Today I got to see the LG Optimus 3D here at Mobile World Congress in Barcelona. I was impressed. Of course I cannot really capture it in a pic; but here it is anyway.

It really is 3D, which is amazing after a lifetime of 2D screens, and with no spectacles required.

The trick is that there are two screen images. When you look at the screen, your right eye gets a slightly different angle on the screen than your left eye. The technology uses that different angle to deliver a different image to each eye. At least, this is how it was explained to me.

There is also a dual-lens camera so you can take your own 3D pics and videos. The Optimus 3D has a 1GHz OMAP4 dual-core processor, and HDMI output for connection to high resolution external displays.

3D is cool and makes for some immersive games. But how much extra will customers be willing to pay for 3D on a Smartphone? Interesting question.
