LG can also do glasses-free 3D.
LG unveiled the DX2000 Cinema 3D monitor. It will start shipping in South Korea within the next two weeks. The LG DX2000 3D Display uses eye tracking to enhance the 3D viewing experience. Toshiba uses similar technology on the new 3D Qosmio F750 laptop.

The DX2000 monitor has a webcam on top that tracks the users eyes. This gives users of the DX2000 the freedom to move their head around and still maintain a good 3D display. Glasses-Free displays without eye tracking require you to stay in the sweet spot to see the optimal 3D effect. As far as I understand the Korean press-release the DX2000 has a 2D to 3D converter function.
The 20-inch DX2000 Glasses-free 3D monitor sells for 1.29m Won (~$1,200). This glasses-free 3D monitor will be marketed as LG D2000 outside of Korea later this year.
