Tablets are really useful devices, but their big screens always make them 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 1 into the hand?

Now something like a tablet-shaped but fold-able phone is about to become 2. In February, South Korean electronics company Samsung and China’s Huawei both unveiled fold-able phones Galaxy Fold and Huawei Mate X 3. Mobile phone use has entered the “fold-able future”, The Verge noted.

The technology could change our lives in significant ways. These devices, due to their 4 screens, give us the larger screens we want. Meanwhile, they still fit easily into the pocket. As USA Today noted, they’re “the 5 of a small tablets and smart-phone, all in a single device”.

The technology could 6 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 7 available space.

In a keynote address, Samsung’s senior vice president of mobile product marketing, Justin Denison, called the fold-able screen “the 8 for the smart-phone of tomorrow.” “It’s a balank canvas for us to do something beautiful together,” he said.

So is there nothing to stand in the way of the fold-able future?

According to tech news website Android authority, the necessary displays were difficult to produce. In 2012, nine out of every to OLED screens produced were 9. Today, that 10 percent rate has been improved to between 50 and 90 percent. However, at present these fold-able devices are expensive. For example, the price of Huawei Mate X is 17,500 RMB. That’s a price that may 10 the majority of people.

But if the fold-able device isn’t going to change the world overnight, there is no doubt that it is coming.

Patrick Moor-head, an industry analyst told The Verge, “Few are debating if fold-able or roll-able mobile displays are the future of smart-phones; the only question is when and by whom.”
