I thought active-shutter glasses for 3D were the best, but then I find this cnet article today that talked about passive coming back as an alternative at CES?
So why the switch? The big guys, Sony and Panasonic, aren't changing their pitch--they're sticking it out with active. However, LG, which still offers active-shutter 3D TVs, is a large producer of display panels for many in the TV manufacturing industry and has recently been able to produce a passive display at a more reasonable cost, noted David Wertheimer, CEO and executive director of the Entertainment Technology Center at USC. The film applied to create passive displays had previously been more cost-intensive to produce, which is one of the reasons many of the first 3D models used active-shutter technology.
