"Two Samsung Galaxy Tab prototypes were on display in Japan this week, a 7-inch and 10.1-inch model with AMOLED displays.The 10.1-inch LCD measures a mere 1.8mm thick, thanks to a new manufacturing process using a resin substrate.
The display runs at 1024 x 600 – the same as the current Galaxy Tab and the new 7-inch Super AMOLED – with a 1,000:1 contrast ratio and 250cd/m2 brightness. Its the measurements which are vital, however: just 0.44mm thick and 28g when you discount the backlighting unit, whereas a regular Samsung LCD (with a glass substrate) would be 1.26mm thick and weigh 130g."
Looks like you might need to wait for a few years though.
Photos look good
