However, the no-glasses 3D concept is being demonstrated in a larger screen TV screen form factor as Toshiba, Sony, and LG all showed prototype glasses-free 56-inch 3D TVs at the 2011 Consumer Electronics Show.
What makes these TVs groundbreaking is that they sport 4K resolution (four times more than 1080p) for 2D images, and full 1080p for each eye in 3D mode. However, the viewing angle is limited for 3D viewing (about 15 degrees on either side of the center of the screen), which makes them currently impractical for general consumer availability, but the race is on.
With Toshiba, LG, and Sony all onboard with this developing technology, it will be interesting to see which one makes it to store shelves first. In talking to Toshiba reps at CES 2011, they seemed confident that Toshiba will be ready by 2012. However, before no-glasses 3D is viable, it must allow for wider viewing angle and must also be affordable. However, it is no longer a matter of if no-glasses 3D TV is possible, but when it can be made available to consumers.
In another encouraging note, "AutoStereoscopic Displays" (the technical name for no-glasses 3D TVs) being developed for the consumer market, are designed to work with all current 2D and 3D systems now in use (although LG's prototype is currently only capable of displaying 3D). In other words, you will be able to watch TV in either 2D or 3D, and if you own a 3D Blu-ray Disc player, 3D Blu-ray Discs, or 3D compatible home theater receiver, they will be compatible with all no-glasses 3D TVs when such sets are available. This is an absolute requirement if no-glasses 3D TVs are to be acceptable to consumers.
