    Tablets are really useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn’t it be great if there were a phone with the powers of a tablet that could be folded up and fit neatly into the hand?

Now something like a tablet-shaped but foldable phone is about to become available. In February, South Korean electronics company Samsung and China’s Huawei both launched foldable phones, the Galaxy Fold and Huawei Mate X respectively. Mobile phone use has entered the “foldable future”, The Verge noted.

The technology could change our lives in significant ways. These devices, due to their bendable screens, give us the larger screens we want. Meanwhile, they still fit easily into the pocket. As USA Today noted, they’re “the combination of a small tablet and smartphone, all in a single device”.

The technology could change other devices, too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers. In crowded modem cities, they will help us to maximize available space.

In a keynote address, Samsung’s senior vice president of mobile product marketing, Justin Denison, called the foldable screen “the foundation for the smartphone of tomorrow”. “It’s a blank canvas (画布) for us to do something beautiful together.” he said.

So is there nothing to stand in the way of the foldable future? According to tech news website Android Authority, the necessary displays were difficult to produce. In 2012, nine out of every 10 OLED (二极管) screens produced were imperfect. Today, that 10 percent rate has been improved to between 50 and 90 percent. However, at present these foldable devices are expensive. For example, the price of Huawei Mate X is 17,500 RMB. That’s a price that few people will be able to afford.

But if the foldable device isn’t going to change the world overnight, there is no doubt that it is coming. Patrick Moorhead, an industry analyst told The Verge, “Few are debating if foldable or rollable mobile displays are the future of smartphones; the only question is when and by whom.”
