3D can be simple and inexpensive - - no shutter glasses.

I just came across a Laptop by Asus, the AS5738DG-6165 What's so great about it? Well, it has a nice 15.6" 1366 by 768 LDC panel (16:9) with LED backlighting and it does 3D using "Tridef" 3D technology by DDD for not much more money than a regular laptop.

As far as I can determine, "Tridef" displays 3D by circularly polarizing the light from each pixel individually so that 50% of the pixels can be dedicated to the right eye and 50% to the left eye when viewed through passive glasses similar to the ones for Avatar in 3D theatres. For 2D work without glasses, both eyes see all pixels.

Obviously, there is a 50% loss of horizontal resolution to each eye for 3D displays, but the human brain makes that loss virtually undetectable while you enjoy a very impressive 3D picture.

You can buy shutter glasses and fast switching displays if you want, but my bet is on this simple and inexpensive polarized display with passive glasses that gets you the complete 3D experience for a lot less complexity and money. I think this is the way it will be done in time - -
