Ceatec, Japan's largest electronics show, is over for another year. We spent a week rushing around Makuhari Messe near Tokyo checking out some of the coolest, most futuristic gadgets and developments that Japan's electronics industry has to offer.

Here's some of the best of what we found:

Toshiba's no-glasses 3D TV

The big star of Ceatec 2010 was a new 3D television from Toshiba. It attracted hordes of people and sometimes a queue that was three hours long.

What's the big deal? The TV doesn't require glasses to see the illusion of depth. It's the first of its kind from a major consumer electronics manufacturer, although smaller companies have shown similar technology.

In a review we found it gave a good-looking high-definition 3D picture, but like systems that require glasses, the technology is far from perfect.

Pioneer heads-up display

Pioneer provided a glimpse into the future of driving: a heads-up display for drivers that hooks up to a mobile phone.

The prototype uses a laser to display images on a screen that would be mounted between the driver and the windscreen. The images are generated from a smartphone, which also provides up-to-date traffic information. Pioneer hopes to begin selling it in 2012 as an after-market add-on and is also talking to car manufacturers.

Fujitsu dual-screen mobile phone

Looking ahead to future LTE mobile service, Fujitsu was showing off a prototype mobile phone with two screens.

LTE will boast data speeds several times faster than current 3G so is expected to spur services that store data online. The handset uses the two screens to help clarify when the user is working locally and when they are working with online-based information. The addition of a second screen means there's no keypad.

No-wires charging

If you're constantly frustrated by the need to run a cable to charge a portable gadget then this will be of interest. NTT DoCoMo was showing some prototype mobile phones and batteries based on a new wireless charging standard called Qi (it's pronounced "chi").

The system replaces power bricks and cables and just requires a user place their mobile phone on a charging pad. (Here is a video demonstration.)

TDK's flexible OLED screens

TDK attracted a constant crowd at Ceatec for its flexible OLED screens. The screens are just 0.3mm thick and so can gently bend while still displaying images or information.

They'll bring benefits even when a bend isn't required: because they are made on plastic, they're much more durable than today's glass-based screens and much more difficult to break. (See them on show in this video.)
