Samsung, fresh from showing off a Super-AMOLED version of its Galaxy Tab over at the FPD International Expo in Tokyo, has now unleashed a 10.1-inch LCD prototype device.

Back in September, at IFA, Pocket-lint was on hand to hear DJ Lee, head of global sales and marketing at Samsung Mobile HQ say: "Based on our market research, people have different desires, so we are definitely going to have different sizes of tablets. And there will be tablets at different price points too".

This was backed up by his boss JK Shin who said: "Next year, you will see a variety of different tablets from our company. There will be an entire tablet device portfolio".

And chances are a 10.1-inch version could be the next size option to come to market, following the prototype demo.

The model being paraded has a 1.8-mm thick LCD display with a 1024 x 600 resolution, 250nits brightness, and covers 50 per cent of the NTSC colour gamut.

The prototype model is actually being described as an "electronic book reader", but I think we all know where this 10.1-inch LCD is going to turn up first.

The Samsung Galaxy Tab is seen by some as the best pound-for-pound tablet device in the world, but until we see and actual 10-inch model, it is still difficult to properly compare it to the iPad.

If and when it does arrive, it will be a real heavyweight title fight.
