The Wing's second screen can either act independently of the larger screen while it is displaying a film, for example, or can complement it as a controller for gaming and media.

However, some of this functionality relies on using pre-installed browsers.

One expert said it was one of the "more radical designs" he had seen.

LG showed off a set that can be fitted almost flat against a wall while Samsung teased a new kind of TV - designed to look like a painting - that displays art when not in use.

Samsung also unveiled a flagship set boasting greater brightness levels than before.

Others, including Sony, also revealed new models.

Samsung's flagship 75in (190cm) QLED 4K TV features the latest version of its quantum dot technology - tiny particles that emit different colours of light. These now feature a metal material that the firm says allows for better colour reproduction.

Reports suggest that the Android handset is upping its camera game with the inclusion of a Sony-made 20-megapixel sensor on the rear.

It also promises to be a powerful beast, with a Snapdragon 820 processor running the show, according to Mihai Matei of G for Games.

File this one under rumour for now, but Matei's sources have proven accurate in the past, bringing us solid information about Apple's hardware plans.

Previous reports suggest that the LG G5 will embrace recent developments in biometric security with the inclusion of iris-scanning technology.

That all seems to be changing now, as the company just recently announced a newer, larger addition to its G Pad line. Could this new device be a viable option for those looking for a high-end Android tablet, or will it fall short against other big devices from the competition? To help answer those questions, we go hands-on with the newly-announced LG G Pad 2 10.1.
