Eizo is showcasing a glasses-free 23 inch HD 3D LCD screen called the Nanao at the Fukuoka December 1st to the 3rd. The 1080p panel uses a proprietary system with a directional backlight that causes a disparity in the time the stereoscopic image reaches your eyes creating the 3D effect. Aberrations such as Moire are not present since no lens or barrier is used.
The 3D effect is at its best at a viewing angle of about 1 meter, but the the horizontal stereo tolerance is about 65mm so you need to pretty much be looking at it straight on.
Its a heavyweight for a 23 inch panel coming in at 35lbs and, as you can see from the image above, quite bulky. In a world of sub-1 inch bezels, the Nanao looks a little awkward. Suffice it to say, I don't see it doing too well in the consumer.

I could be interesting to use this in retail digital signage although its size would limit it to a small aisle end cap.
Its unclear what the MSRP will be but it will likely be pricey.
