NEC really caught our attention last month when we learned of the company’s N-05D Android, which measures-in at an astonishingly thin 6.7 millimeters. That’s not the only new model the manufacturer has been working on, and it recently showed-off a few of these handsets from its MEDIAS line in advance of the Mobile World Congress.

The hardware on the N-05D looks a little different here compared to the last time we saw it, with a front-facing camera now visible where none was earlier. We just hope that, whatever hardware changes NEC needed to make, it manages to keep the phone’s thickness down to the same impressive figure.

The next model NEC featured is a larger-screened handset, though we don’t yet have any precise measurement. From the looks of things, though, we’re in 4.7-inch territory here, if not larger. NEC talks about the phone’s “ultra-narrow edge”, but largely due to translation issues, it’s not clear if it’s discussing phone thickness or the width of the handset’s bezel surrounding the screen.

Easily the most eye-catching of the three, the last NEC Android here sports an uncommon dual-screen design, causing us to think back to the experiment that was the Kyocera Echo. If anything, this model most closely resembles Sony’s Tablet P, with a similar hinge-in-the-middle clamshell design. Here, though, it looks like the phone might be able to fold-through a full 360 degrees, giving you extra options on how you might use it.

All three of these NEC Androids are already outfitted with Ice Cream Sandwich and are LTE-enabled. We’ll try to get a closer look at the group as the MWC gets started.
