A few years ago, many were dreaming of having a smartphone with curved display. Today, there are many smartphones with curved display and now people can't wait to see first bendable-screen smartphones, which according to Samsung isn't that far away.

There were already some prototypes, but we have yet to see first commercial smartphone with flexible screen. Talking about the company's flexible-phone future, the president and CEO of Samsung Electronics North America Gregory Lee has said that it has taken a long time to figure out how to make them at a reasonable price, and added that such handsets are "relatively right around the corner."
