Remember that stretch of a few weeks in 2011 when everyone was thrilled about lenticular 3D displays? LG does, and would like you to think that it's still every bit as exciting. That's the inescapable conclusion behind the LG CX2, AKA the Optimus 3D 2, newly leaked by ETnews. The phone is likely strutting its three-dimensional stuff prior to an official debut at Mobile World Congress. According to the leak, the new screen greatly improves both the 3D effect and legibility, thanks to an IPS-based screen.
