captured using the dual-lens camera. They could also access 3D content available on YouTube and play 3D-enabled games which were pre-installed on the phone.
The Optimus 3D reflected a trend towards offering 3D-enabled smartphones being announced shortly before
HTC’s Evo 3D.
The introduction of the 3D capability was used as an effort to different LG’s smartphone from rival high-tier products at the time. It was also complementary to LG’s growing range of 3D TVs. Optimus 3D owners could sharing and view 3D videos stored or captured on the smartphone with a 3D TV using an HDMI cable.
Despite LG following the Optimus 3D with the Optimus 3D Max, the technology did not prove popular with consumers, with many owners complaining that prolonged viewing of the glasses-free 3D display caused headaches.
