This is a concept phone, but does seems to offer an alternative to the folding phones in the future
Chinese electronics company OPPO has revealed a concept smartphone, called the X 2021, which expands by rolling out its screen on a miniature conveyor belt.
Companies from Samsung to Motorola, Microsoft and Huawei have tried to achieve a similar size-changing effect through the much-hyped novelty of folding screens.
But the OLED screen in the X 2021 simply unfurls like a scroll, growing from 17 centimetres to 18.7 centimetres at the slide of a button.
This is possible through a trio of technological innovations, centred around the roll-out mechanism.
The flexible OLED screen is laminated onto a steel “warp track”, which resembles a conveyor belt or the tracks of a tank, allowing it to be rolled out when needed while strengthening it and maintaining its shape.
A “two-in-one plate” makes up the body of the phone, which essentially consists of comb-like units that are interlaced to form a single surface behind the screen.
When moving into tablet mode, these are cleaved apart to accommodate the display’s expansion, while always leaving a certain number of “teeth” supporting the centre of the display to prevent it from collapsing inward.

Just be careful if you put this expandable phone in your trouser pocket
