Every wanted a the big screen of a top smartphone, but didn't want the inconvenient bulk of a phablet? Then the answer could well be in having a roll-up screen - that  contracts to fit your pocket - and then expands to meet your need for a bigger viewing area. It sounds like something straight out of Alice in Wonderland, but such magical screens have been the biggest talking point of the first two days of CES 2021.

The giant tech show is a virtual event this year - so we haven't had the chance to get our hands on these futuristic-sounding products. However, we have seen the videos of how these would work in real life, and you can't help but want one!
