Lenovo presented a prototype of a notebook Thinkpad that had a very particular technological feature: the substantially increasing width of the screen.
The laptop in question appears to be a regular ThinkPad with a standard 4:3 screen, but when a small switch is activated on the right side of the chassis, mechanical motors extend the display, effectively "unrolling" it from underneath the keyboard vertically. With an odd 8:9 aspect ratio, the laptop in question displays a normal ThinkPad with a 12.7-inch screen.
LG has previously demonstrated a TV that can extend in a similar manner, but in this case everything is integrated inside a regular laptop, with the screen being "additional" that is housed inside the chassis without taking up much space.
The standard version displays a resolution of 20241604, while the extended version displays a resolution of 20242368.

Sharp uses Lenovo's own technology to produce the 8:9 aspect ratio: it's akin to doubling 16:9, as if you had two such screens stacking on top of each other.
Such a device is suitable for those who desire more screen space without having to give up an extremely portable device, as well as those who desire to make more use of the vertical layout, such as programmers or even those who use spreadsheets or simply text files.
Lenovo claims that the mechanism will last 20,000 or 30,000 years, but the issue hasn't yet been thoroughly tested, just as the battery will be tested in the future.
