Since bending the display is difficult, crafting a device that uses one effectively is even more difficult. In order to create a flexible product, manufacturers need to know how to make each component flexible. Batteries are particularly difficult to bend because the current technology requires batteries to keep their shape. After being bent, batteries are short-circuited and, if shorted too far in the housing, can explode.
Both LG and Samsung have been working on a flexible battery for many years, but the technology is still not available. So far, the only way to use a curved display is to make a device that bends on the hinge. This concept works with the Lenovo Yoga Book, which is equipped with a touchscreen and a touchpad that doubles as a drawing tablet. With the hinge, device manufacturers can potentially use fixed batteries and silicon, but add a fold to them.
We are still waiting for the first device to hit the market, but when it arrives, we can expect durability and endless possibilities in design and innovation. Over the last few years, the patterns of phones and tablets have been outdated, and flexible displays can make them exciting again.
