LG Rolly Keyboard is a folding keyboard for your tablet or smartphone

However much on-screen keyboards improve, they're no replacement for a good, old-fashioned keyboard. Traveling with a tablet, it might not be convenient to lug about a full-sized wireless keyboard but LG thinks its Rolly Keyboard could be the answer.

As the name suggests, this is a portable keyboard that 'rolls' up for easier transportation -- well, it rolls up into a square stick rather than a round roll, but you get the idea. Also known as the KBB-700, the Rolly Keyboard features almost full-sized keys, and can be paired with two devices via Bluetooth.

The keyboard is due to hit the US in September -- although LG hasn’t shared pricing details or an exact launch date yet -- and will roll out to Europe, Latin America and Asia later in Q4. The company says the 17mm key pitch is "nearly as generous" as desktop keyboards, and to make it easier to use in conjunction with your smartphone or tablet, two fold out support arms are on hand to cradle your device.

While price is yet to be revealed, Seo Young-jae, VP of Innovative Personal Devices at LG, describes it as a "premium input device", so it's possible a premium price tag will be attached. LG will give more details at IFA 2015 in Berlin at the beginning of next month, but for now you can check out the video below to see the keyboard in action:
